INTRODUCTION

It is a generation since a dictionary of explosives has been published, and, in the meantime, many new explosives have been introduced. It is hoped, therefore, that this small volume, giving concise information about these special materials, may prove useful to those who have to deal with them. In Cundill and Thomson’s “Dictionary of Explosives,” issued in 1895, there are many entries of the names of inventors and of mixtures which had been proposed but have never been used commercially, nor are likely to be. As modern explosives were then in their infancy, it was no doubt wise to insert all the available information whether it appeared to be important or not; but now it seems to me better to restrict the scope of the dictionary so as to keep its size within moderate limits. Practically only explosives with special or proprietary names are therefore dealt with here. For information concerning chemical substances, such as the nitro-toluenes and other nitro-compounds, reference should be made to the textbooks on explosives and chemistry.

A few words may, however, be said here about the nitrocelluloses. These are made by treating cellulose with a mixture of nitric and sulphuric acids, and then purifying the product by washing it thoroughly with hot water. The variety of cellulose most used for this purpose is cotton, and the product obtained from it is frequently called nitrocotton, three special varieties of which are collodion cotton, pyrocollodion and guncotton (q. v.). The only other form of cellulose which is nitrated on a commercial scale is “chemical cellulose” obtained by the treatment of wood or straw. Nitrated wood cellulose has long been used for the manufacture of smokeless powders for shot-guns, and during the War the Germans made powders for rifled fire-arms from it.

No trouble has been spared to make the dictionary complete and accurate, but there must inevitably be omissions and errors in it, especially as regards the explosives of foreign countries. The author will be grateful for any additional information that may be sent him.

Explosives may be classified in various ways, according to the purpose of the classification, but the great majority of them fall naturally into two main divisions: propellants and high explosives. Propellants explode comparatively slowly, and are used to propel projectiles from fire-arms. High explosives are much more rapid in their action, and are used for bursting and shattering. Propellants are of two sorts, according as they are intended for use in shot-guns or rifled fire-arms. Those for shot-guns burn more rapidly than those for the latter, but both practically always contain a considerable proportion of nitrocellulose, gelatinised by means of such solvents as acetone or ether-alcohol, according as it is of high or low nitration. Some contain also nitroglycerine, and are then called nitroglycerine powders, whereas those that do not contain this substance are termed nitrocellulose powders. Many powders also contain other ingredients, as may be seen from the compositions given in this dictionary.

Of high explosives an important class is used for charging shells and bombs. As a rule, but not necessarily, these are not the same as the explosives used for mining operations and other general blasting purposes. Another important class is that of the coal-mine explosives, which are designed to give only a short and comparatively cool flame so as to diminish the danger of igniting fire-damp and coal-dust. Nearly half the explosives in this dictionary are coal-mine explosives. The reason for this large number is that no finality has yet been reached as to the best and safest explosives to use in coal mines. When more experience has been gained it is probable that the number of these explosives on the market will be reduced. In England the Permitted List has recently been cut down considerably.

In Great Britain these coal-mine explosives have to be submitted to the Inspectors of Explosives, and are subjected to tests for safety and strength. If they pass they are placed on the list of “Permitted Explosives,” and the compositions are published in the Explosives in Coal Mines Orders. In these Orders the upper and lower limits of the percentage of each constituent are given, but in this dictionary intermediate percentages are given so that the sum for any explosive amounts to 100. In the Explosives in Coal Mines Orders the percentage of such a substance as wood, meal or starch, is given in the dried condition, but here it is given in the air-dry state on the assumption that it then contains about 10 per cent. of moisture.

In France and Belgium also the compositions of the coal-mine explosives are published, but in Germany, as a rule, only a list of the constituents is given, and sometimes an upper or lower limit for one or more of the principal constituents. Moreover, it is not stated explicitly whether the explosives are intended for use in coal mines or for general blasting purposes. In the United States of America, explosives intended for use in coal mines are examined by the Bureau of Mines, which, however, has no power to prevent the use of others because regulations on this matter are made by the individual states. If they pass they are placed on the list of “Permissible Explosives.” The compositions are not published, but the class of composition is stated.

Until the second half of the nineteenth century, gunpowder was practically the only explosive used on a considerable scale, and it was employed for all purposes. Consequently it does not fall into any of the classes mentioned, or rather it could be placed in several of them.

Another class of explosives that has not yet been mentioned is that of the primary igniters, of which fulminate of mercury may be taken as typical. The characteristic of these is that they can be exploded or ignited by a spark or moderate friction, and consequently they can be employed to fire other, less sensitive explosives. There are, however, practically no explosives of this class which possess special or proprietary names, and consequently they are not dealt with in this dictionary.

In 1914, 329,000 lbs. were used in coal mines, but the permit has now been repealed.

ALBIONITE.—A mixture of gelignite and ammonium oxalate. It was formerly on the Permitted List.

ALBIT.—A German chlorate explosive introduced in 1915 in consequence of the scarcity of nitrates due to the War. It is defined as consisting of not more than 80 per cent. sodium or potassium chlorate, not more than 4 per cent. nitroglycerine, and mono- or dinitro-hydrocarbons. It may also contain inorganic salts and carbon carriers such as vegetable meal, oils, soaps or carbohydrates. A variety made for use in coal mines is called Wetter-Albit or Kohlen-Albit.

ALDORFIT. See DORFIT.

ALKALSIT.—A German chlorate or perchlorate explosive made by the Dynamit A.-G. of Hamburg. It contains not more than 80 per cent. sodium or potassium chlorate, or not more than 80 per cent. sodium, potassium or ammonium perchlorate, and 19 per cent. of aromatic nitro-hydrocarbons and nitrocotton, also coal, hydrocarbons or carbohydrates, and nitrates. The chlorate mixtures must not contain ammonium salts. Alkalsit I contains not more than 27 per cent. of potassium perchlorate, ammonium nitrate, not more than 24 per cent. of sodium nitrate, not more than 8 per cent. of trinitro-toluene, also wood meal, flour and nitro-naphthalene. Alkalsit A contains not more than 55 per cent. of potassium perchlorate, ammonium nitrate, not more than 31 per cent. trinitro-toluene, and not more than 5 per cent. of a neutral liquid mixture of nitrated toluenes. Alkalsit B is similar except that it contains also ammonium nitrate.

It was made by the Société Anonyme de Vilvorde in Belgium, and was originally called Ugolite.

Rock Amasite and S.T. Amasite are non-permitted explosives of composition somewhat similar to the above.

AMATOL.—A mixture of ammonium nitrate and trinitro-toluene. The composition is shown by the figures placed after the name; thus Amatol 40/60 contains 40 per cent. ammonium nitrate and 60 per cent. trinitro-toluene, and Amatol 80/20 consists of 80 parts ammonium nitrate and 20 parts trinitro-toluene. These explosives are used very extensively for filling shell and other projectiles. The mixtures rich in trinitro-toluene can be cast after being heated to temperature above the melting-point of this constituent, but those rich in ammonium nitrate are stemmed into the projectile hot or pressed. Similar mixtures are used by the Germans and other powers under various names. In Germany it is called Füllpulver (q. v.).

AMATOXOL.—A mixture of ammonium nitrate and Toxol, which consists of trinitro-toluene and trinitro-xylene.

*AMBERITE.—A smokeless shot-gun powder made by Curtis’s and Harvey at Tonbridge. Amberite No. 1 contained nitroglycerine as well as nitrocotton and various other substances. According to “Arms and Explosives,” 1917, p. 78, a sample of Amberite No. 2 had the composition—

Insoluble nitrocotton

This is still on the market. It is a fibrous 42-grain bulk powder.

*AMIDE POWDER or Chilworth Special Powder was an early attempt at a smokeless powder. Under the name of Amidpulver it was used by the German artillery for some years in the ’eighties of the last century. Its composition was—

Ammonium nitrate

35-38

Potassium nitrate

40-46

Charcoal

14-22

See also Ammonpulver and Hebler Powder.

AMMONAL is a blasting explosive containing ammonium nitrate, aluminium powder, charcoal, and generally trinitro-toluene. It was patented in 1900 by G. Roth of Vienna, and the following are some of the compositions made by his firm at Felixdorf in Austria—

and modifications of this have been used largely in the British service. It is not suitable for use in underground workings as it forms on explosion the poisonous gas carbon monoxide, unless the proportion of ammonium nitrate be large. It has been used for charging grenades, and by the Austrians for trench howitzer bombs.

When the explosive is detonated, the aluminium is converted into the oxide, evolving no gas, but a considerable amount of heat, which increases the power of the explosive. The aluminium powder also renders the explosive easier to detonate.

Three explosives of this type passed the Woolwich Test, and were on the old Permitted List for coal mines, namely, Ammonal B, Ripping Ammonal and Saint Helen’s Powder (q. v.).

AMMONIAKKRUT was the first ammonium nitrate explosive. It was invented by J. Ohlsson and J. H. Norrbin, two Swedes, and was protected by English Patent 2766 of 1869. It consisted of ammonium nitrate together with 5 or 10 per cent. of charcoal, coal dust, etc., to which mixture was added 10 to 30 per cent. of nitroglycerine to make it less difficult to detonate.

AMMONITE is a coal-mine explosive of the Favier type, made by the Miners’ Safety Explosives Co. The original composition, which passed the Woolwich Test was—

Ammonium nitrate

*AMMONPULVER is a propellant which was used by the Austrians from 1890 to 1896 in guns of various calibres—

Ammonium nitrate

80-90

Charcoal

It was superseded by a powder of the ballistite type, but has been reintroduced recently by the Germans to replace a part of the charge of nitrocellulose powder in their field gun. The advantages claimed for it are small erosion of the gun, absence of muzzle flame, chemical stability, and cheapness. On the other hand, it gives high pressures, and if used by itself requires a gun with a specially large chamber; but the most serious objection to it is that on keeping, physical changes take place in the pellets, leading to the production of very high pressures. It is said that moisture promotes these changes. See also Amide Powder.

ASTRALIT.—An ammonium nitrate explosive containing a little blasting gelatine, made by the Dynamit A. G. Nobel of Hamburg. It has been used largely in Germany for a variety of purposes.

Astralit I and II are defined as consisting of ammonium nitrate, charcoal, vegetable meal, not more than 15 per cent. of aromatic nitro-bodies not more dangerous than trinitro-toluene, not more than 4 per cent. of blasting gelatine; also paraffin oil.

Astralit IV consists of ammonium nitrate, not more than 10 per cent. of aromatic nitro-bodies not more dangerous than dinitro-naphthalene, vegetable meal, and not more than 4 per cent. of blasting gelatine.

Astralit V, which has been introduced recently, contains up to 10 per cent. of potassium perchlorate in addition to ammonium nitrate, also vegetable meal, not more than 16 per cent. of aromatic nitro-compounds, and not more than 4 per cent. of nitroglycerine.

Gelatine-Astralit is a gelatinised or powdery mixture of the nitrates of ammonium and sodium (or potassium), not more than 50 per cent. of dinitro-chlorhydrin, not more than 5 per cent. of nitroglycerine, not more than 2 per cent. of collodion cotton, vegetable meal, aromatic nitro-bodies such as nitro-toluenes or nitro-naphthalenes, but not more than 4 per cent. of trinitro-toluene; also hydrocarbons.

Wetter-Astralit is a coal-mine explosive, and differs from Astralit in that part of the ammonium nitrate is replaced by sodium chloride.

Wetter-Gelatine-Astralit is also a coal-mine explosive, and differs from Gelatine-Astralit in that it contains also fatty oils and neutral salts, such as potassium chloride, sodium chloride or an oxalate.

*BALLISTITE.—One of the first military smokeless powders, invented by Nobel. It consisted of about equal parts of nitroglycerine and soluble nitrocotton incorporated together under water, then passed repeatedly through rolls and cut into flakes. It was adopted by a number of Continental powers, but in consequence of the severe erosion of the guns which it caused, it has been modified or abandoned. The percentage of nitroglycerine is reduced, and consequently it is necessary to use a solvent such as acetone. A little mineral jelly or other stabiliser is sometimes added.

As the sodium nitrate in the above is not equivalent to the ammonium perchlorate, part of the chlorine is given off in the form of the poisonous gas, hydrogen chloride (hydrochloric acid).

BLASTING GELATINE.—Nitroglycerine, stiffened by having collodion cotton dissolved in it. Discovered by Nobel in 1875. It contains about—

Nitroglycerine

93

Collodion cotton

and also often a fraction of a percentage of calcium or magnesium carbonate to increase its stability. This is the most powerful of all the explosives in common use.

BOBBINITE.—The only explosive of the gunpowder class the use of which is permitted in coal mines in England. In most foreign countries explosives of this class are not allowed to be used in them at all. The permission is only temporary, but has been extended to the end of 1920, and is restricted to mines that are not gassy or dangerous from coal dust.

BROWN POWDER. See COCOA POWDER.

BRUGÈRE’S POWDER consisted of—

Ammonium picrate

54

Potassium nitrate

46

It was stated to give good results in the Chassepôt rifle, but picrate mixtures are liable to detonate, and are therefore dangerous to use as propellants.

BULL DOG Gunpowder Pellets were used in coal mines. They contained the same constituents as Bobbinite, which superseded them, but in different proportions.

Explosifs  C  were mixtures of ammonium cresylate with ammonium or sodium nitrate. They were made in France at one time, but their manufacture was dropped, as they were more expensive to make than Grisounite, and no more powerful.

CAHUECIT.—This was invented in the ’seventies of the last century by R. Cahuc, and was manufactured at Dartford in Kent under the name of Safety Blasting Powder or Carboazotine. It is still made in Germany. The ingredients are—

to which are added a few per cent. of sulphate of iron. The incorporation is carried out with the assistance of a considerable quantity of water, which is afterwards evaporated off. The mixing is not very thorough. The explosive is a comparatively mild one, but is used sometimes for blasting basalt. In the German explosive the potassium nitrate may be replaced by the corresponding sodium salt.

AMMONCAHUECIT.—In this explosive the potassium nitrate is replaced mainly or wholly by ammonium nitrate, and it contains not more than 15 per cent. of trinitro-toluene or trinitro-naphthalene or other nitro-body.

The brand labelled “Fram” contains ammonium nitrate, not more than 25 per cent. of trinitro-toluene gelatinised with 4 per cent. collodion cotton, wood meal or other vegetable meal and neutral stable salts. The brand “Indra” is similar, except that it contains also not more than 10 per cent. potassium nitrate, and the percentage of trinitro-toluene may be raised to 20.

CAMBRITE is a coal-mine explosive of the Carbonite type made by Nobels at Ardeer. It consists practically of Nobel Carbonite, to which 8 per cent. of a cooling agent has been added. Unlike most of the explosives on the old Permitted List, it passed the Rotherham Test with practically no alteration—

CAMERON MINE POWDER.—There are a number of coal-mine explosives of this name on the American Permissible List. Nos. 1A, 2A and 2A LF are ammonium nitrate explosives, whereas Nos. 3A and 5A are nitroglycerine explosives.

*CANNONITE was a smokeless powder made by a firm called the War and Sporting Smokeless Powder Syndicate, Ltd. It consisted of about 86 per cent. of nitrocellulose mostly insoluble in ether-alcohol, and a few per cent. of barium nitrate, together with small quantities of some of the following: potassium nitrate, charcoal, lampblack, vaseline, rosin, stearine, dinitro-benzene, trinitro-toluene, potassium ferro-cyanide, graphite. For shot-guns the powder was of the forty-two grain type, dense and gelatinised. The rifle powder was colloidal. These powders were made in the ’nineties of the last century.

CARBITE D’ABLON is a sort of Carbonite made in France—

Nitroglycerine

CARBOAZOTINE. See CAHUECIT.

CARBO-DYNAMITE was an explosive patented by W. D. Borland. It differed from ordinary dynamite in that the nitroglycerine was absorbed in cork charcoal instead of kieselguhr. One part of the charcoal sufficed to absorb nine parts of nitroglycerine.

CARBONITE (or Karbonit) was one of the earliest and one of the most successful coal-mine explosives. It was first made by Bichel and Schmidt at Schlebusch in Germany in 1885, and after some modifications gave satisfactory results at the Neunkirchen testing station in 1887. It contains about 26 per cent. of nitroglycerine, 33 per cent. of a nitrate, and 40 per cent. of wood meal or starch flour, and small quantities of other substances. Nobel Carbonite passed the Woolwich Test and had the composition—

Nitroglycerine

26

Barium nitrate

4

Potassium nitrate

29

Wood meal

40·5

“Sulphuretted benzol”

0·25

Sodium and calcium carbonates

0·25

The Carbonite made at the works of the Carbonite Syndicate at Schlebusch, and imported into Great Britain, was practically the same as this, but they also made another explosive which passed the Woolwich Test, and contained 35 per cent. of nitroglycerine gelatinised with nitrocotton, and smaller proportions of nitrates and wood meal than are given above: this was called Extra-Carbonite. They have also made explosives to numerous modifications of this formula for use on the Continent. The essential feature of all of them is that they contain so much of the combustible constituents, such as wood meal, that most of the carbon appears in the products of explosion as carbon monoxide, and the temperature of the gases is consequently low.

Nobels at Ardeer also made a low freezing explosive in which part of the nitroglycerine was replaced by a nitro-compound. This was called Arctic Carbonite—

Nitroglycerine

Nitro-hydrocarbon

10·5

Potassium nitrate

Various manufacturers have made explosives of the type of Carbonite and placed them on the market under different names, such as Tutol, Kolax, Kohlen-Carbonite, Minite and Colinite. These, however, do not pass the Rotherham Test for Permitted Explosives, unless ammonium oxalate or other cooling agent be added, as in the case of Cambrite, Super-Kolax and Britonite No. 2.

On the Continent, explosives similar to Arctic Carbonite have been produced under the names Antigel de Sûreté and Ingélite.

There are several Carbonites on the American Permissible List. Of these Nos. 1 to 4 are in order of diminishing violence: Nos. 5 and 6 are low freezing varieties. There are also a number of other explosives of the Carbonite type on the List.

Ammonkarbonit is a German coal-mine explosive, containing about 80 per cent. of ammonium nitrate and 4 per cent. of blasting gelatine, together with 5 or 10 per cent. of potassium nitrate, and a combustible such as flour, starch or coal dust. Sodium or potassium chloride may be added as a cooling agent. It has been used for blasting clay.

Gelatine-Karbonit is a Carbonite containing ammonium nitrate, and a considerable proportion of nitroglycerine gelatinised with collodion cotton.

Halokarbonit is similar to Ammonkarbonit, except that a considerable proportion of the ammonium nitrate is replaced by other nitrates.

CARLSONITE was the first ammonium perchlorate explosive submitted to H.M. Inspectors of Explosives. It was proposed in 1898 by Carlson of Stockholm, and some of the mixtures were reported on favourably, but no licence was ever taken out in the United Kingdom for this explosive.

C.E. (Composition Exploding) is the same as Tetryl.

*CENTRALITE is not an explosive, but is a name given to a substance which has been used to modify the surface of smokeless powder, and make it burn progressively. The substance is dimethyl-diphenyl-urea. (See Brit. Pat. 29,882 of 1909.) It acts also as a stabiliser.

CHEDDITE is a chlorate explosive which has been rendered less sensitive by having the particles of chlorate coated with castor oil or paraffin wax. It is manufactured by the French Government at the Vonges Powder Works, and has also been made in other countries. The two types that have been most used in France are—

COLLODION COTTON is a variety of nitrocotton of low nitration, almost completely soluble in a mixture of ether and alcohol. It contains not more than 12·3 per cent. of nitrogen. It also dissolves in nitroglycerine and liquid nitro-compounds, rendering them gelatinous and so preventing their exudation.

*COOPPAL’S POWDER.—A Belgian smokeless shot-gun powder. Formerly it was much the same as Schultze Powder, consisting of nitrolignin carefully purified, and mixed with nitrates with or without the addition of starch. The following analyses were published in “Arms and Explosives” for July 1917—

CORDITE is the principal smokeless powder of the British Services. It was originally adopted in 1888, and is made by mixing nitroglycerine with guncotton and mineral jelly (a sort of crude vaseline), and incorporating them together with the aid of acetone, which gelatinises the guncotton. In consequence of the severe erosion of the guns experienced during the South African War the proportions were altered, some of the nitroglycerine being replaced by guncotton. The propellant thus “modified” is called Cordite M.D., whereas that of the original composition is Cordite Mk.I. Both are still in use, especially M.D.—

It is designed to give about the same ballistics as Cordite M.D. A further letter is sometimes added to show the form of the powder. Thus Cordite M.D.T. is M.D. pressed into tubes; S. stands for strip. The size is indicated by a numeral, which shows the diameter in hundredths of an inch of the die through which it has been pressed. In the case of tubular powder both the external and internal diameters are given approximately: e. g. Cordite M.D.T. 5-2.

CP_1 and CP_2 are varieties of nitrocotton (Coton Poudre) made in France, principally for the manufacture of Poudre B and other smokeless powders. CP_1 is a guncotton containing about 13 per cent. of nitrogen, and only about 10 per cent. of matter soluble in ether-alcohol. CP_2 is almost completely soluble in ether-alcohol, and contains about 12 per cent. of nitrogen.

CRÉSYLITE.—A French high explosive used for filling shell and other military purposes. Crésylite 60/40 consists of picric acid and nitrated cresol in about the proportions of 40 of the former to 60 of the latter. It melts below the temperature of boiling water. The nitrated cresol consists largely of trinitro-metacresol.

Crésylite No. 2 is simply crude trinitro-meta-cresol.

CRONITE is an American coal-mine explosive. There are two varieties on the Permissible List, Nos. 1 and 5, both of which are ammonium nitrate explosives.

DYNAMITE is a name that has been given to various nitroglycerine explosives. Dynamite No. 1 consists of—

Nitroglycerine

75

Kieselguhr

25

the explosive being held in the pores of the kieselguhr. In other dynamites the nitroglycerine is absorbed in a material like wood meal, and a nitrate is added to oxidise the latter on explosion.

In Gelatine Dynamite the nitroglycerine is gelatinised with collodion cotton. See under Gelatine.

American Dynamites are not generally gelatinised with collodion cotton. They are made in a number of grades, depending on the percentage of nitroglycerine.

For further details about various dynamites, see textbooks on explosives.

The Grisounites-couche are used in the coal seams as they have theoretical temperatures of explosion of 1500° or less, but N_1a has been replaced to a considerable extent by N_4, because the presence of a proportion of potassium nitrate is found to increase the safety; these are both coloured green. The Grisounites-roche have theoretical temperatures of explosion of 1900° or less, and are used in the rocks in coal mines. N_1b is dyed rose colour, and N_1c pale yellow.

Many explosives of this type are in use in different countries. On the old British Permitted List were Ammonite, Westfalite, Bellite and Roburite amongst others. Those now on the List contain ammonium or sodium chloride to enable them to pass the Rotherham Test, e.g. the later Ammonites, Bellite Nos. 2 and 4, Faversham Powder and Negro Powder.

GIANT COAL-MINE POWDERS are American coal-mine explosives on the Permissible List. No. 5 is an ammonium nitrate explosive, whereas Nos. 6, 7 and 8 are low-grade dynamites mixed with hydrated salts.

GIANT POWDER is a name given in America to dynamite. No. 1 is a kieselguhr dynamite containing about 75 per cent. of nitroglycerine. Many varieties, however, do not contain kieselguhr, but consist of nitroglycerine mixed with wood pulp, sodium or potassium nitrate, resin, sulphur or other combustible matter. The nitroglycerine is sometimes gelatinised with collodion cotton, or in the “Extra” varieties is partially replaced by ammonium nitrate.

GLONOINE was an early name for nitroglycerine.

GLUECKAUF.—A German explosive of the Grisounite type consisting of ammonium nitrate and vegetable meal, to which might be added any of the following: sugar, resin, fatty oil, potassium nitrate, sodium nitrate, dinitro-benzene, ammonium oxalate, copper oxalate, copper nitrate ammonia, or sodium chloride.

See Fuellpulver. Other substances used in German shell and bombs are trinitro-anisole, dinitro-benzene, hexanitro-diphenylamine and hexanitro-diphenyl sulphide, otherwise picryl sulphide.

GRISOUNITE.—A French coal-mine explosive. See FAVIER Explosives.

GRISOUTINE or GRISOU-DYNAMINE is the only explosive except Grisounite allowed in the more dangerous French coal mines. It consists of ammonium nitrate mixed with blasting gelatine. As the State monopoly does not extend to explosives containing nitroglycerine, it is made by private firms, but the compositions are regulated by the “Commission des Substances Explosives,” which in 1911 resolved that they should be uniformly as follows—

The calculated temperatures of explosion of the Grisoutines couches are below 1500°, and those of the Grisoutines roches below 1900°. The addition of 5 per cent. of potassium nitrate is found to increase the safety.

There are a number of explosives of this type made in other countries also, but they usually contain small proportions of combustible substances such as wood meal, and nitro-bodies such as trinitro-toluene. Of British explosives of this type, mention may be made of Monobel, Super-Excellite and Monarkite. German explosives of this sort include Salit, Tremonit, Donarit, Ammon-Karbonit and Astralit.

On the Belgian list of Explosifs S.G.P. is Grisoutine II., which is identical in composition with Dynamite anti-grisouteuse V.

*HALAKITE attracted public attention out of all proportion to its merits, of which it possessed none, in consequence of the extravagant claims made on its behalf by its “inventors” and their dupes. Early in 1917 the British Government caused an inquiry to be held, and the case for the explosive collapsed in a ludicrous manner. According to patent specification, No. 685 of 1915, the basis of the explosive was an admixture of lead nitrate with glycerine and other substances, and under the working conditions the glycerine was said to react with the nitrate to form a nitro-compound, which, of course, is not true. The substance actually submitted to the British and French authorities consisted of cordite mixed with lead nitrate, barium nitrate and lead chromate. This was stated by the promoters to be equally effective as a high explosive and a propellant! See “Interim and Final Reports of the Army Council (Halakite) Inquiry,” Cd. 8446.

HALALIT.—A German blasting explosive made by Nahnsen, containing not more than 65 per cent. of potassium perchlorate, ammonium nitrate, and not more than 32 per cent. of nitrated toluene, of which not more than 20 per cent. must be trinitro-toluene. It may also contain collodion cotton to gelatinise the liquid nitro-toluene, and sodium nitrate and wood meal or other vegetable meal.

Ammon-Halalit A, which has been introduced recently, is similar to Astralit V.

HALOKLASTIT. See PETROKLASTIT.

HAMMONIT.—A German blasting explosive containing not more than 40 per cent. of potassium or sodium perchlorate, not more than 4 per cent. of nitroglycerine, aromatic nitro-bodies, ammonium nitrate, sodium or potassium nitrate, neutral salts and vegetable meal or other combustible matter.

HASSIA-CHLORAT is an explosive that was introduced in Germany during the War. It consists of 65 per cent. potassium chlorate and 35 per cent. combustible, and it is claimed that the large proportion of the latter not only makes it a mild explosive, but also renders it comparatively insensitive. It is also called Spreng-chlorat.

HAYLITE.—A coal-mine explosive made by the National Explosives Co. There were three varieties on the Permitted List: No. 1 was also on the old Permitted List, but has now been repealed.

H.E. stands for High Explosive, used for charging shell or other military purpose.

*HEBLER POWDER was a so-called smokeless powder which was manufactured at one time in Switzerland. According to an analysis published by Cundill and Thomson, it was ordinary gunpowder in which about a fifth of the saltpetre had been replaced by ammonium nitrate. It did not appear to have a greater tendency to absorb moisture than ordinary powder. It was also called Wellite. See also Ammonpulver.

HECLA NO. 2 is an American coal-mine explosive on the Permissible List. It is an ammonium nitrate explosive made by the Du Pont Co.

HECLA POWDER is a brand of American dynamite.

HIMALAYITE.—A high explosive made from potassium chlorate, potato starch and a drying oil. The chlorate and starch are first heated together with water, and when dry the oil is mixed in. The explosive is said to have been adopted by the Portuguese for filling shell. It passed the chemical tests in England, but no licence was taken out for its manufacture.

HUDSON’S EXPLOSIVE.—A stiff blasting gelatine made by incorporating nitroglycerine and collodion cotton together with the aid of acetone. It was tried in America in 1889 for filling shell, but is not used now for this purpose.

HYGRADE COAL POWDER NO. 2 is an American coal-mine explosive on the Permissible List. It is a nitroglycerine explosive.

*IDEAL POWDER is a shot-gun powder made by Nobels.

IMPERIALITE is of no practical importance, but is interesting, as its history is that of the explosive one meets in the comic papers. The Marquis R. Imperiali had large private means and some knowledge of chemistry. He took out patents for a number of explosive mixtures and built a small factory in N. Italy, which started work in 1911. An explosion occurred the first day and killed five of the fifteen workers. Imperiali escaped and re-erected his factory. The day after it was restarted it blew up again and Imperiali was killed. The composition of the explosive that was being made is not known, but several of the mixtures for which Imperiali had taken out patents were decidedly dangerous.

*INDURITE was a smokeless powder patented by C. E. Munroe in 1893. It was made by incorporating guncotton with nitro-benzene to a hard mass. It was used for a time in the American Navy. Samples made in 1891 were still stable apparently in 1914, but some cases of instability occurred and it was given up.

INGÉLITE is the same in composition as ANTIGEL DE SÛRETÉ.

LIGNOSIT is a German blasting explosive containing a considerable percentage of ammonium nitrate. Lignosit I. contains also aromatic nitro-compounds, of which not more than 15 per cent. must be trinitro-compounds or wood meal, and not more than 6 per cent. of potassium nitrate, not more than I per cent. of collodion cotton and bauxite or salts, such as sodium chloride or carbonate.

Lignosit II. may contain up to 10 per cent. of collodion cotton, but no wood meal or nitro-compounds. It is somewhat sensitive.

Lignosit III. differs from I. in that it may contain up to 4 per cent. of blasting gelatine and contains no bauxite.

The object of adding the neutral salts is evidently to make the explosive safer in coal mines. When intended for this purpose it is called Wetter-Lignosit I. or III.

Lignosit IV. consists of ammonium nitrate, not more than 13 per cent. of trinitro-toluene, not more than 13 per cent. of aluminium powder, and wood meal.

METEOR AXXO is an American coal-mine explosive on the Permissible List. It is a low-grade dynamite containing a hydrated salt.

MIEDZIANKIT (also called Egelit or Kieselbacher Chloratsprengstoff) is a German chlorate explosive of the Sprengel class. It consists of porous potassium chlorate impregnated with not more than 10 per cent. of kerosene, having a flash point not below 30° C. It has met with some unfavourable reports, as it is found that results are not uniform unless the impregnation be carried out in special factories, the original idea having been that it was to be done shortly before use.

During the War a modification of the explosive was introduced for use in coal mines. This contains up to 30 per cent. of sodium chloride.

OXYLIQUIT is a blasting explosive consisting of liquid oxygen absorbed in some porous combustile material, such as absorbent cork, soot or kieselguhr mixed with petroleum. It was discovered in 1895 by Prof. F. C. Linde, and was tried on a large scale in 1899 in the construction of the Simplon tunnel. It is very cheap, and is safe in the case of a missfire, because in about half-an-hour the oxygen has all evaporated off and the charge becomes inexplosive. On the other hand, it is necessary to have the air liquefying plant near the scene of operations, and the charge must be fired soon after charging. These disadvantages prevented the adoption of the explosive, but during the War fresh trials were made in Germany in consequence of the scarcity of nitrates.

Liquid oxygen explosives are now used on a considerable scale by the Germans for military, as well as civil blasting operations. The name Oxyliquit, however, seems only to be applied to them when the explosive is made in the manner and with the plant of the Linde Company. See also Marsit.

PANCLASTITE.—A Sprengel explosive made by mixing liquid nitrogen peroxide with carbon bisulphide, nitro-benzene or nitro-toluene. It was proposed in 1881 by Turpin, and was tried by Germany for filling shell, the two constituents being contained in separate glass containers, which were broken by the shock of discharge. It was not adopted there on account of the inconvenience of dealing with a liquid which gives off poisonous fumes. It is a powerful and violent explosive, and is probably the same as the “Turpinite” about which sensational statements were made in the press early in the War.

RACK-A-ROCK is a Sprengel explosive which has been used extensively in America, and also in Siberia and China. It consists of cartridges of potassium chlorate mixed sometimes with oxide of iron, which are dipped shortly before use into a liquid. The latter is nitro-benzene or “dead oil,” a heavy hydrocarbon oil obtained from coal-tar, or a mixture of the two. The chlorate cartridges are enclosed in small cotton bags, and are placed in a wire basket suspended from a spring balance. They are dipped into a vessel containing the liquid until a quarter or a third of the weight of the chlorate has been taken up.

RASCHIT is a blasting explosive consisting entirely of salts readily soluble in water, invented by F. Raschig. The incorporation is carried out by dissolving the constituents in water, and evaporating the solution rapidly on a rotating steam-heated drum.

SAXONITE was the predecessor of Samsonite on the old Permitted List. It has practically the same composition, but wide limits are allowed. It also is used for general purposes. During the War potassium nitrate was replaced by sodium nitrate.

Ammon-SCHLESIT or Kohlen-SCHLESIT is a German coal-mine explosive containing ammonium nitrate and other nitrates, nitro-compounds, starch, neutral salts, not more than 4 per cent. of blasting gelatine, and not more than 2 per cent. of potassium perchlorate.

SCHNEIDERITE is a high explosive used by the French for filling shell. Its composition is the same as the Favier explosive N_1c.

*SCHULTZE POWDER was the first successful smokeless powder made. It was invented by Capt. E. Schultze of the Prussian Artillery, who appears at first simply to have impregnated little grains of wood with saltpetre (Eng. Pat. 900 of 1864). But later the wood cellulose was purified and nitrated, and then mixed with nitrates. The powder has remained the same as this until the present day, although the methods of manufacture have been developed and, indeed, revolutionised more than once. In “Arms and Explosives,” 1917, p. 75, the following analyses of different brands were given—

SEBOMITE is a French chlorate explosive resembling Cheddite, but containing tallow instead of castor oil.

SECURITE was one of the first coal-mine explosives. It contained ammonium nitrate and dinitro-benzene, and was therefore similar to Bellite and Roburite.

SECUROPHORE.—A Belgian coal-mine explosive containing nitroglycerine, nitrates, flour and other constituents.

SENGITE is a variety of Tonite introduced in South Africa as a substitute for Gelignite in consequence of the scarcity of glycerine due to the War. It contains guncotton and sodium nitrate, and sufficient moisture to render it safe to handle without diminishing its strength. The first four letters of its name stand for substitute explosive no glycerine. It requires a priming cartridge of gelignite or similar explosive. It is more expensive than gelignite, and consequently is not likely to be used when the scarcity of glycerine has been relieved.

SHELLITE.—A high explosive consisting of picric acid and dinitro-phenol, used for filling shells. The mixture possesses the advantage over straight picric acid that it melts at a lower temperature. It was for a time called Picrol.

SILESIA is a German blasting explosive consisting of potassium chlorate, the particles of which are coated with resin or oxidised resin. The latter is made by treating ground colophony, mixed with 10 per cent. of starch, with nitric acid. After washing and drying this is incorporated with the chlorate with the aid of alcohol, in which it is soluble. For use in coal mines sodium chloride is sometimes added. The following are examples—

SPRENGCHLORAT. See Hassia-Chlorat.

SPRENGEL EXPLOSIVES were patented in 1871 by Dr. Hermann Sprengel, F.R.S., the inventor of the mercury vacuum pump. They are made by mixing an oxidising substance with a combustible one, the essential features being that one or both of the substances must be liquid, and the mixing takes place shortly before the explosive is required. The mixture is exploded by means of a fulminate detonator. As oxidising agents, Sprengel mentioned amongst others nitric acid and potassium chlorate; nitrogen peroxide has also been used; as combustibles, a large number of substances including nitro-benzene, nitro-naphthalene, carbon bisulphide, petroleum and picric acid. For most purposes nitric acid is an inconvenient material to use. Porous cartridges of potassium chlorate constitute the oxidiser generally employed, the combustibles being hydrocarbon oils and nitro-benzene. This possesses considerable advantages, as there is no danger of a premature explosion until the constituents have been mixed. Under the British Explosives Act, however, this mixing constitutes “manufacture,” and can only be carried out in a properly licensed factory. Consequently Sprengel explosives have not been used in Great Britain, but they have been employed on a considerable scale in the United States, France, Italy and other countries.

For examples of Sprengel explosives see Panclastite, Prométhée, Rack-a-Rock.

SPRENGGELATINE is the German for Blasting Gelatine.

SPRENGSALPETER is a cheap German blasting powder made from sodium nitrate, sulphur and brown coal. It is used in the potash mines.

STABILITE is a name that has been given to trinitro-anisole. It has been tried as a constituent of a smokeless powder, but it belies its title as it is readily hydrolysed with the formation of picric acid. It has also been used by the Germans as a filling for bombs.

*Poudre T is a condensed smokeless shot-gun powder manufactured by the French Government. It is made from guncotton, CP[1], to which 2 per cent. of saltpetre is added, gelatinised with acetone. The dough is pressed into strips which are rolled down to a thickness of 0·15 mm. and cut into small squares of 1·5 mm. side. The powder is then steeped in water to dissolve out the greater part of the potassium nitrate, dried, and finally drummed with a little gum and graphite to make it more progressive. This powder is superior to the other French sporting-powders, but is more expensive. The charge for a 16-bore cartridge is 1·9 grammes.

TELSIT A is a blasting explosive made at the Nobel Works in Switzerland. It consists of ammonium nitrate, nitrated toluene and aluminium powder.

THERMIT is not an explosive, although in some respects it resembles one. It generally consists of a mixture of about three parts oxide of iron with one part of aluminium powder, but other oxides and other metals are sometimes used. When initiated by strong heat in one place a reaction sets in with great evolution of heat and the formation of a white-hot mass of molten iron and slag. It differs from an explosive in that no gas is formed and the reaction is comparatively slow. It is used for filling incendiary bombs and for many industrial purposes.

It is not produced commercially, and, indeed, is too sensitive, but it is sometimes made in the laboratory. It has also been called Angendre’s powder, White German powder, American powder, and Baron and Cauvet’s powder.

WILHELMIT is a German blasting explosive of the Cheddite type. It consists of sodium or potassium chlorate hydrocarbon oil with a flash point not below 30° C., and carbohydrates. For use in coal mines neutral salts are added. It was introduced during the War.

WITHNELL POWDER.—A coal-mine explosive of the Grisounite type made by the Lancashire Explosives Co., which was on the old Permitted List—

Ammonium nitrate

WITTENBERGER WETTERDYNAMIT. See SALIT.

XPDITE is an American coal-mine explosive on the Permissible List. It is made by the Hercules Powder Co., and contains nitroglycerine.

YONCKITE.—A Belgian ammonium perchlorate explosive. The composition has been varied somewhat, and one formula, No. 10, is on the list of Explosifs S.G.P., and consequently is permitted for use in Belgian coal mines. No. 1 is a more powerful explosive used for general blasting.

1.D. The copyright laws of the place where you are located also govern what you can do with this work. Copyright laws in most countries are in a constant state of change. If you are outside the United States, check the laws of your country in addition to the terms of this agreement before downloading, copying, displaying, performing, distributing or creating derivative works based on this work or any other Project Gutenberg™ work. The Foundation makes no representations concerning the copyright status of any work in any country other than the United States.

1.E. Unless you have removed all references to Project Gutenberg:

1.E.1. The following sentence, with active links to, or other immediate access to, the full Project Gutenberg™ License must appear prominently whenever any copy of a Project Gutenberg™ work (any work on which the phrase “Project Gutenberg” appears, or with which the phrase “Project Gutenberg” is associated) is accessed, displayed, performed, viewed, copied or distributed:

This eBook is for the use of anyone anywhere in the United States and most other parts of the world at no cost and with almost no restrictions whatsoever. You may copy it, give it away or re-use it under the terms of the Project Gutenberg License included with this eBook or online at www.gutenberg.org. If you are not located in the United States, you will have to check the laws of the country where you are located before using this eBook.

1.E.2. If an individual Project Gutenberg™ electronic work is derived from texts not protected by U.S. copyright law (does not contain a notice indicating that it is posted with permission of the copyright holder), the work can be copied and distributed to anyone in the United States without paying any fees or charges. If you are redistributing or providing access to a work with the phrase “Project Gutenberg” associated with or appearing on the work, you must comply either with the requirements of paragraphs 1.E.1 through 1.E.7 or obtain permission for the use of the work and the Project Gutenberg™ trademark as set forth in paragraphs 1.E.8 or 1.E.9.

1.E.3. If an individual Project Gutenberg™ electronic work is posted with the permission of the copyright holder, your use and distribution must comply with both paragraphs 1.E.1 through 1.E.7 and any additional terms imposed by the copyright holder. Additional terms will be linked to the Project Gutenberg™ License for all works posted with the permission of the copyright holder found at the beginning of this work.

1.E.4. Do not unlink or detach or remove the full Project Gutenberg™ License terms from this work, or any files containing a part of this work or any other work associated with Project Gutenberg™.

1.E.5. Do not copy, display, perform, distribute or redistribute this electronic work, or any part of this electronic work, without prominently displaying the sentence set forth in paragraph 1.E.1 with active links or immediate access to the full terms of the Project Gutenberg™ License.

1.E.6. You may convert to and distribute this work in any binary, compressed, marked up, nonproprietary or proprietary form, including any word processing or hypertext form. However, if you provide access to or distribute copies of a Project Gutenberg™ work in a format other than “Plain Vanilla ASCII” or other format used in the official version posted on the official Project Gutenberg™ website (www.gutenberg.org), you must, at no additional cost, fee or expense to the user, provide a copy, a means of exporting a copy, or a means of obtaining a copy upon request, of the work in its original “Plain Vanilla ASCII” or other form. Any alternate format must include the full Project Gutenberg™ License as specified in paragraph 1.E.1.

1.E.7. Do not charge a fee for access to, viewing, displaying, performing, copying or distributing any Project Gutenberg™ works unless you comply with paragraph 1.E.8 or 1.E.9.

1.E.8. You may charge a reasonable fee for copies of or providing access to or distributing Project Gutenberg™ electronic works provided that:

- • You pay a royalty fee of 20% of the gross profits you derive from the use of Project Gutenberg™ works calculated using the method you already use to calculate your applicable taxes. The fee is owed to the owner of the Project Gutenberg™ trademark, but he has agreed to donate royalties under this paragraph to the Project Gutenberg Literary Archive Foundation. Royalty payments must be paid within 60 days following each date on which you prepare (or are legally required to prepare) your periodic tax returns. Royalty payments should be clearly marked as such and sent to the Project Gutenberg Literary Archive Foundation at the address specified in Section 4, “Information about donations to the Project Gutenberg Literary Archive Foundation.”

- • You provide a full refund of any money paid by a user who notifies you in writing (or by e-mail) within 30 days of receipt that s/he does not agree to the terms of the full Project Gutenberg™ License. You must require such a user to return or destroy all copies of the works possessed in a physical medium and discontinue all use of and all access to other copies of Project Gutenberg™ works.

- • You provide, in accordance with paragraph 1.F.3, a full refund of any money paid for a work or a replacement copy, if a defect in the electronic work is discovered and reported to you within 90 days of receipt of the work.

- • You comply with all other terms of this agreement for free distribution of Project Gutenberg™ works.

1.E.9. If you wish to charge a fee or distribute a Project Gutenberg™ electronic work or group of works on different terms than are set forth in this agreement, you must obtain permission in writing from the Project Gutenberg Literary Archive Foundation, the manager of the Project Gutenberg™ trademark. Contact the Foundation as set forth in Section 3 below.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.

1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a defect in this electronic work within 90 days of receiving it, you can receive a refund of the money (if any) you paid for it by sending a written explanation to the person you received the work from. If you received the work on a physical medium, you must return the medium with your written explanation. The person or entity that provided you with the defective work may elect to provide a replacement copy in lieu of a refund. If you received the work electronically, the person or entity providing it to you may choose to give you a second opportunity to receive the work electronically in lieu of a refund. If the second copy is also defective, you may demand a refund in writing without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg™ work, (b) alteration, modification, or additions or deletions to any Project Gutenberg™ work, and (c) any Defect you cause.

Section 2. Information about the Mission of Project Gutenberg™

Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.

The Foundation’s business office is located at 809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg™ electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.

Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
