The Iron Ration: Three Years in Warring Central Europe

by George Abel Schreiner

That much was done in that field is true enough. But a great deal of scientific effort resulted in no more than what, for instance, synthetic rubber has been.

The first thing the German scientists did at the outbreak of the war was to perfect the system of a Norwegian chemist who had succeeded two years before in condensing the nitrogen of the air into the highly tangible form of crystals.

Many are under the impression that the process was something entirely new and distinctly a German invention. I have shown that this is not so. Even the Norwegian cannot claim credit for the invention as in itself new. His merit is that he made the process commercially possible.

The thing was a huge success. The British blockade had made the importation of niter from overseas impossible. There is no telling what would have happened except for the fact that the practically inexhaustible store of nitrogen in the air could be drawn upon. It kept the Central Powers group of belligerents in powder, so long as there was vegetable fiber and coal-tar enough to be nitrated. Incidentally, some of the by-products of the nitrogen process served in good stead as fertilizer. The quantity won was not great, however.

I am not dealing with war as such, and for that reason I will pass by the many minor inventions of a purely military character that were made, nor would it be possible to do more than a cataloguing job if I were to attempt to refer here to all the innovations and substitutions that were undertaken as time went on.

Science multiplied by three the store of textiles held in the Central states at the outbreak of the war. This was done in many ways and by various means. Take cotton, for instance.

That almost anything could be converted into explosives by nitration has been known ever since Noble made nitroglycerine a commercial product. Any fat or fiber, even sugar, may be nitrated. That generally we use glycerine and cotton for the purpose is due to the fact that these materials are best suited for the process.

But the fats that go into glycerine, and the cotton that becomes trinitrocellulose, could be put to better use by the Central states. In a general way coal-tar took the place of the former, and wood pulp that of cotton. That meant a tremendous saving in food and clothing.

I remember well the shiver that went through Germany when Great Britain declared cotton to be contraband. The Entente press was jubilant for weeks. But any chemist familiar with the manufacture of explosives could have told Sir Kendall that he was too optimistic. It was known even then that birch pulp and willow pulp made most excellent substitutes for cotton, if the process, or "operation," as the thing is known technically, is suitably modified. Coal-tar explosives were already un fait accompli.

Having attended to that little affair, the German scientists turned their attention to the winning of new textiles. There was the nettle in the hedges. Anciently, it had been to Europe what cotton was to the Mexico of the Aztecs. Times being hard, the nettle, now looked upon as a noxious weed fit only for goose fodder, was brought into its place. Very soon it was in the market as a textile, which often aspired to as imposing a name as "natural silk," a name the plant and its fiber well deserve.
