Saltpeter

Definition and stakes

Various,  Popular Science Monthly (1914)

“ German militarism realized that two great dangers might arise from these applications of saltpeter. In time of war the importation of saltpeter might be stopped by the navy of a foreign nation, and it might therefore become impossible to manufacture nitric acid and explosives. The feeding of the nation might be interfered with, inasmuch as the soil could not be properly fertilized, and hence could not produce sufficient food-stuff's. Therefore, it became imperative that the nation must become independent of the importation of saltpeter. ”

“ Here are two saltpetre manufactories, in which the saltpetre is procured by boiling the earth dug up among the ruins of the town; saline earth is also dug up in the neighbouring plain; in finding the productive spots, they are guided by the appearance of the ground in the morning before sunrise, and wherever it then appears most wet with dew the soil beneath is found impregnated with salt. The two manufactures produce about three Kantars, or fifteen or sixteen quintals per month of saltpetre, which is sold at about fifteen shillings per quintal. ”

“ Hence, under buildings, especially habitations of men and animals, the salt accumulates, and in times of scarcity it may be collected. In all cases of its extraction from the earth several kinds of saltpetre are obtained, and the usual course is to decompose these by the addition of salts of potash, so as to form from them potash saltpetre, the kind most generally consumed.
In this decomposition of animal remains and the formation of saltpetre the air performs an important part, and the changes it effects are worthy of our attention.
