Another point not mentioned above in connection with these industries is the training of chemists, chemical engineers and the building up of plants for the manufacture of chemicals, all of which are necessary sources of supply for wartime needs. Chemists are needed in the field, in the laboratory and in manufacturing plants. The greater their number, the more efficiently can these materials be handled, and since chemicals as such will probably cause more than 50 per cent of all casualties in future wars, their value is almost unlimited.
Instead of trying to ameliorate the ravages of war, let us turn every endeavor towards abolishing all war, remembering that the most scientific nations should be the most highly civilized, and the ones most desirous of abolishing war. If those nations will push every scientific development to the point where by the aid of their scientific achievements they can overcome any lesser scientific peoples, the end of war should be in sight.
However, we can never be certain that war is abolished until we convince at least a majority of the world that war is disastrous to the conqueror as well as to the conquered, and that any dispute can be settled peacefully if both parties will meet on the common ground of justice and a square deal.
CHAPTER XXVI
THE FUTURE OF CHEMICAL WARFARE
The pioneer, no matter what the line of endeavor, encounters difficulties caused by his fellow-men just in proportion as the thing pioneered promises results. If the promise be small, the difficulties usually encountered are only those necessary to make the venture a success. If, however, the results promise to be great, and especially if the rewards to the inventor and those working with him promise to be considerable, the difficulties thrown in the way of the venture become greater and greater. Indeed whenever great results are promised, envy is engendered in those in other lines whose importance may be diminished, or who are so short-sighted as to be always opposed to progress.
Chemical warfare has had, and is still having, its full share of these difficulties. From the very day when chlorine, known to the world as a benign substance highly useful in sanitation, water purification, gold mining and bleaching was put into use as a poisonous gas, chemical warfare has loomed larger and larger as a factor to be considered in all future wars. Chlorine was first used in the cylinders designed for shipping it. These cylinders were poorly adapted for warfare, and made methods of preparing gas attacks extremely laborious, cumbersome and time-consuming.
It was not many months, however, until different gases began to appear in large quantities in shells and bombs, while the close of the war, 3½ years later, saw the development of gas in solid form whereby it could be carried with the utmost safety under all conditions—a solid which could become dangerous only when the heating mixture, that freed the gas, was properly ignited.
While some of the chemicals developed for use in war prior to the Armistice have been made known to the world, a number of others have not. More than this, every nation of first class importance has continued to pursue more or less energetically studies into chemical warfare. These studies will continue, and we must expect that new gases, new methods of turning them loose, and new tactical uses will be developed.
Already it is clearly foreseen that these gases will be used by every branch of the Army and the Navy. While chemicals were not used by the Air Service in the last war, it was even then realized that there was no material reason why they should not have been so used. That they will be used in the future by the Air Service, and probably on a large scale, is certain. The Navy, too, will use gases, and probably on a considerable scale. Thus chemical materials as such become the most universal of all weapons of war.
Some of the poisonous gases are so powerful in minute quantities and evaporate so slowly that their liberation does not produce sufficient condensation to cause a cloud. Consequently, we have gases that cannot be seen. Others form clouds by themselves, such, for instance, as the toxic smoke candle, where the solid is driven off by heating, while still others cause clouds of condensed vapor. This brings the discussion into the realm of ordinary smokes that have no irritating and no poisonous effects.
