THE subject of my address is so very broad that I feel it should be modified to read "Twenty-five Years' Progress in High Explosives in America," and so I have confined myself in this way, only referring to European developments when it is necessary to do so to tie them together where they have a bearing on one another .
Black powder, the forerunner of all modern explosives, has undergone little or no change in composition for many years except the substitution of sodium nitrate for potassium nitrate in blasting powders in this country, and the short-lived brown prismatic military powder, made with only partially carbonized wood charcoal and pressed into perforated grains at high pressure to prevent its too rapid combustion in the gun . This powder received its death knell at the time of the Spanish-American War due to the perfection, or rather the introduction, of nitrocellulose smokeless powder for military purposes .
