Science and research. Mineral prospecting. Speed in metallurgical analysis, to match the rapidity with which the nation arms itself, is possible through use of the spectrograph, a marvelous new machine used for study of materials through measurements of the arc of light they emit when heated. The aluminum and magnesium industries, steel companies and foundries use it for quick study of metals. Mines use it for exploration. The spectrograph will yield an analysis of seven elements in fifteen minutes determination, which would require up to four hours by old chemical methods. Three students in defense training courses at a famous mining-engineering school listen as an instructor shows them how the machine operates. Golden, Colorado
