The United States is the world's most self-sufficient nation in respect to the minerals needed for peace-time or wartime industrial production, it is stated today in the current Harvard Business Review, by Paul M. Tyler, Chief Engineer, Nonmetal Economics Division, United States Bureau of Mines.
"Given adequate stock piles of tin, high-grade mica, radio quartz, industrial diamonds, and a half-dozen deficient ferroalloying minerals and certain tropical plant materials, we could be virtually independent of overseas imports for years at a time," Mr. Tyler said.

His review covered not only eleven materials classified as strategic, but also six minerals of importance, but capable of more ready procurement, and a comprehensive list of the other minerals essential to war-time operation.
