Sources of Nitrogen Compounds

Abstract

IN the Scientific American for April 21 Prof. T. H. Norton contributes a valuable article under the heading, “American Sources of Nitrogen”. Prof. Norton has given special attention to this important question, and the Department of Commerce published in 1912 an exhaustive report by him on “The Utilisation of Atmospheric Nitrogen.” In 1916 Congress appropriated the large sum of twenty million dollars for the purpose of constructing and organising Government works for the production of nitrogen compounds available for military requirements and for general economic purposes.
