Phosphate deposits in the western United States have been the subject of considerable discussion in the last decade, and during the last few years much interest has been aroused in them. Phosphate was first discovered in this area in 1889, but it was not until 1906 that the United States Government took active interest in the study of these deposits. The investigation by the government of the occurrence of western phosphate was begun by Weeks and Ferrier (10), and later carried on by others. On December 9, 1908 the western phosphate reserve was created and many acres of land were withdrawn from all kinds of entry. In the summer of 1909 two parties were detailed by the United States Geological Survey to examine lands withdrawn from public entry.
