This folder is part of the papers of William F. Foshag (1894-1956). He was a geologist who specialized in the study of the geology and mineralogy of Mexico. In 1919 he became Assistant Curator at the United States National Museum's Division of Mineralogy and Petrology. From 1929 to 1941 he served as Curator of the Division of Physical and Chemical Geology (Systematic and Applied), and from 1929 to 1948 was also Curator of the Division of Mineralogy and Petrology. From 1948 to 1956, Foshag was Head Curator of the Department of Geology and Acting Curator of the Division of Mineralogy and Petrology. Between 1926 and 1941, Foshag made several collecting trips to Mexico under the auspices of the Smithsonian's Roebling Fund. While serving as a representative of the United States Geological Survey in its cooperative work with the Mexican government, Foshag was able to study the eruption of the Paricutin Volcano in 1943. He made subsequent visits to Paricutin in 1944 and 1945 to observe the volcano. This folder includes a copy of a preliminary report made by Foshag on the Santiago-Tlalchichilpa mining property, situated in Huautla, state of Morelos, Mexico. It includes a part addressed to Mr. Jules Lacaud, Pres. of the Chontalpan Mining Company in Mexico. The report examines the possibilities of exploiting the mining property and gives data on samples of minerals. The following part is correspondence between F. J. Murphy and T. Skewes Saunders, giving opinions on the property. The report, 39 leaves in all, also includes statistics on production and costs of the mine. The report is accompanied by two maps: one, published in 1921,at a scale of 1/10000, is titled "Croquis de los fundos mineros ubicados en el Mineral de Huautla..." the other, published in 1924, is titled "Projection of workings Tlalchichilpa Mine, Huautla, Morelos, Mexico, to accompany report by Morton Weber."
