This report deals essentially with the occurrence of manganese on the Ingram-Howe ranch, 3 miles north of Shumla, where several test pits were dug and the manganese sampled for analyses. Included also are brief descriptions of the occurrence of manganese on the Babb and Mills ranches along the Pecos River. The purpose of this investigation was to locate manganese deposits, determine their mode of occurrence, tonnage, and whether or not the deposits could be mined on a commercial basis.

Previous investigations of manganese in the Shumla area were made during World War I and prior to that war by several local prospectors, who dug many test pits. A report on the manganese at Shumla and Feely was made by Roberts and Nash in 1918. Much of the preliminary work, such as the supervision of the digging and sampling of 15 test pits on the Ingram ranch, was done by Mr. George H. Shafer, Assistant Project Supervisor, Work Project No. 18927. The writer wishes to express his appreciation to Mr. John Ingram and to the other property owners who were very cooperative in aiding this investigation. The writer is indebted to Dr. V. E. Barnes for his many helpful suggestions, and thanks are also due to Mr. William N. McAnulty, State Supervisor, Statewide Mineral Resources Survey.
