Field work.- Several parties collected and studied in the field.

Mineralogy and Petrology.- In August 1959 curator Switzer made a collecting trip to various western localities, including the uranium mined in the vicinity of Grants, N. Mex., the borate deposit at Boron, Calif., and the copper mines at Butte, Mont. Material collected was added to the Roebling collection.

Vertebrate Paleontology.- Dr. Peter P. Vaughn made several trips to West Virginia to collect Upper Paleozoic vertebrates. In October Dr. Vaughn joined Dr. G. E. Lewis of the U. S. Geological Survey on an expedition of a few days to study the Cutler formation in San Miguel Canyon and Rico regions, Colorado, as background for a joint description of the Cutler fauna.
