on the summit of Mount Uyuca and to other areas in the departments 

 of Morazan and El Paraiso. While collecting in the cloud-forest area 

 of the San Juancito Mountains, Mr. Morton was the guest of the 

 New York and Honduras Rosario Mining Co. Another longer trip 

 was made to Lake Yojoa, in the departments of Santa Barbara and 

 Cortes, and to the mountains near Siquatepeque, Comayagua. On 

 May 31 Dr. E. H. Walker departed from Washington for Okinawa 

 in response to a request made to the Pacific Science Board, National 

 Research Council, by the Department of the Army for the assignment 

 of a botanist to make a 4-months' study of the flora of the Ryukyu 

 Islands. 



The program of investigations undertaken by the department of 

 geology and financed for the most part from income of the Walcott 

 bequest, involved field work in Alaska, California, Utah, Wyoming, 

 Colorado, Texas, Virginia, Tennessee, and Panama. Dr. George S. 

 Switzer completed field studies relating to the genesis of iron ores in 

 the Iron Springs district of southwestern Utah. During the early 

 part of the summer of 1950, Dr. G. Arthur Cooper and W. T. Allen 

 continued field work on the Wolfcamp formation, the lowest portion 

 of the Permian beds in the Glass Mountains of west Texas. Later 

 in the summer Dr. Cooper visited Blacksburg, Va., where, accom- 

 panied by Dr. B. N. Cooper, of the Virginia Polytechnic Institute, he 

 spent several days collecting Ordovican fossils from the Catawba 

 Valley section. Subsequently a thick sequence of Ordovician rocks 

 was examined by Dr. Cooper and Dr. R. B. Neuman, of Gatlinsburg, 

 Tenn., during a brief visit to the west side of the Great Smoky Moun- 

 tains. Under a contract between the Office of Naval Research and 

 the Smithsonian Institution, Dr. A. R. Loeblich, Jr., assembled a 

 large collection of living Arctic foraminiferal faunas near Point Bar- 

 row, Alaska, during the summer of 1950. With the assistance of Max 

 B. Payne, of Bakersfield, Calif., Dr. Loeblich, late in April and in 

 May 1951, obtained foraminiferal samples from the Moreno and 

 Panoche formations in Fresno County, Calif., and with Dr. Edward 

 Bailey, of the U. S. Geological Survey, in the Franciscan series in 

 Santa Clara County, Calif. 



In the summer of 1950, Dr. D. H. Dunkle and F. L. Pearce made 

 careful stratigraphic collections of fossil plants, invertebrates, fishes, 

 and mammals in the Green River shales of Colorado, Utah, and 

 Wyoming. Early in 1951, Dr. C. L. Gazin and his assistant, F. L. 

 Pearce, returned to the interior of western Panamd to continue with 

 the investigation of the Pleistocene fauna of that area. Most of the 

 skeletal remains excavated belonged to the giant ground sloth, 

 Megatherifwm^ but, in addition, fragmentary remains were found of a 

 peccary, a giant armadillo, and a bird. The field work in Panamd
