REPORT OF THE SECRETARY 31 



Under the auspices of the Koebling fund, E. P. Henderson, assistant 

 curator of physical and chemical geology, spent several months on 

 Prince of Wales Island, Alaska, for the purpose of collecting speci- 

 mens of epidote and other minerals for which this locality is noted. 

 With the aid of his assistants, Arthur Montgomery, Edwin Over, and 

 C. B. Ferguson, he collected hundreds of fine crystals of epidote, 

 thousands of garnets, and many miscellaneous minerals. In May 

 1937 Mr. Henderson left to attend the Seventeenth International Geo- 

 logical Congress at Moscow. 



In the summer of 1936, Dr. G. A. Cooper, assistant curator of strati- 

 graphic paleontology, with Preston E. Cloud as field assistant, visited 

 Middle Devonian localities in the Middle West to collect fossils and 

 study the Middle Devonian rocks. In June 1937 these two men pur- 

 sued further field work on the Middle Devonian rocks of Michigan, 

 New York, and Ontario. 



Dr. E. O. Ulrich, associate in paleontology, accompanied by K. D. 

 Mesler, of the Geological Survey, collected fossils and studied Lower 

 Ordovician stratigraphy in Arkansas and nearby States. 



C. W. Gilmore, curator of vertebrate paleontology, with Dr. Rem- 

 ington Kellogg, made two short trips to the Chesapeake Bay region to 

 collect cetacean specimens, including several porpoise skulls, previ- 

 ously located by Dr. W. F. Foshag. 



Dr. C. Lewis Gazin, assistant curator of vertebrate paleontology, 

 under funds provided by the Smithsonian Institution, conducted an 

 expedition to the San Juan Basin, N. Mex., during the suimner of 

 1936 to explore the Eocene Wasatch and the Puerco and Torrejon 

 formations of the Paleocene for fossil mammal remains. Besides Dr. 

 Gazin, the party included G. F. Sternberg and Harold Shepherd. 

 They were successful in gathering a representation of the important 

 faunas from these classic early Tertiary horizons, about 500 deter- 

 minable specimens being collected from the Paleocene alone. Later 

 in the season they went to Arizona and explored the Gila and San 

 Pedro Valleys for fossils. 



Dr. R. Lee Collins, of Bryn Mawr, was given a small gi-ant by the 

 Smithsonian Institution for work in the Miocene deposits along Chesa- 

 peake Bay, during the course of which he collected a number of 

 cetacean specimens, parts of a sirenian, and two bird bones. 



MISCELLANEOUS 



Visitors. — For the first time, the number of visitors to the various 

 Museum buildings exceeded the 2 million mark, the total for the year 

 being 2,288,532, which is 314,859 more than the previous year. The 

 351,219 visitors during August 1936 is the largest number ever re- 

 corded for a single month. The attendance in the four Museum build-
