his work on the flora of Colombia. Members of the staff of the 

 Colombian Institiito BotJinico accompanied Mr. Killij) on various 

 excursions. Most of the time was spent in the Pacific lowlands, the 

 regions visited including Gorgona Island, Bahia Solano, the Dagua 

 Valley, and the upper San Juan River region in the heart of the 

 Choco. With Cali in the Cauoa Valley as a base, several trips were 

 made to the Western Cordillera. A few days were spent along the 

 Quindio Trail, in the Central Cordillera, where special attention was 

 given to the wax palms. Accompanied by A. H. C. Alston, of the 

 British Museum (Natural History), Mr. Killip explored the region 

 about Villavicencio in the Orinoco drainage basin ; excursions were 

 also made from Bogota to various points in the Eastern Cordillera. 

 Altogether, about 2,600 numbers of plants were collected, these in- 

 cluding many duplicates. 



Geology. — Dr. K. S. Bassler, Head Curator (vf Geology, during a 

 vacation trip to England in August and September 1938, made cer- 

 tain researches in the well-known southern England fossil areas 

 extending from Cornwall on the west to the Chalk Cliffs at Dover. 

 Excursions were made to various parts of the English lowlands, with 

 brief intervals spent at the British Museum (Natural History) to 

 study and check formation and locality occurrences of Paleozoic 

 crinoids. The field studies included particularly the Subcarbon- 

 iferous limestone area near Bristol, a Mesozoic locality at Lyme 

 Regis, and various chalk outcrops south and east of London. The 

 most valuable result of the trip was the information obtained for 

 more accurate labeling of the National Museum's collection. 



In July 1938 Dr. G. A. Cooper, Assistant Curator of Stratigraphic 

 Paleontology, went to Strouclsburg, Pa,, and there met Dr. Bradford 

 Willard, of the Pennsylvania Geological Survey, for paleontological 

 work at various localities. They spent a week around Stroudsburg 

 and in southeastern New York examining Devonian strata. Later 

 Dr. Winifred Goldring, State paleontologist of New York, joined 

 Dr. Cooper in a study of detailed sections of the Hamilton Group at 

 Port Jervis and at various other localities between that city and 

 Albany, N. Y. At Catskill, G. H. Chadwick joined the party. Tlie 

 object of the trip was to learn the sequence of strata in the Hamilton 

 of eastern New York and to discover if possible the true top of the 

 Hamilton in the Catskills southwest of Albany. All but the latter 

 objective was attained. At the end of the New York work Dr. 

 Cooper joined Dr. Willard in east-central Pennsylvania to study 

 sections in the Hamilton and Tully strata. The entire work re- 

 quired about 6 weeks. 



On May 2, 1939, Dr. Charles Butts and Dr. Cooper met Dr. Josiah 

 Bridge, of the Geological Survey, in Bristol, Va., and from there 

 continued to Montevallo, Ala. After studying Ordovician sections in
