EXPLORATIONS AND FIELD-WORK OF THE SMITH- 

 SONIAN INSTITUTION IN 1914 



(With One Plate) 



During the year 1914 explorations and field-work were continued 

 in various parts of the world under the direction or with the 

 cooperation of the Smithsonian Institution. The more important 

 are here reviewed, chiefly in the words of the participants therein. 

 They include geological, zoological, botanical, anthropological, and 

 astrophysical lines of investigation. 



Three government branches of the Institution are represented in 

 this report : the National Museum, although having no funds set 

 aside for this purpose, avails itself wherever possible of opportunities 

 to engage in natural history investigations and to add to its collec- 

 tions ; the Bureau of American Ethnology is occupied largely with 

 field-work among the Indians themselves, the annual report of that 

 Bureau covering this work in detail ; and the Astrophysical Observa- 

 tory, in connection with its regular work of studying the physical 

 properties of the sun and their effects on the earth, undertakes expe- 

 ditions in this country and abroad for purposes of observation and 

 investigation. 



These various lines of field-work have tended to increase knowledge 

 in the sciences and have added much valuable material to the col- 

 lections of the National Museum and the Bureau of American 

 Ethnology. The Institution was prevented from participating in 

 many other expeditions only by its limited funds. 



GEOLOGICAL EXPLORATIONS IN THE ROCKY MOUNTAINS 



In continuation of his previous geological researches in the Rocky 

 Mountains of Canada and Montana, Dr. Charles D. Walcott, Secre- 

 tary of the Smithsonian Institution, spent a week during the field 

 season of 1914 at Glacier, British Columbia, where he assisted Mrs. 

 Walcott (nee Mary M. Vaux) in measuring the flow of the Illecille- 

 waet and Asulkan glaciers, photographs of which are shown in 

 plate 1 and text figures 1 and 2. 



From Glacier, Dr. Walcott proceeded to White Sulphur Springs, 

 Montana, for the purpose of studying the ancient sedimentary Pre- 

 paleozoic rocks of the Big Belt Mountains. These explorations 

 were made on the eastern and southern slopes of this range, and
