PREFACE 



In several of the sciences of chief concern to the Smithsonian 

 Institution, namely, geology, hiology, and anthropology, field work 

 plays an important part. To collect specimens in little-known regions, 

 to fill gaps in the National Museum collections, and to record data 

 that can be obtained only on the ground, a number of expeditions go 

 out each year from the Institution, some to nearby States, others to 

 remote corners of the earth. A few of these expeditions are financed 

 wholly from Smithsonian funds, but for most of them support comes 

 from private sources or through cooperation with other agencies or 

 individuals. 



This pamphlet, which is printed annually by the Institution, serves 

 as a preliminary announcement of the purposes and results of the 

 year's expeditions and field work. Later, after the material has 

 been studied by the specialists at the Institution and its branches, the 

 scientific results are embodied in one of the various Smithsonian 

 series of publications. 



The photographs were made for the most part by the field workers 

 themselves.
