PREFACE 



This pamphlet is intended as a preliminary announcement of the 

 results of the year's field expeditions. The scientific results will be 

 presented in technical form in the various other series published by 

 the Institution. 



All the work of the Smithsonian Institution is directed toward the 

 "increase and diffusion of knowledge." In certain of the branches 

 of science in which the Institution has been particularly active — - 

 geology, biology, and anthropology — field work plays an important 

 part by furnishing additional collections for laboratory study and 

 by giving opportunity for first-hand observations .on the ground, so 

 essential in the prosecution of these sciences. 



The photographs presented herein were taken for the most part 

 by the authors of the various articles. 



W. P. True, Editor.
