By Gideon S. Dodds 



During the summer of 1906 the University of Colorado sent out a 

 scientific expedition to the northeastern part of the state, under the 

 direction of Junius Henderson, curator of the museum. The expedition 

 started from Boulder on June 7 and spent thirty days in the field. The 

 party, consisting of four persons connected with the departments of Biol- 

 ogy and Geology, traveled by wagon and visited parts of Boulder, 

 Larimer and Weld Counties. The total distance covered was over 

 350 miles. 



The purpose of the expedition was to cover considerable ground and 

 to do work of a preliminary nature rather than to make exhaustive 

 collections. In the field each man had his part of the work to do. In 

 this way it was possible to collect a considerable variety of materials. 

 Probably the most valuable part of the collections made are the fossil 

 specimens from various localities. The plant collections are also impor- 

 tant. During the trip a large number of small lakes were visited and a 

 considerable collection of mollusks made. A small collection of bird
