132 ANNUAL RECORD OF SCIENCE AND INDUSTRY. 



ra, where rich collections rewarded their efforts. Returning 

 from this excursion, they proceeded early in August to Fort 

 D. A. Russell, near Cheyenne, and from that point made a 

 trip, accompanied by a detachment of the Fifth Cavalry, un- 

 der Captain Montgomery, into Northern Colorado, and thence 

 to Antelope Station, where extensive collections were made. 

 From this point they moved to the north branch of the Platte 

 River, near Chimney Rock, and again returned to Fort Rus- 

 sell by way of Horse Creek. Continuing their labors, they 

 started westward to Fort Bridger, with an escort from the 

 Thirteenth Infantry, and examined the eastern Uintah Moun- 

 tains, and the region along the Green and White rivers, and 

 other main tributaries of the Colorado, and after an absence 

 of about eight weeks returned to Fort Bridger. 



Thence a portion of the party went to California, and visit- 

 ed the Yosemite Valley, while others proceeded to Denver in 

 November, and then to Fort Wallace, in Kansas, where their 

 explorations for the season were concluded. The amount of 

 material brought in by both these parties, the movements of 

 which overlapped each other to a certain extent, may be con- 

 sidered as the most important and valuable ever made in a 

 single season in the United States; and as they will be sub- 

 mitted to the most accomplished specialists in the United 

 States for investigation, we may look with confidence to the 

 final reports of the results as likely to clear up a great deal 

 that is at present perplexing and obscure in the geology and 

 natural history of the country. 



EXPLORATIONS OF PROFESSOR POWELL. 



It may be remembered by some of our readers that Con- 

 gress, at its last session, made an appropriation of $12,000 for 

 completing the survey of the Colorado of the West, under 

 Professor Powell. A proposition is now before that body 

 for an additional appropriation of $12,000 to enable the pro- 

 fessor to undertake and complete a topographical and geo- 

 logical survey of the valley of the Green River. As the 

 equipment now on hand, and used in the surveys of the Colo- 

 rado, will answer for the work on the Green River, and as 

 this last-mentioned valley must be traversed before the labors 

 on the Colorado can be finished, it is urged that the work can 

 be accomplished at a much less cost than that of the original
