more in width, usually limited by steep bluffs, being in no place of a 

 marked canon form. The walls become less well defined near the mouth, 

 and when the creek at last approaches the White, it is through low 

 terraces, upon a broad, open bottom-land, the largest in the entire 

 course of the White, with perhaps the exception of Agency Park. An 

 attempt was made some years ago to start a colony in this valley, but 

 for some reason the attempt was a failure. The ground is now within 

 the limits of the reservation for the Ute Indians. 



Passing down the river through this valley, we entered the canon of 

 the White, already referred to, and connected the work with that done 

 before from the mouth of Evacuation Creek. Then turning up the river 

 we completed the remaining small unworked portions along its borders, 

 and reached the agency October 11, having in forty -eight working days 

 completed the topography of 3,800 square miles of country, making in the 

 course of the work 41 main topographical stations, besides 16 auxiliary 

 ones, and travelling 1,000 miles within the district.

On the 12th of October our party left the White Eiver agency to 

 return to the East, and choosing the route through the Middle Park 

 instead of that via Eawlin's Springs, avoided the expense and trouble 

 of railway shipment. This route formed a most pleasant line of march, 

 abounding as it did in wood, water, and grass, three elements of com- 

 fortable camping much lacking in the other route. The extra time 

 between the agency and Cheyenne consumed only two days. 



Dr. Endlich and Mr. Dickerson left the party at Boulder City, while 

 I remained with it one more day and dismissed the men and animals at 

 the upper crossing of the Big Thompson Eiver, that they might proceed 

 directly to Cheyenne, while I completed a few hundred square miles on 

 the plains bordering the mountains. I was engaged ten days in work- 

 ing the topography of this additional area, living at the towns and 

 settlements as I came to them. The topography was very simple, and 

 I was enabled to cover 800 square miles in the ten days, riding about 

 350 miles, and closing the season's work at Denver about the last of 

 October.
