atmosphere as this. Over trails all but impassable, up 

 hill and down dale, most laboriously we advanced and at 

 last, on the i8th, camp was made in a Cottonwood 

 grove on the banks of the Snake River in Jackson's Hole, 

 near the foot of the Grand Teton. 



Here some days were spent, during which an ascent 

 of the Grand Teton was made. On the 20th three of us 

 began the ascent. That night was spent on the shore of a 

 small lake at about 9,500 feet. The next morning the 

 more precipitous slopes were scaled, but at about 11,000 

 feet further progress was stopped by a frightful chasm 

 which entirely cut off all communication with the spire- 

 like summit that still towered above us. The descent 

 was made more rapidly, and at nightfall on the 21st we 

 were again in camp, loaded down with the collections of 

 that and the preceding day. 



This camp marked the most distant point reached by 

 the expedition and on the afternoon of the 22nd the 

 return journey was begun. The route lay up the Gros 

 Ventre River, up Bacon Creek and over the divide separat- 

 ing it from Green River. On reaching Green River we 

 camped for twenty-four hours, after which we proceeded 

 to Cora postofifice on New Fork. At this point the route 

 took a general south-east course, skirting the foot hills on 

 the west of the W^ind River range. The following 

 streams were crossed in succession, viz: New Fork, 

 Boulder Creek, East Fork, Silver, Willow, and Muddy 

 Creeks, the Big and the Little Sandy. This brought us 

 to South Pass City, the oldest mining camp in the Wind 

 River Mountains, thirty miles south of Lander. 



At this point, on September i, the writer found it 

 necessary to sever his connection with the expedition and
