Returned sore footed to camp, getting a drink of ehoiee milk 
as we passed the Ranche. 
In the morning we cut our way through the mesquites 
and reached the second Canyon of the Yellowstone in the after- 
noon, Camped near the river on the hank of a creek. Bruno 
and the Indian Officials came to camp and took Mr. Blackmore 
away to the Mission* 
July Twenty-f if th: In the morning I started off with 
the Doctor up the Canyon a short distance and then up a ravine 
through the brush and rocks to the. mountains, passed a pretty 
lake and had a shot at an antelope. Ascended a peak 2200 
feet, passed do?m through a deep valley, across a creek by a 
wigwam of saplings and a beautiful little lake, around the 
Devil’s Slide , down a very steep precipice to camp at the base 
of the great slide. The Doctor had come in ahead of me and 
hurried me up to get my dinner and go with him to make a section 
of a geological outcrop. We ascended to the ridge, I went much 
higher than he and came down between the two wonderful walls of 
rock of the Devil’s Slide, ten or twenty feet thick and one 
hundred or one hundred and fifty feet in height. It was dark 
before I got to camp. 
July Twenty-sixth: In the morning, I stopped behind 
the train to make drawings, found some fossil ammonites, lost 
my hammer and hurried forward to the hot springs. Turned up 
Gardiners River but had some difficulty in finding camp. Peale, 
Ganett and Brown were all day and all night on Electric Mountain
