the day was far gone. Went with Peale, he on a mule and I on 
a pony, to work up the Geology of Spring Canon. Passed through 
the Canon and a mile above to examine a coal bed, which had 
been worked to some extent. Pound the owner in his bank in- 
specting. He took us to his ranch and gave us a superb dinner, 
good coffee, bread, butter, ham and apple sauce. We gathered 
fossils on the ridge and returned to camp through the Canon. 
The party was joined by William Blackmore, the English 
traveler and museum founder, and we set out for our explora- 
tions, I on a nice little pet horse of my own choosing which 
required a vast deal of beating and spurring to enable me to 
keep up with Hayden and Blackmore on their fine mounts. The 
riding was rapid and we scurried from valley to valley and moun- 
tain to mountain, examining the rocks and I sketching whatever 
seemed of particular interest, and in the evening we camped on 
a creek near its entrance to the Yellowstone River. We camped 
next near Boetlers Ranch, occupied by the two Boetler brothers, 
the only settlers so far in the valley. The younger brother 
became our hunter and kept us in deer and elk meat during the 
trip/ The next camp was at Cinnabar Mountain, and I made 
sietch.es of the "Devil Slide" (see the 1872 Report) and the great 
ranges north of the river. 
We visited Bridger Mountain and found at its base creta- 
ceous fossils, and on the twelfth a number of us set out on a 
journey to Mystic Lake. I started from Camp leading a yellow 
pacj£ mule. At the Suttlers we overtook Burak and the Odometer.
