How does Osborne Russell use imagery in Osborne Russell's Journal of a Trapper: Edited from the Original'?

Examples of Imagery:

"A large fire was soon blazing encircled with sides of Elk ribs and meat cut in slices supported on sticks down which the grease ran in torrents The repast being over the jovial tale goes round the circle the peals of loud laughter break upon the stillness of the night which after being mimicked in the echo from rock to rock it dies away in the solitary [gloom]." pg. 86

"Near where I was encamped was a small stream which ran from a spring about a 100 paces distant and emptied into the river the water was a little more than blood warm. The Beaver had taken the advantage of the situation Damed it up at the Mouth and built a large lodge on the bank at sunrise I discovered three of them swimming and playing in the water." pgs. 151-152
