Sperry, Charles, Autobiographical sketch [n.d.], 2-3.
The emegrants going to Oregon traveld on the south side of the river while we traveld on the north side until we came to Laremy [Laramie]. We traveld some distance up the south side then crost over a ridge and struck the sweete water [Sweetwater] and traveld up that streem for some distence. Then crost the back bone and pased the Pissific [Pacific] Springs. After that all the water ran west. We had a nomber of stampeeds of cattle on the way. They would git scared of something brake out of the correll and run off. At one time about 25 head broke away and went back to the Masary [Missouri] river about 150 miles. One of our oxen was with the bands. He came on the next year. Sometimes the whole trane of 50 or 100 wagons would stampede then evry boddy would have to look out for themselves to keepe from being run over.
We got into the Salt Lake valley with 5 oxen, 3 cows, 2 wagons. Near the first part of Oct. 1847 we arrived.
