Mormon History, Jun 12, 1847. Saturday.

[William Clayton Journal] ...At a quarter to 12 we halted after crossing another large ravine, having travelled 7 1/4 miles, over a sandy, barren prarie...During the halt Brother [Albert] Rockwood called upon the brethren to help fix another ravine immediately west of us, many turned out and it was soon done. James Case and S[tephen] Markham went to the river opposite here to see if it could be forded. They waded their horses over and found the water about 4 feet 6 deep in the channel and the current very swift and of course it could not be forded with loads in the wagons, but the loading would have to be ferried in the Boat. They made a report of this kind on their return to Camp and about the same time Brother Chessley came down from the brethren ahead and reported their progress and the nature of the crossing place &c. A number of the brethren, in company with Elder Kimball and Chessley went to the river opposite the Camp to decide whether to cross here or go on. Brothers Markham and Case again went over, but it was finally concluded to go up to the other ferry...The brethren concluded that a raft would be of no use on account of the swiftness of the current. The Missouri company offered to pay them well if they would carry their company over in the Boat and a contract was made to do so for $1.50 per load, the brethren to receive their pay in flour at $2.50 per hundred. They Commenced soon after, and this evening finished their work, and received their pay mostly in flour, a little meal and some bacon. They have made $34 with the cutter all in provisions which is a great blessing to the Camp inasmuch as a number of the brethren have had no bread stuff for some days. During the afternoon yesterday one of men of the Missouri company undertook to swim across the river with his cloths on. When he reached the current he became frightened and began to moan. Some of our men went to him with the cutter and arrived in time to save his life. The Missouri company seem to feel well toward us and express their joy at having got across the river so soon . . .
