Davis, David L., Journal, in Chronicles of Courage, 8 vols. [1990-97], 4:241-42.
I remained at Wyoming City, Nebraska, but a short time. Before the week was out, I was driving a five yoke team for a man by the name of John Judge Kerr, a freighter for the Salt Lake merchants. The work was altogether strange to me, but I soon got used to it and won for myself the reputation of being the fastest yoker in trains. We traveled without any accident and very little sickness and reached our desired home on the sixth day of October, 1864.
