I started from Montrose on my mission to England. My health was so poor I was unable to go thirty rods to the river without assistance.
After I had crossed the river I got Israel Barlow to carry me on his horse, behind him, to Heber C. Kimball's, where I remained sick till the 18th. I left my wife sick, with a babe only ten days old, and all my children sick and unable to wait upon each other.
