my heavenly father for my boy and pray that he will spare and preserve his life and that of his mother and so order it so that we may soon meet again." This hymn signified the difficulties and faith involved in the Mormon migration to the west and was popular among pioneer Latter-day Saints. In a 1951 article for the Improvement Era, Heber J. Grant wrote that he specifically requested that congregations sing the fourth verse about accepting death and not end with the third verse. The hymn appears in the Protestant New Church Hymnal with the third verse changed to refer to a heavenly resting place rather than one in the far west. Clayton's hymn "When First the Glorious Light of Truth" also appeared in LDS hymnals, He also wrote words for "A Deluded Mormon" and "The pioneers at length are come." The Roadometer and The Latter-day Saints' Emigrants' Guide Clayton, along with Orson Pratt and Appleton Milo Harmon, created a novel design for a wooden odometer for use on wagons, also called a roadometer. Clayton was assigned to record the number of miles the company traveled each day. One day, Clayton personally counted the revolutions of a wagon wheel and computed the day's distance by multiplying the count by the wheel's circumference. Clayton asked Pratt to develop a design for a wagon odometer. It consisted of a set of wooden cog wheels attached to the hub of a wagon wheel, with the mechanism "counting" or recording by position the revolutions of the wheel. The apparatus was built by the company's carpenter Appleton Milo Harmon. The wagon-mounted odometer helped Clayton measure accurate distances between landmarks, starting from Council Bluffs and going to the Great Salt Lake. After returning to Winter Quarters, Clayton prepared and published The Latter-Day Saints' Emigrants' Guide. Clayton's guide was the first to scientifically measure the distances on the overland trail and was in high demand. Life after immigrating to Utah Clayton served a second mission in England starting in September 1852. He was briefly president of the Sheffield and Lincolnshire Conferences before being released in April 1853 and returning home to Utah in October of the same year. Once settled in Utah, Clayton continued to maintain church records and also participated in public and private business activities. He became an auditor for Utah Territory, as well as recorder of marks and brands, holding both positions
