"A more recent miracle occurred at the Wells Stake Welfare Tannery some years ago where hides of animals were tanned into leather. On regular workdays, the hides were removed from the vats and fresh lime placed in the vats, after which the hides were returned to the lime solution. If the hides were not turned on holidays, they would spoil. But the change was never made on Sunday, and there were no spoiled hides on Monday. Explained J. Lowell Fox, the supervisor of the tannery at the time:
" “This brought a strange fact to our minds: holidays are determined by man, and on these days just as on every week day, the hides need to have special care every twelve hours. Sunday is the day set aside by the Lord as a day of rest, and He makes it possible for us to rest from our labors as He has commanded. The hides at the tannery never spoil on Sundays. This is a modern-day miracle, a miracle that happens every weekend!” (Handbook for Guide Patrol Leaders, Salt Lake City: The Church of Jesus Christ of Latter-day Saints, 1964, p. 37.)"
