"Numerous accounts of Zion’s Camp demonstrate that one or both sides of the lesson—the millennial and the extortionary— bore immediate fruit in Joseph Smith’s colleagues’ improved treatment of animals. Echoes of the lesson can also be heard many years later in statements by Brigham Young, as well as by leaders who did not participate in Zion’s Camp, such as Joseph F. Smith and George Q. Cannon. In fact Cannon, a first counselor to Brigham Young, John Taylor, Wilford Woodruff, and Lorenzo Snow, was instrumental in advocating the humane treatment of animals and promoting a 'Humane Day' that was observed in LDS Sunday Schools every spring from 1897 to 1918. Cannon was interested in more than emulating non-LDS groups like the American Society for the Prevention of Cruelty to Animals; as Aaron R. Kelson notes (quoting Cannon), his efforts were rooted in the millennial conviction that 'the time will come when man and animals which are now wild and ferocious will dwell together without hurting each other . . . But before this day comes men will have to cease their war upon the animals, the reptiles and the insects . . . When man becomes their true friend, they will learn to love and not to fear him. The Spirit of the Lord which will rest upon man will also be given to the animal creation—man will not hurt nor destroy, not even tigers and lions and wolves and snakes, and they will not harm him—and universal peace will prevail.”
