[Apostle John Henry Smith Diary] Salt Lake City
We returned to the City and I was busy about town. I finished paying for my single harness. I paid $17.50 watter tax. I paid G. G. Bywater for fixing my watch. I paid Tom Little three dollars for painting roof to shed. I paid Z.C.M.I. $70.00 in an order. I endorsed a thousand dollars in Kanab Cattle herd stock over to Zion's Savings bank for money borrowed. The evening I spent at home. (4)

About thirty riveters at Z.C.M.I. Shoe Shop go on strike over change in work assignments. While not first collective bargaining strike in Utah, it is first against church business. DESERET NEWS says: "The movement savors too much of the dictatorial style of some of the labor organizations, and should not exist among our people." (5)
