As brand inspector of the association, he was able to recognize on sight 2,700 brands of members from Texas, New Mexico, Oklahoma, Kansas, Nebraska, Colorado, Montana, and Wyoming. In 1918 he became chief inspector for the cattlemen's association at Kansas City. He married Sarah Alpha Grammer, and they had three children.
