In each trial the use of a self-feeder increased the amount of feed

732. Fattening sheep of different ages. At the Montana Sta- 

 tion 3 Shaw compared the fattening qualities of average western range 

 lambs, 1- and 2-year-old wethers, and aged ewes. Each lot of about 

 50 was fed whole barley and clover hay for 88 days with the fol-
