Photograph of cross fencing and water and salt distribution for controlled grazing land. The windmill and 2 fences have converted the 570 acre pasture into 3 pastures of 190 acres each. Livestock are more easily handled and much greater and uniform utilization of grazing land may be had. Sheep traps in the foreground allow release of stock into any desired pasture. TX-60, 317.
