Plate II. 



Fig. I. — Prairie-Dog Plot. 



The grass here is noticeably shorter and thinner than that shown in Plate I, and the ground 

 is easily visible in several places, as a result of grazing hy prairie dogs. 



Fig. 2. — Cattle-Grazed Plot. 



Very little grass is in evidence outside the fenced plots, where the forage is freely grazed by cattle.
