The United States Department of Agriculture has for a number of years been conducting investigations in connection with grazing problems. The benefits to the vegetation of " rest periods " and the " alternation of pastures " have been advocated for some years,1 and as early as 1895 rotation grazing was discussed as follows: Clearly, then, if the grazing quality of the ranges is to be improved, they must be so treated that the nutritious native species of grasses and forage 1 Smith, Jared G.
