Grazing distribution was not a major problem in these 2 pastures. Perhaps the problem is not important in pastures no larger than these, in poor to fair condition, on relatively level terrain, and with young cows. Earlier studies (Ares, 1936 and 1953 and Valentine, 1947) indicated that grazing use declined with increased distance from water. In those studies, the pastures were uniformly good or excellent condition black grama. In our study, there were a variety of species available and distance from water was unimportant if the cattle were interested in grazing a species that occurred 3 mi. from water. Data presented by Norris (1953) also indicated that the location of a palatable species at a distance from water was responsible for better grazing distribution. This information suggests that better grazing distribution may be obtained by growing palatable species at the opposite side of the pasture from the water development. LITERATURE CITED ARES, F.
