The experiment was started in 1943 and concluded at the end of the grazing season in 1945. Because of difficulties encountered in securing and erecting fences, the experiment did not start at the beginning of the first grazing season. Only, one replicate was used in the first year and measurements of gains were obtained for' the period of July 19 to October 11; In 1944 grazing commenced on April 24 and ended August 14. Extremely dry weather during,July and August of this year caused the streams providing water in three of the lots to dry up. Because of this emergency condition, the experiment had to be terminated before the end of the grazzing season. In 1945 grazing began on April 1 and terminated October 3. This grazing season was characterized by no > unusual conditions and iwas considered to be a normal grazing ■; season for this section.
