In 1912 a tenth- acre plat was sown and about 50 per cent survived the winter. This plat yielded at the rate of 14,2 bushels per acre. In 1913 several plats were seeded at different rates. The stands and fall growth were good on aU plats, but the crop entirely winterkilled. In 1914 three twentieth-acre plats were sown to winter emmer at different rates. A fair stand was obtained and the winter survival was high. The average yield of the three plats was about 20 bushels per acre. Winter emmer has not survived the winters as well as winter wheat and the yields have been much lower. Winter emmer evidently is not adapted to conditions on the high western plains. The average.

Winter emmer is drought resistant, but it is not nearly so hardy as the Crimean group of winter wheats. The data available indicate that Black Winter emmer is a doubtful crop in eastern Wyoming and growing it should not be encouraged at present. SPRING EMMEK. White Spring emmer has been grown at Archer in each of the three years, 1913 to 1915, inclusive. In 1913 a tenth-acre plat was sown. The stand obtained was too thick and the growth was short. The plat yi(!ld(3d at th(! rate of busliels per acre. In 1914 a tenth-acre fuUow pljit was sown. On this plat the stand was very thick und the growth was short, yielding at th(^ rate of bushe
