EXI'EKIMEXTS WITH WI>TEK-WHEAT SELECTION?. 
About 60n selected heads of Turkey, Kharkof. and Crimean wheats 
were sown in head rows in the fall of 1908. Practically all of these 
were sown in G'J-foot rows the following year and many of them for 
several years following. The selections giving the highest yields in 
the nursery were later grown in plats. About 35 of the>e selections 
were sown in plats in the fall of 1910, but they failed on account of 
drought. A few selections were again sown in plats in the fall of 
1912 and these produced a crop in 1913. 
Several additional selections which had shown high yields in the 
nursery experiments were sown in plats in the fall of 1914. The 
better strains were continued in the plat- in 1916 and a few in 1917. 
The 191S crop was entirelv winterkilled. The vields are shown in
