CEREAL INVESTIGATIONS AT THE NEPHI SUBSTATION. 37 
winter survival was then determined by dividing the number of 
plants growing by the number of seeds planted. 
The number of plants maturing was determined also. This 
number seldom differed from the number of plants surviving. 
Occasionally, however, a weak plant would fail to mature. For this 
reason it was necessary to make the second count. If the second 
count were not made, the possibility of error would be enhanced 
when the average number of heads to the plant was being determined.

SPRING WHEAT VARIETIES. 
The test of the value of the different sizes of seed of spring wheat, 
as stated before, was conducted during only one season, in 1909. Two 
varieties were used, one durum, Kubanka (C. I. No. 1440), and one 
common, Spring Ghirka (C. I. No. 1517). The durum variety, 
Kubanka, has light-brown or yellowish chaff and beards and large, 
hard, clear-amber kernels. The common variety, Spring Ghirka, 
is beardless, and it has a white chaff and medium-sized, hard, red 
kernels. Some difficulty was experienced in obtaining the desired
