VARIETAL TESTS. 
The acre yields in bushels obtained in varietal tests of wheat at 
Brookings. Highmore. Eureka, and Cottonwood are shown in Table 
III. The results for eight years (1905 to 1912) are given for Brook- 
ings and Highmore and for four years (1909 to 1912) in the ease of 
Eureka and Cottonwood. These yields were produced without fer- 
tilizers and without systematic rotation, the method being strictly 
comparable to that in use by the majority of farmers. Any gain in 
yield over the average for the State may be ascribed to the producing 
power of the variety, to well-cleaned seed, and to good tillage rather 
than to fertilization or good rotation methods.
