BULLETIX 242, U. S. DEPARTMENT OF AGBICtTLTTTBE. 
CORX AT DALHAET. 
Six crops of corn have been grown at the Dalhart station. In three 
of the years under study grain was produced, while in the other three 
years nothing but stover was produced. The best yield was obtained 
in 1914, when optimum seasonal conditions for the production of this 
crop prevailed. Listing has been productive of the highest average 
yield of grain, but it is thought that this may be due to the fact that 
the listed plat occupies such a position on the farm that it sometimes 
receives considerable run-off. Because of the low cost of this method 
of preparation it gives the greatest profit. Summer tillage is the 
most costly method of seed-bed preparation : consequently it returns 
rather a low profit, although it insures a good yield of fodder every 
year. The difference between the average yields by spring and fall 
plowing is very slight.

CORX AT AMARILLO. 
Seven crops of corn have been grown at Amarillo. Tex., and. 
although only one complete grain failure is recorded, the yields of 
four years were so low that husking would have been impracticable 
in farm practice. The 1908 yields varied from 14.7 to 27.6 bushels 
per acre. If such yields could be obtained consistently, the growing 
of corn in this section would be justified. The average yields, how- 
ever, are not sufficient to cover the cost of production. All methods
