Conditions varied so greatly from season to season that yearly data 
can not safely be averaged. In the fall of 1918 dry weather was 
continuous and conditions were so unfavorable that no seeding of any 
sort was attempted previous to October 1. Rains came about Ovto- 
ber 25, and second seedings were put in at this date, the late seedings 
being made on November 15. In 1919 fall conditions seemed some- 
what more favorable, and the earliest seedings were made on Sep- 
tember 15 and second and third seedings on October 15 and November 
15. The early promise did not materialize, however, and no rains 
in any quantity came before November 15. As a result of these 
unfavorable seasonal conditions emergence of both crops occurred in 
midwinter. In the fall of 1920, on the other hand, some rain came 
comparatively early, and while not of enough volume to promote the 
best growth and development the plants from the first seeding date 
made some growth before the others emerged. These light rains 
later largely evaporated, so that the later seedings also emerged 
during midwinter. 
Remembering that for the 1919 crop rains in quantity came at the 
time of the second seeding, for the 1920 crop at the time of the late 
(third) seeding, and for the 1921 crop with the first seeding, the data 
indicate that under very dry conditions nothing is gained by seeding 
in the dry soil before fall rains. This is the most that can be deduced 
from the results of these experiments. 
The data covering the rate of seeding are given in Table 34. 
Because of the same unfavorable conditions applying to the date-of- 
seeding results, the results on rate of seeding are equally unsatis- 
factory and the averages equally invalid.
