CEREAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 383 
In 1913 the yields were low. The highest yield, 13.2 bushels 
per acre, was obtained from the 2-peck rate. In 1914 the highest 
yield, 11.9 bushels per acre, was obtained from the 4-peck and 5-peck 
rates. In 1915 the highest yield was 34.9 bushels per acre, obtained 
from the 7-peck rate, though the yield from the 5-peck rate was only 
slightly lower. The results to date show that a thin seeding of 2. to 
4 pecks per acre has given the best average yields in the 3-year period. 
DATE-OF-SEEDING EXPERIMENT. 
A date-of-seeding experiment with the Svanhals barley has been 
conducted at the Cheyenne Experiment Farm during the 3-year 
period, 1913 to 1915, inclusive. Plats have been sown April 15, 
May 1, and May 15 each year. The annual and average yields 
obtained from this test are shown in Table XXIII.

Yields in 1913 and 1914 were low, with a slight advantage for the 
early seeding. In 1915 the yields were much higher, the May 15 
seeding giving the highest yield, 40.3 bushels per acre. The average 
yields favor early seeding, between April 15 and May 1. 
EXPERIMENTS WITH FLAX. 
Flax is one of the common farm crops in eastern Wyoming, being 
grown quite extensively on the newly broken prairie. However, flax 
is not grown as extensively as results indicate that it should be. 
VARIETAL EXPERIMENTS. 
Fourteen varieties of flax have been grown on the Cheyenne Experi- 
ment Farm for a period of three years and two additional varieties for 
a period of two years. The annual and average yields obtained from 
these 16 varieties are shown in Table XXIV. 
Tn 1913 the flax varieties were sown in tenth-acre plats on breaking 
at the rate of 15 pounds per acre. The seed was not well distributed 
_ by the drill, but fair stands resulted. The summer was rather dry, 
_ the precipitation in May and June ‘being below normal. A fair 
| growth was made and the yields ranged from 4.3 to 7.4 bushels per
