used. Plats were sown at the rates of 4, 6, 8, and 10 pecks each year. 
Tn addition, the 2-peck rate was used in 1909 and the 12-peck in 1910, 
1912, and 1913. The test was conducted on fallow land in 1909, 
1910, and 1912, while in 1913 it was on land which produced corn 
the previous year. In 1909 and 1910 single tenth-acre plats were 
sown at each rate. In 1912 and 1913 the test was replicated, three 
fiftieth-acre plats being sown at each rate. 
Table XVIII shows the annual and average yields obtained in the 
rate-of-seeding test with oats in 1909, 1910, 1912, and 1913. .

In 1909, which was a favorable year, the higher rates of seeding 
gave the better yields, though the differences between the 6, 8, and 
10 peck rates were small. In 1910, a very dry year, the best yields 
were obtained from the 4-peck and 6-peck rates. The yields obtained - 
from the 10-peck and 12-peck rates of seeding little more than equaled 
the quantity of seed which was sown. In 1912, another dry year, 
there was little variation in the yields which were obtained, though 
the 6-peck rate produced slightly more than any of the others. In 
1913, a favorable year, the yields obtained from all the rates of seed- 
ing were practically the same. 
The average yield for the four years from the 4, 6, 8, and 10 peck 
rates shows little variation, though the.figures favor shghtly the 6- 
peck rate. The thickly sown plats ripened earlier than those sown 
at the lower rates, while the yield of straw was usually less. In 
very dry years thin seeding is to be preferred. On the other hand, 
in favorable seasons fully as good yields and slightly earlier maturity 
will be obtained from thick seeding. It seems probable that 6 pecks 
is about the best rate for early varieties, such as the Sixty-Day and 
Kherson. 
NURSERY EXPERIMENTS WITH OATS. 
About 100 heads each of the Sixty-Day and Kherson oats were 
selected in 1908 and grown in head rows in 1909. Im addition a 
number of selections of the Sixty-Day made at the Highmore sub-
