selections from the Sixty-Day have slightly exceeded the parent 
variety in average yield in the years they have been grown. 
There is some objection to these oats by farmers because of the 
yellow color and small size of the kernel. As oats are commonly 
grown in Montana for feed rather than to sell, the yellow color is 
not objectionable. Because of the thin hulls, these varieties have a 
larger proportion of kernel to hull than the larger types of oats. 
The Sixty-Day is being increased at the Judith Basin substation. 
About 2.000 bushels have already been distributed throughout the 
dry-land areas of the State, and the results obtained seem to indicate 
that for these lands the Sixty-Day variety is the best.

MIDSEASON VARIETIES. 
Of the varieties of oats that have been tested at Moccasin. 13 can 
be classed as midseason in maturity. The Swedish Select is the only 
one in this group that has been grown in the entire seven years. This 
variety has a 7-year average yield of 46.5 bushels, which is 15.9 
bushels lower than the 7-year average yield of the Sixty-Day. Other 
typical varieties of this group are the Danish, Lincoln, and Silver- 
niine. All these are more suitable for growing under irrigation than 
on the dry farms in Montana. 
The varieties of the midseason group have tall, coarse straw and 
large, rather broad grain. They are from a week to 10 days later 
in maturing than varieties of the early group, 
LATE VARIETIES. 
All the late varieties which have been grown are side oats. The 
White Russian, White Tartarian, and other late varieties have not 
produced good yields at Moccasin except in 1909. In that year they
