usually rather short. The heads are small, spreading (fig. 13), and 
usually well filled with slender, yellow kernels. While the weight 
per bushel is sometimes rather low, the percentage of hull is lower 
than in most varieties of oats. The Sixty-Day selection which has 
given the highest 3-year average yield at Moro does not differ in 
appearance from the unselected variety. The principal objections to 
these early oats are the small size of the kernel and the shortness of 
the straw. Because of the short straw it is sometimes difficult to 
harvest them with a binder. When the oat crop is to be cut for

Siberian. — The Siberian is an old European variety. The stock 
grown at the Moro substation was obtained a number of years ago 
from the Ontario Agricultural College, where this variety has been 
a leading one for many years. The Siberian variety ripens at Moro 
about 8 or 10 days later than the Kherson and Sixty-Day. It is a 
tall, rather slender strawed variety, with open heads. The kernels 
are white, long, and slender, but are considerably larger than those 
of the Kherson and Sixty-Day varieties. The average weight per 
bushel at Moro was 34 pounds, which is second only to that of the
