stem of the panicle). If these are all about the same length 

 and turned to one side, the variety belongs to the class of 

 side, or ''horse-mane," oats; if the branches are of different 

 lengths and stand out at different angles from the rachis, 



they are of the 

 spreading, or 

 "spr angled," 

 type. The latter 

 is much more 

 common, where- 

 as side oats in- 

 clude only a few 

 varieties, grown 

 generally in the 

 more northerly 

 sections. As with 

 wheat, there are 

 winter and 

 spring oats, ac- 

 cording to their 

 adaptability to 

 fall seeding. 

 Winter oats are 

 much less hardy 

 than winter 

 wheat, and are 

 seldom grown in 

 this country ex- 

 cept in the South- 

 ern and Pacific 

 states. Oats may be divided according to the color of the 

 hull into white, yellow, black (gray or grayish-black) and 

 red (reddish-brown) varieties. The oats commonly grown 

 in the North are white, though black and yellow varieties are 

 sometimes sown ; those grown in the South are red or gray in
