Physical properties of oats Contiaued. 



From the preceding tables it appears that in the North white (includ- 

 ing in this color yellow), black and white, and black oats are principally 

 sown, while in the South varieties of the red rust proof are almost en- 

 tirely grown. 



In the North the crop is put in in April or May and harvested in July 

 or August. In the South it is sown from November to January and 

 harvested in May or June. 



The difference in appearance is marked betw.een the crops of these 

 two sections of the country. The Southern oats are large, light, awned 

 varieties, of reddish brown color, with inflated husks not nearly filled 

 by the kernel. The Northern grain is smaller, more compact, not often 

 awned, and with the husk in the better samples well filled out. 



Notwithstanding these characteristics, we learn from averages of the 

 results that the size and weight of the Southern clean kernel is rather 

 larger than the Northern. Its fluffy husk, however, makes them lighter 

 oats in weight per bushel. 



The averages have been calculated for various sections as follows : 

 The Northern States include all north of Maryland and Kentucky, 

 together with Missouri, Montana, and Dakota ; the Southern, all south 

 of these; and the Pacific slope, Colorado, Nevada, New Mexico, Wash- 

 ington Territory, Oregon, and Utah; the Atlantic slope consists of 

 the States east of the Ohio river and the Gailf; the .Western States, of 

 those west of this line, excepting those on the Pacific slope. The same 

 classification is preserved with the other cereals.
