other groups, with pale yellow, brown, and black spikes 

 respectively, in all of which the glumes of the side spike- 

 lets are divided and not grown to the spikelet axis. Of 

 these the first group is cultivated in Arabia and Abyssinia 

 and the other two in Abyssinia only. 



128. Distribution in North America. Barley is a 

 comparatively small crop in the United States and Canada, 

 although third in rank of the small cereals. It is also 

 much more irregular in its distribution than wheat and 

 oats. While California and Minnesota each produce 

 over 30 million bushels annually, three-fourths of the 

 states produce each less than two million bushels. All of 

 Canada produces 48 million bushels, or about 21 per cent 

 of the North American crop. It seems sufficient for the 

 present purpose to designate only about six North 

 American barley districts: (1) The Northeastern or Six- 

 row barley district, (2) the Southern or Winter barley 

 district, (3) the Northwestern Plains or Two-row barley 

 district, (4) the Southern barley district, (5) the Western 

 Intermountain barley district, and (6) the Pacific Coast 

 barley district. These correspond in a general way to the 

 wheat and oat districts. 



129. Northeastern or six-row barley district. In this 

 district are included all of New England, the middle 

 states to the southern boundary of Pennsylvania, and the 

 northern states southward almost to the Ohio River, and 

 middle Missouri, and westward to about the meridian of 

 96 in Kansas and nearly to the Missouri River in North 

 and South Dakota; the Maritime Provinces, Quebec, 

 Ontario, Manitoba, and Saskatchewan to a line through 

 Regina and Saskatoon. 



This district may be called the six-row barley district, 

 as that kind of barley seems generally best adapted, with
