by changes in temperature. If stored in damp bins it becomes 

 musty, and as odor is one of the factors which influence the market 

 value, dampness and mustiness should be avoided. Dampness is 

 also likely to injure the germination of the grain, either for malt- 

 ing or for seed. When barley is well cured before thrashing and is 

 stored in cool, dry bins, it passes through the sweating process and 

 remains bright, clean, and sweet. If the grain becomes damp in 

 any way it should be shoveled over several times or changed to an- 

 other bin in order to dry it thoroughly. A prominent grain grower 

 in Maryland dries damp or poorly cured grain by forcing a cur- 

 rent of air through it from the bottom of the bin by means of a fan 

 driven by a small engine. The fan is usually run for a day or 

 two, but after the current is established the fan can be stopped. 

 This method avoids the necessity of rehandling the grain when it 

 becomes damp. 



Varieties. In recent years there has arisen a considerable 

 rivalry between two-rowed and six-rowed barleys, and there has 

 been much discussion as to the relative merits of these two classes 

 of barleys. It is well known that the two-rowed barleys are gen- 

 erally used in Germany and are considered much better than the 

 six-rowed varieties. In this country the six-rowed varieties have 

 been in favor. This is no doubt partly owing to the fact that the 

 six-rowed barleys have until recently been given more attention 

 by the farmers, and have therefore obtained a foothold in this coun- 

 try. It is only recently, after a thorough investigation of many 

 barley varieties, that the difference in adaptation of these two groups 

 of barleys to different portions of the country has been ascertained. 

 This natural adaptation of the two groups to different areas appears 

 to clear the situation nicely, at least from the agricultural stand- 

 point. As there seem to be good arguments from the commercial 

 standpoint for the production of either class of barleys there is ap- 

 parently no good reason why the farmer should not cultivate the 

 particular barley which gives him the best acre yields. 



In the largest barley-growing district, the six-rowed barleys, 

 Manchuria, Oderbrucker, and Odessa, do best in Minnesota, Wis- 

 consin, Illinois, Iowa, and Nebraska, while in North Dakota and 

 South Dakota the two-rowed varieties, such as Hannchen, Swan 

 Neck, Chevalier, and Hanna, give better results. Six-rowed barley 

 is principally grown in western New York and in Michigan, Ohio, 

 and Indiana. In Kansas, Oklahoma, Texas, and the Southern 

 States generally the most profitable variety to grow is the six-rowed 

 Tennessee Winter. In the high altitudes of the Rocky Mountain 

 States hooded barley is the most profitable type. In Utah and 

 Idaho the six-rowed type, both spring and winter, gives the best re- 

 sults, Utah Winter being the most profitable variety. In the Pacific 

 States the six-rowed varieties, Bay Brewing and California Feed, 

 are the most common, although some excellent barley of the two- 

 rowed varieties, Chevalier and Hanna, is also produced. 



The hooded and hull-less barleys have proved successful in 

 the semiarid regions of the West, where they are superior to any.
