Average composition of American barleys (hulled), arranged by States. 



The changes are merely such as one would expect from the removal 

 of the fibrous hull. The percentages of albuminoids, fiber, and earbhy- 

 drates are increased, that of ash and water diminished. The results are 

 merely of value to serve as a comparison of this cereal in its hull less 

 condition with the other cereals in a similar state. 



Our investigations as a whole seem to prove that, while at present 

 Canadian barleys are superior to those grown in the United States, the 

 result is due more to a lack of understanding of the proper localities 

 and methods of cultivation than in any obstacle in the way of extending 

 the production to an extent to do away with our dependence on importa- 

 tion. Field experiments are now most desirable as a means of deciding 

 upon the best varieties and methods as soon as a study of the climatic 

 conditions shall enable us to select those portions of the country best 

 suited to this cereal. In time, no doubt, California, whose climate in 

 many parts is well adapted to the growth of barley for malting pur- 

 poses, will make itself felt if, as appears probable, the quality of her 

 barleys in the market answers to the expectations raised by laboratory 

 examination. 



ANALYSES OF OATS, BARLEY, AND RYE IN DETAIL. 



In our first report several analyses of wheat were published in which 

 the carbhydrates were separated into their proportions of sugars, starch, 

 and gum, and the albuminoids into those soluble in alcohol of 80 per 

 cent, strength and those insoluble. In the Annual Keport of the De- 

 partment for 1878 several analyses of corn were presented in the same 

 way. For comparison with these results, which are of interest, several 

 have been made of oats, barley, and rye :
