The average albuminoids in the grains as fed, calculated in this same 

 manner, is as follows for different sections: 



The lowuess of the Pacific slope is purely climatic, as has been found 

 to be the case with all the cereals. In appearance the oats from that 

 section are the finest. The fullness of the husk in the Western States 

 or the plumpness of the grain make this the richest in albuminoids as 

 it is fed. The South is poorest for reasons which have been mentioned. 

 That these figures are entirely dependent on the percentage of husk, 

 and not on peculiarities of the kernel, a study of their analyses will 

 show; for, among 179, only 3 fell below 10 per cent, of albuminoids, 4 be- 

 low 11 per cent., and 12 below 12 per cent., while at the same time 

 only 13 are above 17 per cent., and 23 above 1C per cent.; that is to say y 

 all but 28, or 84.4 per cent., are within the limits of 12 and 16 per cent., 

 a small variation, although the albuminoids are higher in amount than 

 wheat; and as the averages for the different States and sections of the 

 country do not vary fur from 14.3 per cent., with the exception of the 

 Pacific coast, oats cannot be said, as far as the grain itself is cencerued, 

 to be in chemical composition very susceptible to their environment, al- 

 though extremes widely apart are found. 



These were as follows: 



Extremes in composition of kernels of oats. 



The highest percentage of albuminoids was 1.41 per cent, higher than 

 has been found in any other cereal in this country, and the lowest 2 per 

 cent, higher than was found in wheat. 



The analysis of the heaviest and largest, of those having the greatest 

 and least weight per bushel, of those having highest and lowest per- 

 centage of albuminoids and of the smallest in size and in weight per 

 bushel, have been selected as a study of the effect of these contrasts on 

 the chemical composition.
