AMERICAN WHEAT AND CORN. 



CONCLUSIONS DERIVED FROM THE DATA. 



The analyses in the preceding tables when combined with those pre- 

 viously published modify to a certain immaterial degree the average 

 composition of the wheat of the whole country. The few scattered anal- 

 yses from the Eastern States change the averages for those States very 

 slightly, the greater number of specimens coming from Ohio, Minnesota, 

 Dakota, and California, localities which were not represented before, or 

 at most indifferently well ; and from Colorado, where wheats from the 

 same farm have been examined for three consecutive years. 



OHIO. 



The wheats from this State were grown on the farm of the Ohio State 

 University, near Columbus, Ohio. A number of them were the result 

 of experiments on the yield and other qualities of the grain, which have 

 been carried on by the farm superintendent, Mr. W. Brotherton, for 

 three years. 



The crop of 1883 averaged, it is said, about 30 .bushels per acre. It 

 was not, however, entirely plump, " owing to a wet^priug succeeded by 

 dry weather before ripening," and the weight per bushel was therefore 

 light, about 57 pounds. The fact that the grain was shriveled was very 

 likely due to a lack of ability to fill the floury portion with its full quantity 

 of starch, and the relative percentage of nitrogen is therefore higher than 

 would be found in a well-developed grain. 



From the data derived from the experiments above mentioned, the 

 following averages have been published by Mr. Brotherton :
