observe that the crops grown in Colorado were still characterized by the 

 source of the seed.

These wheats were the richest in albuminoids of any that had been 

 examined up to that time in this country. Since then the hard spring 

 wheats of the Northwest have been found to be more nitrogenous, but not 

 comparable in their size or yield. 



The second year, twelve varieties, grown from seed supplied by the 

 Department of Agriculture, were analyzed. After one year, that is to 

 say, the first year's growth in Colorado, they were found to have all in- 

 creased in size, and instead of an average weight of 3.402 grams per 

 hundred grains, they weighed 4.299 grams. As regards the percentage 

 of albuminoids, where the seed wheat was low in nitrogen there was a 

 gain, but as half of the varieties contained originally more albuminoids 

 than the average Colorado grain, there was a drop in six of the twelve 

 specimens toward the average. For example, a seed having 16.11 per 

 cent, of albuminoids, the crop fell to 14 91 per cent., while one having 

 only 9.65 rose to 12.15 per cent. From these facts, and the analyses of 

 the previous year, the conclusion was drawn that the conditions in 

 Colorado were suited to the production of a grain containing about 13 

 per cent, of albuminoids. 



This was undoubtedly the case at the time. In the two following 

 years, however, these conditions have been somewhat modified. 



In the third year, 57 varieties were examined, 28 of which had been 

 analyzed before in 1881. A loss of albuminoids occurred in all but 4 

 cases, and a loss of weight in all. The average for the year was
