A patch of white Mediterranean seed from Department, second year's 

 growth. 



Serial No. 2768, 33 heads, weighing 37.5 grams and yielding 567 grains, 

 or 75.2 per cent., weighing 28.197 grams, of which 461 were sound and 

 106 sprouted in the stack. 



The sound weighed per 100, 4.875 grains ; the sprouted, 5.400, and 

 contained albuminoids; the sound, 12.08 per cent.; the sprouted, 13.48. 



A field of Fultz, from a different portion of the same farm, gave among 

 14 average heads, weighing 391 grains: 



Among the Fultz sports were found : 



2772 1 Bearded brown chaff 4.184 11.03 



2772* i Smooth brown chaff 3.9951 14.00 



The results show that where the divisions have been made on marked 

 characteristics there is a difference in composition ; but that for aver- 

 ages from the same field, even where some physical differences could be 

 noted, there is little variation on analysis. Three of six samples from 

 a field of Fultz were exactly alike in their percentage of albuminoids, 

 another was only .18 per cent, different, or practically the same, wh'ile 

 the rakings from the field were, as might be expected, low in albumi- 

 noids. One selected head also fell below the average composition for 

 some unexplained reason. In this field of Fultz, therefore, there seems 

 to be sufficient evidence to give us confidence in our results. 



The next samples were taken from a shock of wheat, and the grain 

 was found on preparation for analysis to have sprouted. It was there- 

 fore divided into two parts. The grain which sprouted was the heavier 

 and best developed and contained the most albuminoids. This is also 

 the case in another field of Fultz on the same farm, where an average 

 sample was divided into large and small grains, the larger having the 

 most albuminoids. That this is not by any means always the case, bow- 

 ever, it seems fair to believe from our experience with high relative pro- 

 portion of nitrogen in specimens of shriveled wheat from other parts 

 of the country. These kernels were none of them shrivelled ; on the 

 contrary, plump, and that some were merely more vigorous than others 

 must stand as an explanation. 



Sports or stragglers in the same field of Fultz were found to vary 

 very largely from each other and a little more than the different-sized 

 grains of Fultz. This must be attributed to peculiarities in the variety 

 and their different ability to assimilate nitrogen under the circumstances.
