and horny or, as they are sometimes termed, "steely," while the white 

 grains are soft and floury. In Table II are shown the results obtained 

 from two such pairs of grains. 



TABLE II. 



It will be noticed that not only is the " strength " very different 

 but the amount of nitrogen present in the red grains is very much 

 greater than that in the white. The great strength of the red grains 

 may possibly be due to their having been harvested in a slightly unripe 

 condition. The time of harvesting has been shown by Humphries 

 and Biffen* to have a considerable effect upon the strength of a wheat. 



Experiments carried out for many years on the farm of the 

 Royal Agricultural Society at Woburn have shown that manures 

 have but a slight effect on the quality of the wheat grain. The 

 results have varied from year to year, but it would appear that, speaking 

 generally, the use of mineral manures, i.e. potash salts and phosphates, 

 has, as a rule, given a slightly stronger wheat than when nitrogenous 

 manures have been employed by themselves. It is noteworthy 

 that in many years the unmanured plots have given the strongest 

 wheat although the crop has been but small. 



In this country an extensive series of experiments on the effects 

 of various combinations of manures on the wheat crop has been 

 carried out near Benha by Mr. Victor Mosseri. The wheat employed 

 for these experiments was the Hindi variety. Mr. Mosseri kindly 

 gave me small samples from ten of the typical plots and these were
