The differences this year, although indicating a beneficial ef- 

 fect in every instance from the application of nitrate, are com- 

 paratively small except on plot 8. This is doubtless accounted 

 for in large measure by the extreme drought which prevailed 

 during the latter part of the summer. At current retail prices 

 for nitrate during the past season its application did not prove 

 profitable in any instance. 



XI. — Poultry Experbients. 

 The poultry work of the past year has consisted in a repeti- 

 tion of the experiments in feeding for eggs which were carried 

 out during the two preceding years. The general results of these 

 experiments cannot perhaps be better expressed than in the fol- 

 lowing words, quoted from the nineteenth annual report : — 



The experiments liad indicated : first, that, provided fat is abundant in 

 the ration, higli protein content is not essential ; second, tliat, if the fat 

 content of the ration is low, a large proportion of protein in tlie feeds used 

 appears to be much more essential ; and third, that a large proportion of 

 fiber in the ration used is unfavorable to a good egg product. 



The fowls used in the experiments of the past year were, as 

 in previous years, pullets of our own raising. Carefully matched 

 flocks were kept, as in former years, each in a house by itself, 

 all of the houses being precisely similar in general dimensions 

 and construction. The results of the past season's work are 

 confirmatory in every particular of the results previously ob- 

 tained. A somewhat full account of our experiments will be
