on Long Island to test the comparative merits of methods of 

 application of fertilizers and the efficiency of the various forms 

 of nitrogen. These tests showed little difference in the efficiency 

 of organic nitrogen from dried blood as compared with inorganic 

 nitrogen from nitrate of soda. It was noticed, however, that 

 where there was sufficient rainfall, there was a more rapid growth 

 of vines from the nitrate of soda. As to the manner of applica- 

 tion, there appeared to be a small difference in favor of distri- 

 buting the fertilizer in rows. The advantage was slight, how- 

 ever. These tests ratify much more extended experiments made 

 some years ago in showing that when fertilizers are used in excess 

 of 1,000 lbs. per acre, there is not a corresponding increase of 

 yield and either practically no profit or a loss. 



During the past sixteen years, there have been maintained on 

 the Station farm, fertilizer experiments having for their object 

 a comparison of certain methods of maintaining soil fertility. No 

 reports have yet been made of this work, but after harvesting a 

 crop of 1913, the results for this long period of time will be made 

 public. 



POULTRY PRODUCTION. 



While but little has been published in recent years from the 

 Poultry Department of the Station, work has been going on 

 steadily chiefly along breeding and nutrition lines. This work 

 is of such a nature that it is necessary to continue it for a long 

 period of time in order to get results that are reliable and upon 

 which conclusions can be based.
