rowcii 1.150 tons per acre. Plot 3, which was manured 

 with II combination of l^one and potash in amounts named, 

 and nitrate, gave yields of hay 2.228 tons and rowen (two 

 crops on a part of the plot) 1.219 tons per acre. The aver- 

 age yield of the entire area for this year is 6,510 pounds, 

 hay and rowen l)oth included. The field has now been 

 twelve years in grass, and during the continuance of the 

 present system of manuring, since 1893, has produced an 

 average product, hay and rowen l)otli included, of 6,G15 

 pounds per acre. The plots, when dressed with manure, 

 have averaged 6,817 pounds per acre; when receiving bone 

 and potash, 6,62G pounds ; and when receiving ashes, 6,371 

 pounds. It will he noticed that, while the general average 

 for this year, including all the plots, falls below the general 

 average for the entire period, the average for this year of the 

 two plots receiving bone and potash and ashes is above the 

 general average for the entire period. It will be remem- 

 bered, however, that these plots have this year, in addition 

 to the usual amounts of bone and potash and ashes respec- 

 tively, received a light dressing of nitrate of soda. It is i)os- 

 sil)ly this ditference in treatment which has produced the 

 results just pointed out. 



Poultry Experiments. 

 The experiments of the past season have, as in previous 

 years, been devoted to the study of methods of feeding, as 

 affecting egg-production. The only experiment the results 

 of which it is proposed to report at the present time is one 

 having for its object the determination of the relative merits 

 of the system of giving a mash in the morning, as compared 

 with the system of giving it late in the afternoon. 



General Conditions. 

 Barred Plymouth Rock pullets, raised on the scattered 

 colony })lan, divided into two lots as equally matched in 

 weight and development as possible at the beginning of the 

 experiment, were employed. Twenty such pullets with two 

 cockerels were put into each house. Our houses are de- 

 tached, and include a closed room for nests and roosts, 10
