be sold on a higher priced market than was available 

 for the same fowls in the previous autumn." 



Probably thirty to forty commercial egg farms in New 

 Jersey tested, in 1918-1919, the use of artificial illumina- 

 tion for increasing egg production during the short-day 

 period from September 1 to March 1. Fourteen of these 

 plants reported monthly to the Poultry Department of 

 the State Agricultural College, New Brunswick, N. J., 

 where the records were inspected by Harry R. Lewis, 

 Professor of Poultry Husbandry, and placed in charge 

 of his assistant for compilation. It is expected that a 

 Bulletin telling of the results of these experiments will 

 be published by the State Agricultural College, New 

 Brunswick, N. J. A complete thesis on the subject can 

 be obtained from the Reliable Poultry Journal, Quincy, 

 111. 



The theory advanced is that the use of artificial light 

 in the poultry houses allows the hens more hours for 

 eating, thus giving them as much time for feeding as 

 they would ordinarily have in the spring and the addi- 

 tional food eaten results in increased number of eggs. 



Electric lights are used where they can be had at a 

 reasonable price. Lanterns are made especially for this 

 purpose and some use tubular lanterns. The houses are 

 lighted from 4:30 P. M. until 8 or 10 P. M., and from 

 5 A. M. till daylight.
