106 A REVOLUTION IN EGG PRODUCTION 



Fifteen minutes later, when all are in place, the small 'dusk' lamps 

 are extinguished and darkness reigns on the chicken house until the 

 next morning. 



Two weeks after the present lighting system was installed the 

 daily egg output had risen from twenty-six to eighty-three, accord- 

 ing to the owner. Fifty eggs a day are now obtained during the 

 moulting season, in comparison with eleven eggs a day secured under 

 the former artificial lighting conditions." 



This is a very fair article, except for the error in the 

 last line, where it gives the impression that other artificial 

 lights were previously used. 



Judging by the letters received, the "Chicago Tribune" 

 article aroused a general interest. This article, and all the 

 others which the author has seen, with the exception of the 

 one here reproduced from the "Electrical World," show that 

 the subject was treated in either a humorous or sarcastic

The economical importance, of the subject, seems to have

Corroborations of Long Business Day Benefits. 



The first, of whom the author has knowledge, to follow 

 in experimenting with a longer business day was Mr. J- C. 

 Kline, of Congress Park. He seemed to take some interest in 

 accounts of the experiment and its results, but did not ,-eem 

 to get enthusiastic, until he saw the plant in operation at the 

 end of the summer of 1914. He equipped his poultrv house 

 with electric lights, and has received full benefits since in the 

 supply of eggs in the fall and winter. 



The next to follow was Mr. J. W. Allen, of Riverside, 

 Illinois, to whom electricity was not available at the time. 

 The author procured three Air-O-Lanterns, which produced 

 a 300-cp light, with a consumption of one quart of gasoline, 

 for from twelve to fifteen hours. Mr. Allen got one of these 

 lanterns, and after putting the same into use began to receive 

 returns in eggs within three or four days. 



Mr. Maurice L. Newell, a brother of the author, got an- 

 other of these Air-O-Lanterns to try on his poultrv farm in
