Lewis' rcpdi'ts tluit ])r;ictically all of the Cdiiiniercial jionltry 

 raisers of New Jersey are making use of lights. 



.lust w hat the a])])r(jved ])ractice regarding the use of lights 

 will finally l>e, cannot yet he foreseen. Among the several 

 methods in use two appear to give the most promise. These 

 ai-(.' referred to as "morning lights" and "evening lunch." 



Moniiii;/ LigkU. — l.cw'is found morning lights superior to 

 evening lights or to a combination of morning and evening 

 lights. The best time for starting the lights was found to be 

 4 A.^i. running them until sun-u]). In connection with 

 morning lights grain should be fed four times daily in a deep 

 litter, viz., 4 and N A.ir., 1 p.m. and just before dusk. The 

 heaviest feedings should be given at dusk and at 4 a.m. 

 The early morning feed may be scattered in the litter at night 

 after the birds are on the j^erch. 



Evening Lttnch. — Wiih the so-called evening lunch method 

 the birds are allowed to go to perch at dusk, and come down 

 at daylight. The lights are turned on, however, for one 

 hour at 8 p..m. during which time the birds are given a heavy 

 feeding of grain with plenty of fresh water available. This 

 method reduces the cost of lighting, as compared with tither 

 methods, gives the birds longer hours of rest and does not 

 re(|uire the use of dimming devices as when evening lights 

 are used; for after the first few days tlie birds will have all 

 returned to their jierches by nine o'clock at which time the 

 lights are turned off. 



A gTa])hic presentation of I ewis's- results with (itiO ])ullets 

 without lights, 5110 ])ullets with morning lights and 100 pullets 

 given an evening lunch mav' be seen in Figiu'e 178. Tlie 

 comparative profits per bird for a period of nine months w ere 

 S3.30, $5.07 and $5.48 respecti\-ely for the three grou];)s. 



Details of Li(jh1iii(j /''/■(/(■/(ct'. — Follow ing Lewis, when 

 lights are used it is of the greatest imjjortance that tlie stock 

 should be graded and flocked according to age, condition and 

 laying qualities. Pullets of different ages or jnillcts and hens 

 should always l)e kept in ditferent flocks.
