nitrogen intake was lowered below normal when these substances were fed.

 Bui. 217 {1913), pp. 64, figs. 48). — This bulletin treats of the following subjects: 

 Poultry house construction, egg production, feeding methods, incubation, rearing

 with short notes on poultry work in Ireland, Scotland, England, and Denmark. 



The results of 3 feeding trials, involving 745 pullets, indicate that the aver- 

 age cost per dozen eggs produced ranges from 11.16 to 13.08 cts., the average 

 cost of feeding each bird per month from 10.06 to 10.88 cts., the average grain 

 consumption from 5.66 to 6.2 lbs., and the average milk consumption from 7.1 

 to 7.8 lbs. It was further found that where beef scrap was fed in a hopper 

 or when the birds could eat all they desired, the Leghorns and Rhode Island 

 Reds did much better than the Orpingtons; that with all 3 breeds buttermilk 

 produced the most and the cheapest eggs; and that no animal feed in all in- 

 stances gave the best eggs for hatching and the lowest egg yield. On a no-meat 

 ration the feather eating habit was developed by the Leghorns, and to a limited 

 extent by the Rhode Island Reds, but not by the Orpingtons.
