NOTES ON EXPERIMENTS WITH POULTRY. 



Edward Brown, F.L.S., and Cecil A. Flatt. 



The following notes describe two experiments which have 

 been made on the College Poultry Farm, Theale, to test new 

 methods, one originating in America and the other in the 

 Transvaal. 



Chicken Brooders without Heat. 



Where chickens are reared artificially, brooders of one 

 form or another are necessary, and these involve expense for 

 purchase and heating, together with constant attention. 

 Practically one brooder is required for every fifty chickens 

 raised in any season, but, if successful, the result is well 

 worth the labour and expense. An American inventor, how- 

 ever, — Mr. E. W. Philo — claims that artificial heating is 

 unnecessary, and that if the chickens are accommodated in 

 a properly constructed brooder, lamps can be dispensed with. 

 In this he is supported, so far as the warmer months of the 

 year are concerned, by Professor C. D. Davenport, of Cold 

 Spring Harbour, N.Y., who recently stated that his experi- 

 ments had led him to the conclusion that heatless brooders 

 could be entirely used in America after the end of March. 



The construction of the "Philo" brooder is simple, consist-
