Description of Birds. — For the purpose of these experiments, 

 four lots of chickens were chosen, taken as hatched from the 

 incubators, without any attempt at selection, namely, (1) thirty 

 white Wyandottes, (2) thirty Faverolles, (3) thirty Buff Orping- 

 tons, and (4) thirty cross-bred (consisting of fifteen Houdan-Buff 

 Orpingtons and fifteen Indian Game-Buff Orpingtons). 



It was intended to have again included Faverolle-Buff Orping- 

 tons, the cross that succeeded so well in 1904, but none were 

 available at the time the experiment was commenced. 



The particulars of the experiments with each lot are given 

 •separately. 



Experiment No. i. — White Wyandottes. 

 The gross consumption and cost of each class of food are 

 •shown in Table II., and the average weekly weights and 

 increases, with atmospheric conditions, in Table III.
