not only do the chicks live better in this new brooder but also, 

 according to our experience, those which do live grow better 

 and are thriftier than those raised in the other type of brooder. 

 The second advantage lies in the great saving of labor which 

 is effected by the use of the new brooder. The fact that the 

 brooder never has to be taken away from the house where it is 

 operated means a decided economy.

 CONSTRUCTION OF BROODER. 



In planning this brooder the primary point aimed at was to 

 make it a "fresh air" and a "pure air" brooder. With this idea 

 in mind it was thought advisable to make the wall of the brood- 

 er in some degree permeable to air. To meet this requirement 

 the walls and cover of the brooder are made of cloth. Essen- 

 tially the brooder is a cloth box containing a hover, of the 

 type in which the lamp fumes are conducted outside of the 

 building by an exhaust pipe. 



These brooders are built as a constituent part of the houses 

 which they occupy. Two brooders are placed in each colony
