cloth curtain is hung around the edge of the broad top- 

 of the drum, forming a hover, into which the chicks go- 

 for warmth. This curtain is "slashed" up every few 

 inches. Openings in the sides of the brooder admit 

 air to the lamp, to the space between the sheet iron 

 and the floor above and also ventilate the brooder 

 chamber. These openings from the brooder chamber 

 can be controlled by corks in very cold weather. The- 

 brooder can be made any size up to three by four feet, 

 which is large enough for seventy-five chicks. It can 

 be heated with an incubator lamp or any good lamp- 

 with No. 2 burner and large oil chamber.
