Some may hesitate about putting fifty chicks in a 

 brooder, but here are the first steps. The brooder is 

 built and the lamp lit. Now fit a piece of newspaper 

 carefully on the floor or top of brooder, and around 

 the chimney. This done, cover the paper with dry 

 sand that is formed of grit or fine stones about one- 

 fourth inch thick. Place a thermometer on the sand 

 near the chimney and place the cover on."

tration, the top of the box being removed to show the 

 interior. The hot .water may be supplied by an ordi- 

 nary stove "water back," or by a coil of pipe in a 

 stove. This is heated by a piece of pipe one inch in 

 diameter, coiled in a stove, holes being cut in the stove 

 for the purpose of admitting pipes. The hot water 

 flows out and the cold water flows in. The floor of the 

 box is made close, with tongued and grooved boards. 

 The cold air enters through tubes reaching to the out- 

 side of the building. It is heated by coming in con- 

 tact with the pipes, and enters into the tubes on the 

 top of the floor, which are two and a half inches high.
