 which is also lined with the felt or double blanket. The 

 neater is filled with boiling water and put in its place, 

 wrapped in a piece of blanket to retain the heat and 

 moderate it. A nest, covered with a sheet of paper, 

 which can be removed when soiled, is put on the shelf. 

 A pasteboard box, upon half-inch cleats, makes a good

 The heat is admitted to the nest by holes in the shelf. 

 Another brooder is shown at Fig. 44. This is a 

 larger and shallower box, having a tray in the upper

 heater rests ; a lid is made to cover this tray. This heat 

 descends through the floor of the tray into the lower 

 part of the brooder, which is hung closely with shcrt
