which is also lined with the felt or double blanket. The 
heater is filled with boiling water and put in its place,

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

The heat is admitted to the nest by holes in the shelf. 
Another brooder is shown at Fig. 44. This is a

descends through the floor of the tray into the lower 
part of the brooder, which is hung closely with shett
