asbestos paper, having an opening at the 
top corresponding to the diameter of the 
pail about five inches below its top. In the 
bottom of this box is placed any one of 
several commercial lamps made for the pur- 
pose of keeping the water from freezing. It 
will be necessary to bore several holes in the 
sides of the box, two or three inches above 
the floor. 
This water container, both summer and 
winter, is placed near the front of the building 
under the open front, principally to locate 
it in a place where the least litter from the 
floor will be scratched into it, since usually 
the birds face the light and scratch backward. 
Dropping Boards. The dropping boards 
should be laid perpendicular to the back wall, 
because if they are laid parallei to the back 
wall the operator will have difficulty in clean- 
ing them off readily. They should be 
matched boards, so as to leave no large 
crevices. 
Roosts. The roosts, in a twenty-two-foot 
house, should be in three sections, hinged at 
the back so they may be tipped up out of the 
way when the dropping boards are cleaned.
