The loor has an opening 18x24 inches, covered outside with 

 J/2-inch mesh galvanized wire netting and fitted on the inside 

 with a frame covered with light muslin. This frame is hinged 

 at the bottom, permitting it to be swung downward on the in- 

 side during the mild weather or to admit sunlight. 



Figure 1 shows the general outside appearance of the build- 

 ing after construction. 



NESTS. 



There are 5 nests altogether, placed on the left side of the 

 building although it would be possible to place nests on the 

 opposite side if desired. The nests are removable for cleaning 

 and rest on brackets nailed to the studding. The partitions, 

 bottom, and front of the nests are nailed together. The plat- 

 form in the front of the nests is 4 inches wide and is set out 

 2 inches in front of the nests in order to prevent the latter 

 from becoming fouled with droppings. Seven-eights inch ma- 

 terial is used throughout in the construction of the nests. 



ROOSTS AND DROPPING BOARD. 



The dropping board is made to slide into place at the rear 

 of the building over strips nailed to the plates at either side.
