netting. This should be painted green or gray before the netting is 

 applied. Regular aviary netting of 1 by J inch mesh, or poultry 

 netting of j-inch mesh, may be used. The door has a hook on each 

 side and spring hinges. Around the top of the cage extends a shelf 

 (fig. 10-c) about 8 inches wide. 



The underside of the frame (fig. W-d) is perfectly flat all the way 

 around, in order that the partitions may be attached at a uniform 

 height. The ends of two opposite sides extend 6 inches beyond the 

 square to allow the supporting blocks to be placed where they will 

 not hinder the entrance of sparrows when the corners are" open

(fig. 10-/). The outside measurement of the frame is an inch larger 

 all the way around than the inside measurements of the shelf. After 

 the frame has been painted and covered with wire on the uneven 

 side, it is placed in its final position with relation to the shelf, but 

 without the supporting blocks, and is marked by a pencil drawn 

 along the inner edge of the shelf to show the position for the outer 

 edges of the partitions. 



The partitions are sheets of tin 5 inches wide and 6 inches long, 

 having a flap turned over at the top for attachment to the frame and 

 another flap on the outer edge for attachment to the shelf (fig. 10-5).
