AVIARIES, BIRD-ROOMS AND CAGES. 15 



Possibly one might think the cross-bar G quite un- 

 necessary, but this is put there to prevent the escape of 

 birds when the door is opened. In dashing about when 

 frightened, birds invariably fly to the top of the wire 

 netting, and by having a strip directly over the doorway 

 many will be saved which otherwise might easily get 

 out. 



We can now fix our frame together, putting two 

 screws into each corner. Screws should be used in 

 preference to nails, as they hold tighter, and are able 

 to draw the wood closer together, so making a much 

 better joint. Before screwing up, just put the square 

 into each corner and see that the framework lies fairly 

 true. That of the door should be made in much the 

 same manner, and should have a cross-bar for extra 

 strength (Fig. 7). 



We must now proceed to make the frame for the 

 side as shown in Fig. 8. Be careful when doing this 

 to get the bottom bar quite square with the upright, or 

 else the aviary will not be true when fitted in position.

But before doing so we will board the bottom as
