AVIARIES, BIRD-ROOMS AND CAGES. 



other joint, if neatly done, is quite strong enough and 

 looks very well. 



When marking the wood for these joints, it is 

 necessary to use a square, as we shall by this means be 

 able to get our work true and consequently to fit well. 

 Having made these we just put them together to see 

 that no mistake has crept in, but do not yet nail or screw 

 them. 



We have now to mortice the top and bottom bars 

 to fit in the uprights E and F. Fig. 5 shows the hole 

 made, which is accomplished with mallet and chisel. 

 It need not be cut right through the bar; if it just fits 

 in say one inch, to hold it secure, this will be quite 

 sufficient. From our plan, Fig. i, we can see the exact 

 distance these will be apart. To prevent mistakes make 

 the holes in one bar first, then lay the other beside it, 

 and mark the places with the square and pencil. Before 

 putting the frame together, we have to mortice F and 

 D to receive the cross-bar G, also to cut the ends of C, 

 E. F, D, as shown in Fig. 6.
