AVIARIES, BIHD-TtOOMS AND CAGES. 25 



washed ready for the show bench. He was singing the 

 whole of the day; but on the third day afterwards he was 

 dead. Healthy and well, he took no notice of the 

 exposure, but going to roost with a wet jacket was 

 evidently too much for him. In a very large flight 

 partly unroofed, there would hardly be so much danger, 

 as the extra flying space would keep the blood well 

 circulated, so to speak and, of course, a goodly portion 

 would be covered in. 



Fig. 19. A Simple Form of Aviary. 



Fig. 19 shows a very simple aviary. An examina- 

 tion of the diagram will give one an idea of the ease 

 with which it can be made. The sides and roof are all 

 in one piece, so that we do away with a good deal of 

 timber and labour in constructing it. It is only partly 

 covered in, and has a door in the covered end. There 

 is no difficulty in entering it, as the birds are mostly at 

 the opposite end where the light is. One in use is 

 placed in a meadow, where the trees shelter it, and is 

 occasionally shifted to fresh ground, the latter being 

 generally done in the evening, just as the birds are 

 roosting. "Such a building is more suitable to the larger 

 bircks. The one actually in use, when last I saw it, con- 

 tained various Doves. The objection to this aviary 

 is the limited flying area, the greater part of the space 

 being near the ground. 



ELABORATE AVIARIES. 



At times some very elaborate aviaries have been 

 constructed for special purposes, but of course the con- 

 ditions have been in every way favourable, the space 

 unlimited, and the expense not a great consideration. 

 A stream running through private grounds has been 

 wired over, including the bushes and rank herbage
