enclosure except this — that it should be sufficiently wide for a 

 bird, when standing in the middle, to feel itself in a position of 

 safety from visitors wiio may be passing at the same time along 

 both sides of it. In the enclosure will stand the hut into which 

 bustards or cranes or flamingoes can be walked on occasion, 

 trees on which pheasants can climb and sit, and any shelter that 

 may be required for other birds. Such are a few points about 

 enclosures. 



The Aviarv. Aviaries may be made — of course they are 

 made — in various ornamental manners. For certain tropical 

 birds they need heating, or half-heating ; for certain other tropi- 

 cal birds they need artificial light on winter days. The writer 

 having had no personal experience of these, and conceiving an 

 "ornamental " aviary to be an abomination, will merely describe 

 here the pattern of aviary used by himself for hardy birds, and 

 one that absolutely simple in design and construction, seems to 

 him to be practical and sufficient. 



The outside enclosure measures i2 feet long by 8 feet wide 

 and 7 feet high ; inner house 8 feet b\' 6 feet. The framing of 

 tlie outer part is of creosoted deal 3in. by 2in. The wire-netting 

 covering is 6ft. wide and is of f-inch mesh. (1/ the ver}' smallest 

 birds are to be kept it should be i-inch). A double width ot 

 netting then exactlj' covers the top and sides : a single width the 

 front leaving a space of i2in. below it. (It will be obvious that 

 the view through the front will therefore be clearer than that 

 through the sides, since the netting will run in the opposite way, 

 and for normal eyes horizontal lines are better than vertical). 

 The space between the bottom of the netting and the ground is 

 made out with boarding. It is best to have this i8 inches deep
