third part on the south b}^ a movable wooden parti- 

 tion. Within this second chamber, against its east 

 wall, is a sort of inner aviary six feet b}^ two feet 

 superficial, which is also constructed of wire and 

 glazed shutters ; it has a window in the east wall four 

 feet by three feet made to open outwards and protected 

 by wire netting ; this inner chamber is intended for 

 small Finches. The roof of the sleeping chamber and 

 covered flight is constructed of match-board, felt 

 " rubroid," and corrugated iron, and provided with 

 guttering and R.W. pipes communicating with brick 

 wells to carr}^ off the rain water ; the roof has a pitch 

 of three feet and the ridge is protected by a saddle 

 and decorated by a scroll ; there is also a scroll 

 border along the eaves. In continuation of the 

 covered flight is the third part or open flight — 

 this space like the sleeping place is six feet square ; 

 two sides and the roof of this space are of open

 separated from the middle or covered flight by 

 two folding doors, which can be shut up at night 

 or removed altogether in the hot summer months ; in 

 this way the aviary can be made one continuous 

 space. The concrete floor in this part of the aviary is 

 hollowed out into a basin, which forms a bath for the 

 birds to wash in— this bath is provided with a standing 

 waste, which keeps the water always at the same level. 

 Beyond the open flight is a vestibule of approach, 

 entirely constructed of wire netting and having two 

 doors — one opening into the aviary the other into the 

 garden. 



The furniture of the aviary consists of hard oak 

 transoms suspended from the roof by stout wire and 

 forming trapezes ; in the open flight there is a rotatory 

 system of perches turning on an axis, which extends 

 from floor to roof; all along the spring of the roof are
