of different sizes, suitable for the various birds, whicn I will 

 describe later. 



Now as to feeding- and drinking arrangements : I made 

 tliree trays — one for each division — about 14 inches square, and 

 4 inches deep, putting screw eyes at each corner to which I 

 attached by wire hooks four pieces of small sized picture chain. 

 These all came to a hook in the centre which again is fastened 

 to a screw eye in the roof. Into these trays I put glass bowls 

 (old preserved meat bowls) of seed, and the birds drop the chaff 

 out of the bowls into the trays, so the fioor, etc., is kept very 

 clean. It then becomes an easy matter to tilt up the trays 

 of chaff into the bowls and riddle out the good seed tliat is left. 

 Eefill the bowls with fresh seed and replace them in their trays. 

 For soft food, etc., I use the little delph pots that one gets 

 potted shrimps in; they are so easily cleaned and kept fresh. 



For water I use enamelled steel dishes of various depths 

 to suit the birds; they are white so one can keep them spotless, 

 and thus one is sure of the birds getting fresh drinking and 

 bathing water. 



For nesting boxes, I made a number from all sorts of 

 suitable wooden boxes drilling a hole with an " Extension 

 Bit " — by the way a most useful instrument because it drills a 

 hole of a diameter of %in. up to 3 inches, and comes in useful 

 for all sorts of purposes connected with the aviary. 



The account of my birds must form another story.

Breeding of Leadbeater's Cockatoo (Cacotua lead- 

 hcatcri). One does not often hear of cockatoos breeding in 

 captivity, but at the present time in the London Zoo, at the rear 

 of the Parrot House, is to be seen a happy family of Lead- 

 beater's — the parent pair and two babies. This species is one 

 of the most, if not the most beautiful, of the large genus 

 Cacatua. Only on one occasion previously has complete success 

 been attained in breeding the species in the Gardens, when one 

 or two young birds were fully reared in the large aviary (now 

 given up to monkeys) on the banks of the canal, almost opposite 

 the Parrot House. Returning to the nresent success, both
