ones. The African Silverbills also nested, but all their eggs 
were infertile. 
Aviary No. 4 (.^0 foet x 15 feet x 15 feet): Here 
results were a little better, but below expectations. The 
aviary contained: Cockateels (two pairs); Ring-necked, Mous- 
tache, and Pennant Parrakeets; Peaceful, Aurita, Zebra, and 
and White-winged Doves; Java Sparrows; Saffron and Zebra 
Finches, and Californian Quails. The Quail successfully reared 
eleven young (over fifty eggs were laid). The Cockateels 
nested several times, but, only raised to maturity five young 
ones. The Zebra Finches fully reared four young ones, none 
of the others attempted to nest. 
Aviary No. 5 (40 feet x 30 feet x 8 feet): Here I 
had quite a numerous series: Crested Doves; White-cheeked 
Crested, and Argoondah Quails; Green Cardinals; Pintail and 
Paradise Whydahs; Napoleon, Grenadier, Orange and Red- 
billed Weavers; Orange-cheeked, Golden -breasted, and St. 
Helena Waxbills; Cordon Bleus; Military, Yellow-wingied, 
Orange -shouldered, and Brown -headed Troupials, Silky Cow- 
birds, and a Pagoda Starling. 
As this aviary has plenty of natural cover I had great 
hopes of success with some of the birds, but, though attempts 
were fairly numerous, results turned out to be nil. 
The White-cheeked Crested Quail laid fourteen eggs 
in a thick clump of grass, and after incubating very steadily 
for thirty days brought off twelve chicks, none of which lived 
ovei" a week, the old birds proving very bad parents. 
The Argoondah Quail delayed operations till Novem- 
ber, when seven eggs ^^ere laid, but these were all punctured, 
probably the cock was the culprit. 
The Crested Doves proved to be two cocks! 
The Orange-shouldered Troupials were, I think, two 
hens. They built two nests, the first in a Black Spruce, and 
the other in a Box bush, both nests being very similar to 
a Blackbird's. They laid five eggs, pinky-white, closely speckled 
with fine red spots in the second nest, but jnade no attempt 
to incubate. A week later, five more eggs were deposited 
in the first nest, these were creamy white, with large brown 
patches at the larger end, and much elongated in shape. Both 
incubated these eggs very carefully but, all were infertile, and
