He has a close relative, the Letter-winged Kite, an 
inland bird, very seldom seen on the coast, whose colour- 
ing is the same as the Black-shouldered, except that the 
black extends on the under angle of the wing, forming the 
letter W when the wings are extended, hence the name.. 
I think this species catches mice or small rats. 
One of the first birds noted on the way to the 
Woogaroo Scrub was the Dusky Wood Swallow. He 
was chasing some insect, which finally fell to the ground,, 
when the bird dropped down and caught it, taking it to 
a nearby branch, beating it into a convenient shape, then 
swallowing it. The bird has a wide range, but in some 
parts of the Southern States is a migrant, arriving in 
August or September, and departing in April. Appar- 
ently they feel the cold, for in winter or rainy weather 
they go to roost in a, cluster on the underneath side of a 
leafy tree. Those that I have seen have been about 6 
feet from the ground, just like a large swarm of bees 
hanging on to each other. A. J. Campbell mentions that 
occasionally a few dead ones are found underneath where 
they have been hanging; probably they were suffocated 
or died from cold. When they have been suddenly dis- 
persed by fright, the simultaneous noise created by the 
multitude of wings has been compared to a mild clap 
of thunder. The swarms I have seen were not large 
enough to make such a noise, but quite loud enough to- 
startle his horse if riding close by.

REVIEW. 
AUSTRALIAN RAIN-FOREST TREES Excluding 
the species confined to the Tropics. By W. D. Francis,. 
Assistant Government Botanist, Brisbane, pp. XI, 347. 
Including numerous illustrations. Government Printer,

The work under review is undoubtedly one that 
should be in the hands of all those who are at 
all interested in Australian trees. To people in 
States other than Queensland and New Sout h Wales 
it reveals the wealth of tree species to be found in the 
New South Wales brushes and Queensland scrubs as the 
rain-forests are termed in their respective States. To 
the tree-lovers of these two States of the Commonwealth 
the work should be of distinct use for the purpose of 
identifying the trees of the rain-forest areas. Probably 
no one was better qualified than Mr. Francis to produce 
such a book, as interest in and intimacy with the 
Australian sub-tropical rain-forest have given him a won-
