what he was doing, Corella flew down again and so secured 
the egg. As one may have remarked, the Corella, with its 
long curved beek and partially bare face, presents a facial 
expression that would bespeak craftiness, even were it 
not displayed — as so often happened — in the case of this 
erstwhile pet.

THE PINES OF AUSTRALIA.* 
The Technological Museum of New South Wales has 
prepared, and the Department of Public Instruction of 
that State has issued, a work (now before the members) of 
singular interest and importance, the outcome of an ex- 
haustive investigation pertaining to our Australian Coni- 
ferse, in which Messrs. R. T. Baker and H. G- Smith ■ 
Avho have already earned fame through their joint Re- 
search on the Eucalypts ” — have, whilst keeping sight 
of the commercial value of the important asset that these 
trees constitute, regarded them from both a chemical and 
botanical standpoint, using these terms in their fullest 
significance. Obviously, the most predominant genus of 
the group alluded to, Le., Callitris (Cypress Pine), with its 
18 species, claims the fullest treatment in it, but ample 
consideration also is bestowed on the trees included in 
Araucaria (Hoop Pine, White Pine, Bunya Pine), Podo- 
car}nis, Agathis (Kauri), Phyllocladus, and other genera 
indigenous to the territories of the Commonwealth. The 
Cypress Pines — exclusively Australian trees — moreover re- 
ceive at the hands of the authors prior consideration : a 
general account of them, under no less than 21 diiferent 
headings, being followed by the separate treatment of each 
individual kind, due attention being given to (1) history 
of the species ; (2) its systematic relations ; (3) the leaves ; 
(4) the wood ; and (5) the bark ; in each case separate 
divisions being allotted to the economics, anatomy and 
chemistry of these. And this mode of treatment is pur- 
sued also Avith respect to the trees of other coniferous 
genera. 
The comprehensiveness of the monograph before us 
may be concluded from the fact that it embraces more than 
450 pages 4to. of letterpress, a large number of plates, and 
no less than 298 figures. These illustrations, in addition 
to portraying the characteristic features of the trees them- 
selves, largely deal with the microscopical structure of their 
leading tissues — comprised severally in Avood, bark, leaf,
