On one grass-tree, about four feet in height, Asplenium 
falcatum, Dendrobium speciosum, Cyclophorus serpens , 
and Polypodium pustulatum are associated. Another 
had the climber, Fieldia australis, rooting on its trunk. 
The trees surrounding the Xanthorrhoeas and Eucalyp- 
tus are about twenty feet in height, and are all young, 
vigorous trees. Beyond the edge of the thicket, the van- 
guard of the advancing forest is represented by seedling 
beeches in all stages up to about six feet in height. They 
were scattered through the open forest for a distance of 
some twenty yards down the northern slope, and are 
strong, vigorous young plants. There seems no reason 
why they should not grow to maturity, provided bush 
fires do not sweep the area before they form a closed com- 
munity. It will be interesting to see how long it is be- 
fore the Xanthorrhoeas and Eucalyptus are finally sup- 
pressed in the area that has already been effectively 
colonized.

LAMINGTON NATIONAL PARK. 
BIRDS. 
By Geo. H Barker , R.A.O.A. 
The weather during the outing was fine, and, al- 
though cold at night, was quite warm, by day. A number 
of birds were seen, though very few were counted in any 
numbers, at least as far as my own observations were con- 
cerned. One exception must, however, be mentioned, and 
that was the Sulphur-crested White Cockatoo, of which 
as many as fifty were seen at one time. Morning and 
evening this noisy, screeching nuisance would be seen and 
heard, sometimes on the hill side, sometimes in wheeling 
flocks, often after sundown, before settling down for the 
night. Magpies and Magpie-Larks and Crimson Roscllas 
were also much in evidence at all times, and with a small 
dock of Dusky Wood Swallows were about the only other 
birds seen in companies. 
Of the fifty-eight species appearing on my list for 
the holiday, most of them were the ordinary species one 
v ouM see on any general excursion on a Saturday after- 
noon in the Brisbane district. 
Among the unusual specimens might be mentioned 
the Fruit Pigeons, of which we saw two species, The
