Dark Yellow Wood (Elms Ehodanthemia), Tulip Wood 
(Harpulla Pen dula).-— These trees grow in scrubs on the 
alluvial banks of rivers. They are esteemed for cabinet work. 
Silky Oak (Grevillia Eobusta). — Native name : Tuggan 
Tuggan. This is a quick growing tree, found in scrubs on same 
formations as Moreton Bay pine. The timber is used for 
coopers’ work, for cabinet work, and shingles for houses. 
Beech (Gmelina Lei chhardtii).-- Native name: Cullouen. 
This valuable timber grows in a variety of scrub soils. The 
largest I have seen grew on Buderum Mountain, at Mooloolah, 
on basalt, along with cedar. Again on sandy ground, near 
Double Island Point, along with pine. Also on Brisbane slates. 
This timber is found in scrubs in New South Wales. I have 
seen several trees over 5 feet diameter at 6 feet from the 
ground, and a trunk or boll of 50 feet long. There is a large 
demand for this timber for flooring boards and deck planks ; 
also, a limited demand for many other purposes. It is easily cut 
or carved, and polishes fairly. The white ants do not readily 
attack it. This is the next highest priced timber to cedar, and 
ought to be cultivated. Mr. Hill informs me it is difficult to 
propagate. The seeds are ripe in January. After a tree has 
had a crop of seeds, several years elapse before it has another. 
Eeference might be made to many other scrub trees, but as 
I can give little or no information concerning their peculiarities, 
or uses, they are beyond the scope of this paper. Before 
dismissing the matter of scrub trees and bushes, I may add that 
they might be used as belts of shelter trees, and also as a stop 
to bush fires. Both of these, I presume, are much required on 
the Darling Downs and other places. The ground would have 
to be fenced oft, the seeds sown, or trees and bushes planted, 
and the grass kept down for a few years till the trees and bushes 
covered the ground. Be it observed that this is a matter of 
pure speculation on my part. I do not know that scrub bushes 
and trees would grow under such circumstances ; yet I fail to 
see why they should not do so. Once they covered the ground 
and prevented grass growing under them, there would be no 
danger of bush fires passing through. Gum trees and other 
forest trees would have to be kept from growing too near to 
them. Why forest trees grow in one place and scrub trees in 
another is a subject deserving consideration ; yet no reason 
which I have learned will hold good in every instance. Eough, 
steep, broken ground, into which the roots of trees can penetrate 
a considerable distance, is often covered with scrub. Basaltic 
hills are nearly universally covered with scrub near the coast. 
On Darling Downs this country has the best grass, and is forest. 
In the Brisbane slate and sandstone country the ridges are 
covered with forest timber, but in some of the valleys or along 
the watercourses there are scrubs. At the same time 1 know of 
places where the scrub goes right over the tops of the sandy
