Avenue Trees. 
Trees for an avenue, or for a well denned part of it, should be of the same 
kind. Every celebrated avenue in the world, e.g., the Horse chestnut avenue of 
Bushey Park, near London, and the Cryptomeria Avenue of Nikko, Jipan, are of one 
kind of tree. The mixed avenue is an abomination, ragged and irregular at the best. 
If the continuity of an avenue has to be broken, let it be at some well-defined break, 
such as the junction of an intersecting road, or where the road debouches on to a .squaro. 
If you take an expanse of any length in street planting it is difficult to secure 
uniform conditions above or below ; that is one of the reasons why it is so hard to obtain 
precision in an avenue, which is one of its merits. 
A level plain, with soil, drainage and other conditions uniform, is an ideal as 
high as we can get, but even then, in say a hundred planted trees some will be found 
to greatly exceed in vigour or be greatly inferior to the average, and, if this be observed 
only when the trees are fairly large, it is not easy to rectify matters. 
Avenue planting requires careful judgment of a high order. 
Roadside Trees in Country. 
Much of what has been said is more appropriate, perhaps, to towns of greater 
or larger size. But the requirements of the resident of the country districts must not 
be lost sight of. Many a man has lost stock through driving them along a shadeless 
road, and more still have seen their animals much distressed for the same cause. 
Often shadeless roads are caused through the cupidity of the adjacent landowner 
who begrudges the tree outside his fence the nutriment it gets from his land. The 
remedy is not to plant his crops so near the edge of the road. In most cases the land- 
owner can be fairly expected to possess sufficient civic spirit to make some sacrifice 
to enable the trees along the side of the road (probably not planted by the hand of 
man) continue to render public service. And he should always bear in mind that 
he himself probably gets more advantage than anybody else from the presence of the 
trees. 
List of Trees. 
It is very difficult to make a condensed list of trees suitable for New South Wales. 
Our State is a very large one, with many soils and climates, and I have, in another place, 
divided it into five portions. (1) The cold region, consisting of the north and south 
tablelands here British trees flourish; (2) the coastal strip; (3) the Northern Rivers, 
a distinctly sub-tropical belt, forming the north-eastern portion of the State; (4) the 
\Ycstern Slopes and Riverina ; (5) the Western Plains. 
If I were to attempt an even simpler classification as regards trees, I would 
suy (a) Cool districts with (1) dry, or (2) damp localities; and (b) warm districts, with 
(1) dry, or (2) dtmp localities. Damp localities are often associated with shelter. 
Trees which grow in dry situations often do better in moister situations with improved 
soil. Then again we have light soils, stiff soils, limestone soils, and so on. It is obvious 
that I can ouly lightly touch upon our varied conditions and requirements on the 
present occasion.
