582 FOREST CULTURE AND 
frozen. At Golf Juan the tree does not suffer. It 
comes within our observations in a scientific garden 
why wood is more durable when produced on certain. 
spots, as compared to that of other localities, and in 
a similar manner should be carried on undisturbed 
utilitarian research in manifold other directions. One 
single plant of a tree, once obtained, can become the 
progenitor of vast plantations. It is no exaggeration 
when I say, that from a single imported Asiatic Ash 
15,000 young trees were obtained by me for Victoria, 
and that from a solitary Tamarix-plant 20,000 bushes, 
now scattered through our colonial shrubberies, took 
their origin. 
It should be ascertained how many of the 160 true 
species of Willows and of their numerous hybrids 
are available for wickerwork ; and we should learn 
whether any of the American, the Himalayan, or the 
Japan Osiers are in some respect superior to those in 
general use. Weare aware that the Sal (Shorea ro- 
busta) is hardier than the Asian Teak (Tectonia grand- 
is), the latter naturally not thriving beyond the tropic 
circle ; but we are not aware whether the Sal will 
live in any sheltered forest clearings of Victoria, and 
how far the Sisso (Dalbergia Sisso), which is hardier 
still, and which, according to Colonel A. Crawford, 
stretches to the thirty-second degree, north, in the 
Punjaub, can be adopted as a forest tree for this colo- 
ny. Insolving such questions, a scientific garden may 
afford material aid. We should like to see how far. 
Californian Red wood-trees (Sequoia gigantea), or New 
Zealand Totaras, may give us good timber, when 
merely grown from cuttings in the open air.
