SAND-DRIFT PROBLEM IN NEW SOUTH WALES. 105 
systematically set to work. Iam perfectly certain that if 
anything can be done in this direction good gardeners can 
do it, and preliminary work can afterwards be extended to 
any desired extent. 
There is no necessity to supply a long list of plants for 
experimental cultivation, either native or exotic. I will 
content myself with very few. »If I were permitted to 
carry out my plans, I would attach the gardeners-in-charge 
of the proposed depots to the Botanic Gardens for a brief 
period, in order that they might critically examine all 
plants likely to be useful for their purposes which are grow- 
ing in the Garden, and for exchange of ideas which must 
be beneficial to all good men. Then I would have experi- 
mental plantations made on the coastal sand-dunes near 
Sydney and study the lessons thus taught. 
8. Plants recommended for Western sand-dunes.—Just 
as the Maritime Pine is the principal planted tree of the 
French Landes and just as Irecommend the Norfolk Island 
Pine for our coastal sand-dunes, so I recommend the 
Cypress Pine (Callitris) as the main stand by for the shift- 
ing sands of the West. It isa tree of commercial value, 
and parenthetically I may enjoin discretion in cutting away 
away existing Pine forests out west. My policy would be 
to raise rows, and cross rows of Cypress Pine in sandy 
country inside the Barrier Range; it is natural there, and 
Sturt’ floundered over successive ridges of deep loose sand 
and became entangled in a Pine Forest near the Barrier 
Range. 
Sugar Gum (Eucalyptus corynocalyx). E. fasciculosa, 
F.v.M., and other Western eucalypts, (especially Mallees) 
should be encouraged. 
Various Acacias such as Mulga (A. aneura), Yarran (A. 
homalophylla), Myall (A. pendula), A. cibaria, A. sentis,
