The value of Paspdum dilatatum and Rhodes Grass (Chloris Gayana) 
for sand-binding purposes has not been thoroughly tested in New South Wales yet. 
Paspdum proved useful on the Macleay River in a case in which I recommended a 
farmer to try it. A large area of good land had been completely covered with a thick 
layer of sand brought down by a flood.

Reference may be made to the admirable paper " Sand-binding Grasses," by F. 
Lamson-Scribner, in the Year-book Department of Agriculture, U.S.A., 1898, p. 405, 
which has illustrations of Marram Grass planting in the United States (Cape Cod, Mass.). 
Also a number of additional grasses are recommended for trial, and for these the paper 
itself should be perused. It also deals with the problem of forming the dune Uttorale.

In dealing with the coastal drifting sands, the relation of cause and effect is very 
obvious ; in deajing with the interior sands, their dire effects are very obvious, although 
their causes and source are less clear. It is with the view of drawing attention to 
the paucity of information in regard to the causes of our Western Sand-drifts and of 
endeavouring to outline a method of dealing with them on scientific principles that the 
present paper is submitted.
