fencing off above high-water mark. A substantial fence 
should be erected, barbed wire being freely used in its con- 
struction, the wire so close that not even the smallest dog 
could get in. Trespass within the enclosure should be 
severely punished. I have emphasised the question of 
absolutely excluding the public, for this is the beginning 
of everything, and no more laxity should be shown than is 
in the case of up-keep of the dykes of Holland. The works 
at Bondi recently undertaken by the Public Works Depart- 
ment are not respected as they should be by a few selfish 
people. They break through the fences and trample within 
the enclosures to make short cuts and this can only be 
stopped by severe measures. 
5. Plants recommended for coastal sand-dunes.—And 
here I would again assert an axiom in soil-reclaiming experi- 
ments. Use the local indigenous plants to the fullest 
extent. They have arrived at their present development 
through a long course of environment. They have the 
additional advantage that in many cases they are on the 
spot.
