surface with their hoofs. Horses run along the shore for exercise and their owners 
sometimes put them on the slopes, with a result most disastrous to the reclamation. 
People have free access to these sandy slopes facing the ocean; they break them down, 
and with cattle, horses, dogs, and human beings, it is a wonder to me that there is any 
growth on these places at all. There is but one remedy, and that is the rigorous fencing 
off above high-water mark. A substantial fence should be erected, barbed wire being 
freely used in its construction, 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 upkeep of the dykes of Holland.. 
The works at Bondi, when first undertaken by the Public Works Department, were not 
respected as they should be by a few selfish people. They broke through the fences and 
trampled within the enclosures to make short cuts, and delayed the work very much. 
5. Plants recommended for coastal sand-dunes. 
And here I would again assert an axiom in soil-reclaiming experiments. Use the 
local indigenous plants to the fullest extent. They have arrived at their present develop- 
ment through a long course of environment. They have the additional advantage that 
in many cases they are on the spot.
