XXVI. DISCUSSION. 
proved to him that it would be worse than useless to use fascine 
for training banks of channels again. The work at Moruya was 
an utter failure, the fascines were laid on a sand bottom, and 
when the very first flood took place the sand scoured away and 
the whole bank floated out to sea, this was anticipated by the 
then Engineer-in-Chief, Mr. Moriarty, who reported strongly 
against the use of fascine for such a purpose. The work of this 
class at Long Cove has not been the success it might have been, | 
piles had lately been driven in, and he believed that they are | 
being pressed forward. He thought that in many cases it would 
have been cheaper, and more economical to carry out the work 
with stone, for when the water in front deepens, the stone will run 
down and check the scour ; this is very noticeable at Newcastle, 
where there is a dyke of a mile and a half in length. This dyke 
was laid out by the speaker, the construction being commenced

at low water, there is now over twenty feet of water close beside 
it. The stone does not sink with the sand, but as the scour takes 
place the stone runs down off the face of the dyke and so

checks further erosion, and it is a simple matter to make good 
the loose stone again till the full depth is reached. In this 
country where in the majority of cases, our coastal harbours have

sandy bottoms, fascine work would be quite useless. In the 
case of some rivers, say the Hunter, some excellent work has been 
done with fascines, and it has been found a very effective protec- 
tion against flood, but there it is made of layers of fascine and 
stone, loaded and coated with stone. 
Mr. DEANzE, said the first cost of work was put down as being 
under three shillings per cubic yard, but he was under the impres- 
‘sion that the work costa great deal more, and he would like to 
know from Mr. ste viet where fascine work came cheaper than 
stone. 
Mr. Darley said in reply to Mr. Deane’s pene “in what way — 
fascine work came cheaper than stone”? that stone would be very _ 
costly to make large dykes of. In our river banks the introduction 
of the fascine and stones proved itself very effective, where you
