- DISCUSSION ON MR. MAULT’S PAPER. 193 
Mr. Mavtt, in reply, said he proposed to burn the screenings, but 
that question was very much smaller than supposed. The daily volume 
of screenings of the sewage from 3,000,000 of people he had stood by 
and seen to be small enough to place on the table before him. And he 
hoped they would be burned in a destructor, which he did not think 
would be a costly affair. If anything were making the Corporation 
hold its hand it was the possibility of an arrangement being come to 
for a joint use of a destructor by the Metropolitan Drainage Board and 
the Corporation. Undoubtedly, whatever insoluble matter was brought 
down into the river muss sink to the bottom sooner or later. But he had 
shown that if the volume of insoluble matter discharged were three 
times what it would be it would take 100 years to form a deposit lin. 
thick over the bottom of Sullivan’s Cove. It would cost £100,000 to 
take a sewer into mid-stream. The sewage would be discharged into 
deep water, and there would be no danger of a mud bank forming. 
There would be no difficulty, as anticipated by Mr. Milles, in the 
definition of public and private sewers. Nor did he anticipate, unless 
circumstances were very different to what they were in towns of a 
simiJar size in England, that the cost of connection would be anything 
like £10 a house. He thanked the meeting for the patient hearing 
accorded him, 
Sir LAMBERT Dogson, in moving a vote of thanks to Mr. Mault, said 
one little matter should not be overlooked. ‘When the pan system was 
started no provision was made for emptying the pans. Before a drainage 
system was adopted there must be a water supply, otherwise the diffi- 
culty would be repeated. Therefore the public would be in the hands 
of the Corporation, and could not have proper drainage till a better 
water supply was provided. He quoted the opinion of a gentleinan 
holding a high sanitary degree in England to the effect that the greatest 
danger to health wes from the slops from houses. 
The vote of thanks was unanimously passed to Mr. Mault, who 
acknowledged it.
