The
total cost of working has been 2.572d. per ton. which with 10 per cent
interest on capital, 0.240d., makes the total cost per ton 2.812d. The
repairs to steam tug, hopper, barges, and dredger have averaged about
2d. per ton.
Before the discussion on the paper commenced, Mr. Langley remarked that
attempts had been made to connect the engine direct to the pump of a
Bazin dredger, but this arrangement failed, and the belt acted as a
safety arrangement and prevented breakage by slipping when the pump was
choked in any way. A new lock was constructed near Lowestoft a short
time ago, and the dredger pump was used to empty it; when half empty the
men placed a net in front of the delivery pipe and caught a cartload of
fish, many of which where uninjured. In the discussion Mr. Wallick, who
had superintended the use of the dredger at Lowenstoft, gave some of his
experience there, and repeated the information and opinions given by Mr.
Langley in the paper.
Mr. Ball, London agent for M. Bazin, said that as devised by M. Bazin
the pump was placed below water level, so that the head of water outside
should be utilized; but he--Mr. Ball--now placed the pump considerably
above water level, as no specially formed craft was thus necessary.
