DREDGING FOR CHANNEL.
After the work in Divisions l, III, III shall have
been done, il may become necessary to dredge the
space between the extension Of the south and the
prolong CATION of the line of north pier to obtain
depth of channel Of ii to Is feet below the low stage
This will be estimated In cubic yards, and the
price for dredging and dumping the same cut OF
the way in deep water to be bid for. Our surveys
now show about II 900 cubic yards of this deposit
requiring removal. .... =.
DIVISION v.
BREAKWAIER TO IMPROVE THE EXISTING HARB0P
AND TO AFFORD REFUGE.
This II designed to be 900 feet long, to stand in
straight line which the average depth of water
below low stage is feet to consist of cribs 50 feet
long placed end to end. made Of square timbers.
The sides of the cribs to rise from the bottem with
batter Of 81 -lo0ths, 30 the cribs shall be Is feet
wide at the low water surface and thence the faces
OF the to rise vertically feet above
said surface TIE widths of the cribs at bottom
will be from 3la to 80 feet, according 10 the depths
which they stand, the whole work to be filled
with rubble stones mp to bottom of top tmbers and
planked over. :,
The cribs, eighty in number. will require for their
construction
