with the port believe that the
changes from year to year will be
very slight. The work thus far &C
complished shows that the entire
length and breadth of the bar may
readily be removed at a compare
lively small expense, the Govern
ment possessing the dredge and all
the necessary equipments. At the
same time the sand excavated may
be utilized in making new land
bordering on the entrance, the
value of which would in part re-
coup it for the outlay.
In addition to what has already
been accomplished in improving
our harbor, Superintendent McIn-
tosh informs US that he intends
Immediately to dredge the harbor
alongside the Pacific Mail wharf to
depth of so feet or more, so that
in case large steamers requiring
that depth to enter port, can lie
alongside this wharf and discharge
or receive freight without the delay
of Tightening heretofore required.
Another improvement that the
Superintendent will urge, is the
construction of a new dock at the
east end of the Pacific Mail wharf,
running inland 400 feet by $50
feet width, which will enable two
of the largest size ocean steamers
to lie in the dock at the same time.
Experiments have shown that 80
feet depth can be obtained there
by the hydraulic dredger, the bot
tom consisting only of mud, black
sand or coral, throughout the en-
tire space needed for this large
dock.
1t will thus be seen that the har-
Dor of Honolulu has undergone an
entire change, and for the future
must take rank among the best
for the largest vessels afoat.
While it is and must remain a
small harbor, it's accommodations
for very large steamers will be
such that they can always enter
port day or night, and steam up to
dock or wharf without changing
their course, and in leaving port
can, by means of a hawser, swing
around in the ships length, and
steam out to sea on bee line from
the dock. In short, Honolulu will
soon become a favorite and safe
calling place for merchant or war
ships drawing not over thirty feet
of water, whether stopping for a
few hours only to land passengers,
or to secure freight or supplies of
coal.
Two diagrams have been pre-
pared to give some idea of the
nature Of the work that has been
accomplished.
FIG. [. represents the bar in the
entrance to the harbor. 1t is sim
ply bank of coral sand that has
accumulated there, and was prob
ably thrown up by the sea during
heavy storms. The harbor is
located at the left, the ocean at the
right. The bar extends between
100 and 1900 feet in length, and
the dredging has been done for
this distance, as is shown by the
light shaded bank, now removed.
The depth of water on the bar,
indicated by the dotted line along
the bar, is not less than thirty feet
in any place, while in a few spots
the lead shows thirty-six feet, indi-
eating that this depth might be
obtained throughout, if desired.
FIG. II. is a cross section view
of the channel, showing the exca-
walton made at the deepest cut on
the bar, with the old bottom re-
naming on each side of the new
channel. The hull represented in
the center shows how vessel
drawing say twenty feet will have
ten feet of water under her keel in
any part of the new channel. This
channel is 200 feet wide at the
bottom, and 1900 in length.
