lowed, and show thorough knoWl-
edge of the work submitted to him.
In 1891 Messrs. Bruner, of the
Bureau of Public Improvements,
and Dodge, of the Government
Survey Service, made a very ex-
haustive survey of the bar, in
which sixteen hundred soundings
were taken, which is probably as
thorough service of this kind as has
been done under any government,
and will enable future administra-
tons to ascertain just what changes
time and heavy storms make with
the bar and the new channel. From
this survey the route of the new
channel, 200 feet wide, 1850 feet
long, and 80 feet deep, has been To-
Gated.
The Legislature of 1890 having
voted 100000 for deepening the
bar and for harbor improvements,
a contract was Immediately en-
tered into with the Risdon Iron
Works of San Francisco, through
their agent here, Mr.. Jno. Dyer, to
construct hydraulic dredger with
hull 40x100 feet in size and nine
feet deep, fitted with main cen:
trifugal pump with a runner four
and half feet in diameter, and
driven by a pair of compound con-
densing engines of $50 horse pow
er, one pair of engines for cutter
gear of Is horse power, and pair
of engines for operating the wind
ing gear, handling the dredger, ETC.,
also of rs horse power. In con-
nection with the dredger there were
1000 feet of floating pipe and 5000
feet of shore pipe. The capacity
of this plant was required to be
10000 cubic yards in smooth water
per month, or 10000 cubic yards
of coral sand on the bar per month.
After numerous delays caused
by southerly winds and heavy
swells on the bar and in the chan
mel, the dredger got fairly at work
about June 18th, and worked very
satisfactorily, discharging the sand
through the floating pipes into the
enclosed dumping ground on the
reef, an average distance of over
$500 feet. The result has been
that the Government has now an
area of % acres reclaimed from the
sea, which will in time become a
valuable addition to it's available
water front.
The entire cost of this great i'm
provement to the harbor has been
about $4,000, of which $65, 900
was expended for the dredger, and
the balance for work connected
with deepening the bar. The guam
tity Of sand removed amounts to
$1,000 cubic yards, thus exceeding
the estimates made by experts
some few thousands, but still a
close approximation. No mishap
of any kind has occurred during
the progress of the work, and both
the contractors and the Govern
ment are to be congratulated on
the results obtained.
The completion of this work,
which has been looked forward to
with great interest, marks an era
in the facilities which Honolulu
Harbor offers to the increasing
Trans-Pacific trade, as there no
longer exists any obstacle to pre-
vent the entry Of the largest war OF
merchant vessel afoat in this
ocean. Of the numerous steamers
plying between New York and Eu-
ropean ports only three draw &c
