Lighthouse.—No better site can be
found than the summit of the hill form-
ing the Lighthouse reserve, which is an
excellent position.

A fixed Catadoptric light of the
first order, with Light Tower and Lan-
tern 40 feet high, erected complete,
will cost £4900 0 0
Annual cost of maintenance 580 0 0

A similar light of the second order
with Tower of the same height will
cost £3600 0 0
Annual cost of maintenance 460 0 0

A similar light of the third order with
similar Tower will cost £2800 0 0
and annual expenditure be 340 0 0

The cost of Lightkeepers' dwellings
and salaries will be the same whatever
class of light is used, so that the only
saving effected by a light of the third
order over one of the first order, is in
the consumption of oil.

As there are no outlying dangers at
a great distance from the site of the
Lighthouse, and as vessels, from what-
ever direction they may come, will al-
ways sight the land before entering
Hawke's Bay, it is unnecessary to pro-
vide a light of the first order.

It is therefore recommended to pro-
vide one of the second order, which
possesses nearly 3 times the power of
a light of the third order, at the same
time that the increase in the first cost
and maintenance is comparatively in-
significant.

Hoping that the above report will
prove sufficiently comprehensive,

I remain,
Your Honor's most obdt., servt.,
EDWARD G. WRIGHT.

To his Honor the Super-
intendent &c., Napier.

Napier, August 12, 1859.

SIR,—Reverting to your letter of the
1st inst., in which you request me to
report upon the best means of providing
efficient house-drainage for the low,
level districts of the Township, also
upon the best method of supplying the
Town with water, and the most suita-
ble site for a Reservoir,—I have now
the honor to report as under; first ob-
serving, that as an abundant supply of
water is not only necessary for the con-
venience, health, and cleanliness of the
inhabitants, but that water will also be
required for flushing out the drains in
the low districts, it is perhaps better to
consider the water supply first.

The most convenient source from
which to obtain a good supply of water
for the Town and Port of Napier, is
the Tutackuri river, a little above the
spot whence it is now taken in barrels
for the supply of the residents on the
Eastern Spit. Here it would be ne-
cessary to excavate two settling reser-
voirs, for getting rid of the grosser im-
purities held in suspension by the river
water, and the earth excavated would
form an embankment round the reser-
voirs, and protect them from the influx
of muddy water at the time of floods.

The water would be admitted to the
reservoirs, by conduit pipes from the
banks of the river, or should the
ground be not sufficiently porous on
excavating to the required depth, the
conduit pipes might be dispensed with
and the water allowed to percolate from
the river to the reservoirs, the river's
bank thus serving as a natural filter.

Adjacent to the reservoirs, a house
must be erected to contain a Steam
Engine, Boiler, and Pumps of sufficient
power to raise the daily supply of wa-
ter into the service reservoir, the best
position for which will be on the Edu-
cation Reserve at the top of the Shakes-
peare Road, (about 160 feet above the
pumping station,) whence the water
would be distributed by the service
mains, throughout the Town and Port.

On first consideration it may appear
an extravagant expenditure of power
to raise to this height of 160 feet the
whole of the water for supplying the
low level districts, about Carlyle and
Hastings Streets; but either the
whole of the water must be so raised
for the sake of getting it over the hill
to the Port, or the Port must be depriv-
ed altogether of the benefit of the water
works, or recourse must be had to two
service reservoirs, one at the above
named level to supply the Port, and
one at a lower level to supply the Town;
and this latter arrangement would be
the best, provided the population in-
creased but slowly as in old settled
countries, and indeed will be the plan
to be adopted here, whenever the po-
pulation shall increase to 6000 or 7000
souls. In the meantime, as it will
