ENGINEERING.
EXEMPLIFIED BY THE WORK AT
McBRYDE.
A Water Supply and Distribution Sys-
tenn as Extension as for a Large
City-Railroads and Bridges.

The report of e. e. Conant, manager
of the McBryde Sugar Company for the
year ending December 81, 1899 has just
been issued For others than stock
holders there is much of interest in It,
showing as it does in a very clear way
immense engineering work the creation
of a large sugar plantation involves.
LAS far as water is concerned" says
the report. THE company is out Of the
woods"
The water supply is from two sources,
wells and water courses. The wells are
five in Hanapepe valley, which flow
about nine feet above sea level, the
water being of good quality averaging
only about twelve grains of salt to a
gallon. There are four good wells in La
wal and two others nearly completed.
AS at present planned there will be
twelve wells delivering 100000 gall
Ions daily.
The Hanapepe pumping plant in
cludes a Worthington Vertical pump
capable of lifting 100000 of water a
day to the $50 foot level through a
"a inch pipe 800 feet long. The connec-
ton with the wells is now being made.
These wells with the normal flow of the
Hanapepe river will furnish 100000
gallons daily. The pipe from this pump
connects with a ditch 5 feet wide and
~ feet deep, 10000 feet long. From
IIllS ullCn 10 lile new Illll site are TWO
fumes 80 feet long, tunnel 290 feet
long and an inverted syphon 4S0 feet
long, "a inches in diameter and cross
ing the Wahiawa stream on bridge 80
feet long and 16 feet above the bed of
the stream. A short branch ditch leads
to a reservoir for storing the night wa
ter from the pump. The capacity of
| the reservoir is 100000 gallons. A
ditch from this reservoir 1900 feet long
will water land below the 200 feet level.
On the Laval side, a Riedler pump
of 100000 gallon capacity will be
completed by May IS.
The system of water supply from
running streams includes a ditch to
bring the water from the Wahiawa
stream to the $50 foot level ditch. This
ditch is 2,15O feet long, and the system
of which it is part will water all the
! land below the $50 foot level.
The main supply ditch for Eleele, on
the west side of Wahiawa stream is
about 1000 feet long. A ditch to bring
in the storm water of the Wahiawa
stream is $500 feet long including $50
feet of fluming and a tunnel 100 feet
long. This ditch empties it's water into
| Kawaihaka gulch, 672 feet above the
| large storage reservoir system. The
main supply ditch gathers all the wa
ters from the mountain ditch and the
| two tunnels and delivers it to the
| hlgheSJ OF the TWO storage reservoirs.
1t is 8 feet by 3. In connection with
the large storage reservoir system a
tunnel to tap the storm water of the
Wahiawa stream, 6 feet by in the
clear is now being cut. 1t will be 1906
feet long; $50 feet of it is completed
and it is advancing 10 feet a day.
The first of the large reservoirs fol-
storing the freshet water from Wahi-
ava stream has been completed. 1t has
a capacity of S0,000,000 gallons.
The pipe line system of the plantation
is extensive including 4,400 feet, par
of it of SO inch pipe.
Besides the water system, there Is
to be a complete railroad system m.
Guiding portable track. OF the latter
ten miles is now due to arrive. Eleelt
harbor has been selected for landing
and shipping merchandise and sugar
About two hundred and fifty acres OF
new land will be planted this year
This, taken with the five hundred
acres planted in Eleele, and one hun
bred and sixty-seven acres in Koloa
will make the crop from plant cane IL
the season of 1900 and 1901, nine hun
bred and seventeen acres. 1t is aimed
to plant two thousand acres for the
crop of 1912
The actual expenditures so far hav,
been Sal, 934.6 Sc.
