very shortly. The work will be handled as two
separate operations, the first covering the
excavation in the lower lock, and the second,
the removing of material from the channel
section. The lock excavation will be accom-
plished first.

It is estimated that in the total area there
are about 7,800,000 cubic yards that can be
excavated by the hydraulic method. The
material consists of a dark loam, containing
about 15 per cent of sand and some deposits
of gravel in the old bed of the Rio Grande.
The general elevation of the area is eight feet
above sea level, and the average depth to be
excavated is 35 feet. About 1,000,000 cubic
yards of the material will be required for the
core of the west dam at Miraflores; the re-
mainder will be discharged behind dikes
to the east of the Canal, thereby reclaiming
four hundred and fifty acres of land in the
vicinity of Corozal. It is estimated that a
fill of 15 feet or more will be made in this
manner. The amount of rock in the section to
be excavated is placed at 1,602,000 cubic
yards. When the hydraulic operations are
concluded, the pits that are opened up will
be pumped dry and the rock taken out by
steam shovels.

The old bed of the Rio Grande crosses the
area of hydraulic excavation in three places.
To keep the river water out, a diversion
channel, with a bottom width of 60 feet and a
grade of two-tenths per cent, was completed
over a year ago. It parallels the Canal at a
distance of about 300 feet from the mouth of
Cardenas River to about opposite where the
Rio Grande again enters the old French chan-
nel, near Station 2190. The diversion left
the prism practically free of surface water,
but during the rise of the tides, salt water
from the sea backed up regularly as far as the
basin at the lock site, which was formed by
the removal of material by the suction dredge
Sandpiper a year or more ago. As a prelim-
inary step in the hydraulic work at this point,
a coffer dam has been constructed below the
lock site, where the spur line from the Balboa
sand track to the pumping station crosses the
channel, thus preventing further entrance of
sea water from below it. At the north end
of the basin, a section of the original earth
will be allowed to remain separating the upper
from the lower locks. It was found that the
water left above this coffer dam was 25 feet
deep in places, and to bring the level down to
10 feet, at which depth the dredging units will
be able to operate to the best advantage, one
of the barge pumps has been set at work un-
watering the submerged area to the desired
level. This is done by pumping the water
through a 20-inch discharge pipe over the
dike east of the prism into the Rio Grande

When the second operation, that below the
lower lock, is begun, two more coffer dams will
be built, one across the old Rio Grande chan-
nel just north of the pumping station, and the
other across the Canal channel at the southern
limit of the section to be excavated, near
where the old channel of the Rio Grande

crosses the prism for the third time. This
will effectually shut off the entrance of water
from any direction, but water will continue to
back up from the Canal via. the Rio Grande
channel to the coffer dam north of the pump-
ing station, thereby furnishing a steady sup-
ply for the pumps.

The hydraulic plan involves two methods,
as follows:

(a) The disentegrating and sluicing of the
material into sumps, and

(b) The lifting and conveying of this disin-
tegrated material to the place of deposit with
dredging machinery mounted on concrete

The central pumping station, called "Agua
Dulce" from its proximity to Agua Dulce Hill,
lies west of the Canal, not far from the middle
of the territory to be excavated. The machin-
ery is inclosed in a temporary superstructure,
divided into an engine room 50 by 100 feet on
the east side, and a boiler room 40 by 100 feet
on the west side. The station floor is 12 feet
above sea level. The machinery equipment
consists of four 1,000-horsepower horizontal
direct-connected triple expansion pumping
engines, built by Henry R. Worthington,
with 19, 30 and 50-inch steam, and 24K->nch
water cylinders, and a 24-inch stroke. The
four units are lined up parallel to each other
at a distance of 25 feet from center to center.
Each pump is provided with a cast-iron 36-
inch suction pipe reaching, with the foot
valves, into a sump near by, excavated to
five feet below extreme low water. Each
engine has its own surface condenser,
built into the discharge pipe, and each con-
denser has a combination dry and wet vacuum
pump. At elevation plus 20,' the pumps dis-
charge into a common delivery pipe from
which they are separated by a 24-inch check
valve and a 24-inch gate valve. The delivery
pipe has two branches, which begin at the
outside, with a diameter of 24 inches, and
increase in size toward the center line of the
building, where they unite in a "Y" and con-
nect with the 40-inch discharge main. Each
unit is guaranteed to supply 7,500 gallons of
salt water per minute at 150 pounds pressure.

The boiler room equipment consists of four
Babcock & Wilcox water tube boilers of the
cross-drum, semimarine type, and each one
has 4,500 square feet of heating surface.
They are designed for 150 pounds pressure
per square inch without superheat and are
set in units of one each. The steam piping
is so arranged that any pump can be operated
by any boiler. On one side, the boilers have
oil furnaces; on the other side, fire doors,
grates and ash pits, so that coal can be used if
deemed expedient. The boilers are encased
in steel plates, instead of brick, protected by
magnesia and tile insulation. The steel stack
is 9 feet 6 inches in diameter and rises to a
height of 150 feet above the boilers. The
guaranteed efficiency from furnace to output
of the boilers is 95 million foot-pounds per
million B. t. u.

Fuel oil is stored in two steel tanks situated
on the side of the hill back of the station, each
tank having a capacity of 2,000 barrels. They
are directly connected with the Union Oil
Company's main, and the oil is fed through a
4-inch pipe, reaching the burners at a 50-
pound pressure.

The discharge main is 3,600 feet in length
and consists of 2,000 feet of 40-inch, 800 feet
of 32-inch, and 800 feet of 24-inch pipe. The
first 2,800 feet are lock-bar pipe, and

the remainder, spiral riveted pipe. The
lock-bar pipe, the product of the East Jersey
Pipe Company, was manufactured in 30-foot
lengths which are joined together by ? 4 -inch
forged steel flanges. Five air valves are
mounted at equal distances apart to prevent
rupture of the pipe and to allow the escape
of air while the pipe is being filled. The pipe
line is provided with 12 openings, in groups of
three, for the branch line connections. The
main extends nearly horizontally alongside the
approach track to the pumping station at the
foot of the Agua Dulce and Cocoli hills.
To prevent any upward movement it is
weighted down at regular stages by several
tons of rock. Where bends in the pipe occur
the latter is firmly anchored in place by
cables held taut by rings set in concrete. In
one place the pipe line crosses a wooden trestle
to which it is fastened by iron belt rods. Cor-
rosion is guarded against by the application
of an asphalt compound.

The branch lines, or "take-offs," are made
of 16-inch spiral riveted steel, the whole of
this class of steel pipe used on the works,
having been furnished by the Abendroth &
Root Manufacturing Company of Newburgh,
N. Y. Each branch line consists of a section
of twin pipe 800 feet long extending to the
monitors or giants, the four double lengths
thus employed aggregating 6,400 feet. They
are situated 800 feet apart, the first one
branching off at a point 1,200 feet from the
central pumping station. The arrangement
is such that one of the branch lines can be
made to serve, if necessary, as an addition
to any one of the others, thereby extending
the immediate zone of operations.

The hydraulic giants or monitors were made
by the Joshua Hendy Company of San Fran-
cisco and are of the latest type used in mining
operations in California and other parts of the
West. Each of the eight giants weighs 1,500
pounds and consists of a base for attachment
to a 16-inch gate valve at the terminus of the
pipe line, a horizontal and vertical joint, and a
long conical reducing piece. The frictional
resistance is decreased by a ball-bearing, and
a weighted lever is attached to control the
direction of the jet. A deflecting nozzle
is fitted to the discharge end of the giant,
which permits deflections through a small
angle without changing the position of the
main body. The tapering piece of the giant
is fitted on the inner side with two sets of
guide vanes which prevent a scattering or
rotary motion of the water after it has issued
from the nozzle. The nozzles used will vary
from four to six inches in diameter according
to the charactaipaf the material in which they
are working, and at full head the water coming
through thedi avill exert a pressure of 130
pounds to the square inch, the equivalent of
a ton and one-half of pressure against a bank
100 feet away within range of the deflectors.
As it is expected that the positions of the
monitors will be shifted frequently their bases
are of temporary construction. The giants
will operate from eight feet above to 45 feet
below mean tide, and will be made to wash
down the material in sluices which will carry
the water containing earth in suspension to
the sump where the barge pumps are at work.
When it becomes necessary to move a barge
the giants will cut a new sump with a channel
leading into it through which one or more
units of the fleet may be floated. The banks
will be excavated as nearly perpendicularly

as possible, in order that I inches may be cut
in them and the banks undermined so as to
cause the material to fall by gravity.

The centrifugal dredging pumps correspond
in total capacity to that of the steam recipro-
cating pumps, and are mounted on barges
built of concrete, one unit or pump to each of
the three barges. A description of these
barges was published in The Canal Record
of February 9, 1910. Each unit consists of
an lS-inch single suction dredge pump direct-
connected to a Westinghouse 655-horse-
power induction motor. The runners for the
pumps are overhung and are especially long.
The manganese steel impeller on each pump
has five blades and is designed to handle
10,000 gallons of salt water per minute and
300 cubic yards of solid matter per hour, or,
in other words, 110 cubic feet of water to one
cubic foot of sedimentary material against a
varying actual head up to 60 feet while run-
ning at 480 r. p. m. Each pump, including
base plate elbow and valve, weighs approxi-
mately 30,000 pounds. The suction pipe on
each pump is 12 feet long and 20 inches in
diameter. The motors are of the 3-phase,
25-cycle type, 2,080-volt, with automatic
starting equipment. On the switchboard
panels are mounted indicating and integra-
ting wattmeters, oil-circuit breakers and the
time limit switches. Power will be supplied
by the Miraflores central station, and armored
submarine cables connect the motors to the
pole lines. For priming the pumps, a small
motor-driven vacuum pump will be installed
on each barge.

The crest of the dam at Miraflores will be
70 feet above sea level, making the total lift
for the hydraulic fill, 110 feet. The dredging
pumps will accomplish the lift to 60 feet, and
to secure the additional lift of 50 feet, an
18-inch motor-driven relay pump, identical in
type to the centrifugal dredging pumps, has
been installed in a small pumping station on
the west bank about midway between the
dam and the central pumping station, and
will be attached to one of the dredging units,
being so arranged that the 20-inch suction
pipe may be directly connected to the dis-
charge pipe of the dredging pump. The
discharge pipe to the core of the dam has been
completed, with the exception of a small gap
which can be closed in a few hours.

Clerk and Typewriter Examinations.

It is desired to direct attention to the fact
that typewriting is no longer given as an
optional subject in connection with the exam-
ination for clerk, Isthmian Canal Service.
Optional subjects which may be taken in
connection with that examination are stenog-
raphy and typewriting, bookkeeping, rail-
road experience, general business experience,
and timekeeping experience.

A separate examination will be held for
typewriter, Isthmian Canal Service, which
will comprise the following subjects, with
relative weights on a scale of 100 as indicated:
Copying from rough draft, 20; copying and
spacing, 30; copying from plain copy, 20;
penmanship, 5; report writing, 10; arithmetic
(first grade), 5; general business experience,
10. - The last subject will be rated on the
statements made in application and testi-
monials, corroborated, if necessary, by persons
named as references. It is expected to secure
from this examination eligibles qualified in
typewriting and having a general business

experience. Appointments will be made to
the position of clerk at §1,200 per annum.

Examinations for clerk and for typewriter,
both for the Isthmian Canal Service, will be
held on Sunday, September 18, as announced
in last week's Canal Record. Information
and application blanks may be secured by
addressing the undersigned.

Printing Plant Monotype.

A monotype equipment, consisting of a
casting machine, No. 2751, and a keyboard,
No. 3808, manufactured by the Lanston Mon-
otype Machine Company of Philadelphia, has
been installed in the Commission printing
plant at Mount Hope. It does the work of
several compositors and will compose type
from 5 to 12-point any width up to 60 picas,
and will cast type from 5 to 36-point. The
Commission equipment contains two 8-point
molds, one each, 6, lOand 12-point molds, with
the same number of matrix cases containing
matrices for 225 different characters, two
adjustable molds to cast from 14 to 36-point
type, inclusive, and a number of sort matrices.
