NOTES OF PROGRESS.^

Revised Estimate of Excavation.

Elsewhere in this issue, there is published
an article on the slides in Culebra Cut,
giving the figures of the new estimate, as
of July 1, for excavation in the Central
Division, made necessary because of these
slides. By error, the amount of additional
excavation on this account, as published in
the report for June of the Chairman and
Chief Engineer, in the issue of The Canal
Record of July 19, was given as 2,571,690
cubic yards, instead of 4,676,278 cubic yards.
That section of the report should have read:

"On account of the changes in the stability
of the Canal banks in the Culebra section
it was found necessary to add 4,676,278 cubic
yards to the original estimate for completed
Canal, making the revised total estimated
amount of material to be removed in the
Central Division 101.801,296 cubic yards,
and up to July 1, 1911, 77,338,235 cubic
yards had been removed, leaving 24,463,061
cubic yards yet to be removed, in order to
complete all excavation in the Central Divi-
sion. From these figures it will be seen that
75.97 per cent of all excavation in the Central
Division has been completed up to the close
of the month of June, and 24.03 per cent yet
remained uncompleted.

"Considering the two sections which com-
pose the Central Division, the excavation
completed, and that yet to be completed,
at the close of June operations were, as follows:
Culebra Section. Cu. Yds.

Completed 65,514.865

To be completed 23.929,140

Chagres Section. Cu. Yds.

Completed 11.823,370

To be completed 533,921

"From the above figures it will be seen that
the Culebra section, locally known as Culebra
Cut, is 73.25 per cent completed, and 26.75
per cent yet to be completed. The Chagres
section is 95.68 per cent completed, and 4.32
per cent yet to be completed."

Concrete Revetting in Culebra Cut.
Four tests are being made at Contractor's
Hill, in Culebra Cut, to determine the most
economical and effective method of concrete



revetment. The first method is to place rail
against the side of the soft rock on 3-foot
centers, covering a space about 20 feet broad,
and then cover the rail with concrete. The
second method is to place one inch square
rods, 2 feet 6 inches long, in the soft rock on
3-foot centers, and to anchor the revetment
of concrete to the rock by these rods. The
third, is to place the concrete against the rock
in forms, but without puddling it to make
a smooth surface, and then to finish the
surface with the cement gun, this method
to use neither reinforcement nor anchorages.
The fourth method is to continue with the
work of coating the soft rock by means of the
cement gun.

The purpose is to determine the kind of
protection to use in covering the decomposing
rock below the 95-foot level in Contractor's
Hill, and at other points along the Canal.
Chagres River gravel which is mixed with
sand in proper proportion, and one barrel of
cement to the cubic yard of material, are used
in making the concrete.



Coal Contract.

The annual contract for furnishing up to
550,000 tons of semibituminous coal for use
by the Commission and railroad on the
Isthmus has been let to the Pocahontas Fuel
Company at S2.51 per gross ton, f. o. b.
steamer; and the contract for carrying this
coal to the Isthmus has been let to the Earn
Line Steamship Company at $1.29j per ton.



Canal Work in the Mlndi Section.

The construction of the dike, east of the
Panama railroad right-of-way, between New
Gatun and Mindi station, for the retention
of material to be excavated hydraulically
from the Canal prism, north of Gatun Locks,
will be completed within the next few days.
It consists of a trestle fill, which parallels the
Panama railroad for a distance of about 4,000
feet, with a line extending at nearly right
angles from each end to higher ground. The
dike forms an enclosure of the low ground in
this vicinity, with an inside area of several
hundred acres, and will be capable of re-
taining a fill about 20 feet in depth, the water
from it draining off into the Mindi River.
The spoil is obtained from the dry excava-
tion below sea level at Mindi.

It is expected that the hydraulic fill of the
city of Colon will be completed this week,
and dredge No. 86. which has been employed
in this work, will be returned, after a thorough
overhauling at the Cristobal drydock, to its
former position in the borrow pit, north of
the Gatun Dam, where it will resume opera-
tions on the hydraulic fill of the Dam, dis-
placing the Sandpiper. The latter will be set
at work north of Gatun Locks to begin the
excavation toward Mindi, and also the
removal of the earth dike, which forms a
barrier between the upper lock and the
anchorage basin. About the first of Novem-



ber, the Sandpiper will be joined by dredge
No. 4, now engaged in dredging sand at
Nombre de Dios.

Two steam shovels are at work at present
in the pit at Mindi, and the excavation is
down to grade in several places. The work
there will probably be completed before the
end of the year.



Vessels to Carry Cement.

The contract for furnishing ships to carry
cement, in addition to that carried by the
Ancon and Cristobal, has been let to the Mun-
son Steamship Company for SI. 84 per gross
ton, as compared with $1.70 per gross ton
under the former contract. Three bids were
received, the other two being $1.87 and $2,
respectively. The new agreement became
effective July 1, and is for three or six
months, at the option of the Commission.



Lubricating Oils and Greases.

The contract for lubricating oils for the
fiscal year 1912 has been let to the Texas
Oil Company, the amounts estimated and
prices bid, less the rebate allowed for return
of containers being, as follows:

total contract price S45.258.63.



Work on New Balboa Docks to be Hastened.

Work on the new Panama railroad dock at
Balboa is now going forward with day and
night shifts, in order that its construction
may be hastened The new schedule went
into effect on Monday July 17, the day
shift working from 7 a. m. to 5 p. m., and the
night shift from 6 p. m. to 3 a. m. Owing to
a lack of lighting facilities, the night work
so far has been principally confined to freeing
the caisson pits of water, and removing the
excavated material. Alighting circuit is being
strung, and within a few days, the night force
will be considerably augmented, and opera-
tions extended to all phases of the work.

On July 24, twenty-seven out of the 53
caissons required for the foundation of the
dock were under way. Of this number, nine
had been sunk to bed rock, and six of them
had been filled with concrete. Several more
had been excavated to nearly the required
depth, and the work is now in progress at
various points for the entire length of the
dock. In sinking the caissons at the north

end, some difficulty was experienced from the
unusual amount of water and the peculiar
formation of the ground encountered, the
latter consisting of soft mud underlying a
clay of much harder quality, causing some
interference with the setting of the caisson
structures.

Part of the excavation for the caisson pits
is done with bucket and shovel, and part by
a crane operating a clam shell bucket. All of
the concrete sections of the caissons, with the
exception of the base portions, are built on the
bank nearby, and transported into place by
crane. Three mixers, two 5-yard, and one
1-3 yard, supply the concrete. In addition,
two locomotive cranes, and 14 drilling
machines, are in service, the latter furnishing
the motive power for hauling the buckets
of mud out of the pits.



Gatun Dam Spillway.

The concrete work in the Spillway of Gatun
Dam is over 65 per cent completed, 146,822
cubic yards, out of a total of 225,000, having
been placed at the close of work on July 22.

day last week, and of the total in place,

Sunday Trips to Toro Point.

Beginning last week, the limit of passes
issued to employes and their families who
desire to spend a Sunday at Toro Point was
raised from 40 to 100. Until recently, a clapet
was used to carry the excursionists, and its
accommodations provided for about 40
people. Under the new arrangement, the trip
is made by tug, and increased passenger room



is available. The demand for passes was
always greater than the supply, which usually
became exhausted early each week, and even
the increased allowance of transportation has
been followed by an increased demand, so
that practically the entire allotted number
of passes were issued for Sunday, July 23.
Since the life protection measures were insti-



tuted, the bathing beach has proved a greater
attraction.

Pilots, Masters, Mates, and Engineers.

The Board of Local Inspectors will examine
applicants for licenses as pilots, masters,
mates, and engineers, on Wednesday, August
2, at 9 a. m., at the Administration building,
Ancon.



CONCRETE WORK IN THE LOCKS.



Over 58 per cent of the concrete for all the locks is in place, the amount at the close of
the work on July 22 being 2,476,271 cubic yards, out of a total of approximately 4,284,400.
A total of 32,140 cubic yards of concrete was laid in the locks during the week ending July 22.

GATUN LOCKS.

Over 70 per cent of the concrete for the system of three twin locks at Gatun has been
laid, the amount in place at the close of the work on July 22 being 1,479,273 cubic yards, out
of a total of 2,085,000.

A statement of the amount of concrete placed in the locks each working day for the week
ending July 22, and of the total, follows; and a similar statement for the work in the Spillway
of Gatun Dam is published elsewhere in this issue. The construction plant works 12 hours
daily, and the auxiliary plant 9 hours.

CURUNDU RIVER DIVERSION.

Manner in Which the Swampy Area Contiguous
to Panama is Being Drained.

Work on the Curundu River diversion,
which is designed to drain the swamp lands
bounded on the north by Diablo Hill, on the
east by the rising ground of the Sabanas, on
the south by the track to Balboa, and on the
west by the toes of the old Sosa-Corozal dam,
is in progress. When the fill for the toes of the
dam was first started, about four years ago,
the natural outlet of the Curundu was
blocked, and since then, the only place of
escape for the surplus water in the swamp
has been over a dike about four feet above
sea level at mean tide, into the diversion
ditch which crosses the old Balboa wagon
road, near the East Balboa hotel. This would
allow the water to run off only at overflow
periods, and would keep the tidal streams and
low places filled at other times. In the past,
the swamp has acted as a receptacle for the
streams flowing across the Panama railroad
right-of-way, south of Diablo Hill, which
have a watershed extending back into the
Sabanas. This formed a vast breeding place
for mosquitoes, and the present work is, there
fore, a sanitary measure.

The west toe of the old dam has been cut
through, thus allowing the water from the
Curundu to flow into the Rio Grande, near
the site of the half-submerged old French
dredges. The excavation is being accom-
plished by means of an orange peel dredge,
which is pushed along on skids, and by hand
work. The dredge is now engaged in making
a cut through the east toe of the dam, and
from this point, channels will be extended in
two directions, one to connect with the Rio
Hondo, a small tidal stream, and the other
to carry' off the water from a tidal estuary,
which winds tortuously about the flats, and
constitutes one of the largest of the swamp
waterways. About 1,500 feet of channel, in
all, will have to be excavated to an average
depth of four feet below mean tide. The bot-
tom width varies from 10 to 15 feet, depending
on the amount of water to be carried off. As
the material for the most part is very soft,
and slides easily, the banks of the channels
are made to slope back, so that at the top, their
width is 25 feet, or more, and, in time, the cur-
rents will probably cause a further widening.

When the system has been completed, the
entire swamp will be drained of water at low-
tide, the work so far accomplished having
lowered the old level considerably, tracts of
land, formerly under water at low tide, being
high and dry under the changed conditions.
The work it is believed, will improve sani-
tary conditions in the district of Guachapali,
in Panama, and will result in a sanitary
saving. One instance of this, is the section
of swamp occupying the triangle between the
Panama railroad main line, the Balboa track,
and the Balboa wye, which will be drained
sufficiently to permit of cutting grass with a
mowing machine, instead of scythes.

The Central Division is making a fill of the
low lands near the East Balboa commissar)-,
which will reclaim 66 acres of ground. The
diversion ditch, which extends through this
swamp, will also be filled, as, under the new
drainage system outlined above, there will be
no further use for it.
