same has been addressed, the furnishing of tug service
to them will be on the alternative basis recommended
by the committee above referred to. to-wit:
"That tug boat service not in conformity therewith
(as contained in notice above) shall be furnished only
after an agreed price is arranged, based on the con-

NOTES OF PROGRESS.
Slides in Culebra Cut.
On July 4, a mass of earth and soft rock
on the east side of Culebra Cut at Culebra,
immediately north of Gold Hill, fell into the
Cut, and so covered steam shovel No. 225
that only the end of the boom is sticking out
of the mass. The movement occurred early
in the morning, and no one was injured by
it. It is not known how badly the shovel was
damaged, because it is not yet freed from the
slide. Another steam shovel is excavating the
material to the end that shovel No. 225 may
On July 10, the mud slide on the east side
of the Cut at Las Cascadas, having become
saturated by the rain, moved into the Canal
prism, blocking all tracks on the east side of
the center drainage ditch, and thus reducing
the output from the north end of the Cut.
The total amount of material in motion,
or about to move, into Culebra Cut, does not
exceed the estimate of excavation yet to be
done there, as indicated elsewhere in this
Freshet of July 5 and 6.
On July 5 and 6, a freshet in the Chagres
River reached the following elevations:
Garaboa 44 .
The estimated discharge at Alhajuela, at
the crest, was 37,200 cubic feet a second, and
at Gamboa, 34,500 cubic feet a second.
Canal Work in June.
The grand total of Canal excavation to
July 1 was 142,967,554 cubic yards, leaving
to be excavated 39,570,212 cubic yards, or
less than one-fourth of the entire amount for
the completed Canal.
The total for June was 2,646,442 cubic
yards, as compared with 2,616,609 cubic
yards in June, 1910, and 2,895,793 cubic yards
in June, 1909. All the excavation was "work
excavation," there being no "plant excava-
The dry excavation amounted to 1,588,388
cubic yards, and was principally by steam
shovels. The dredges removed 1,028,198 cubic
yards, and 29,856 cubic yards were sluiced, in
addition to the amount pumped into Gatun
Dam by suction dredges. The progress on
the locks at Gatun, Pedro Miguel, and Mira-
flores is referred to elsewhere in this issue.
In the Atlantic Division, the total excava-
tion was 516,095 cubic yards. Of this total,
63,997 cubic yards were dry excavation, and
the remainder was removed by the dredges
in the Atlantic entrance.
The total excavation in the Central Divi-
sion was 1,433,304 cubic yards, all of which
was from the prism.
In the Pacific Division, the total excavation
was 697,043 cubic yards, 522,242 cubic yards
of which were taken out by the dredges at
the Pacific entrance, and 53,858 by the
hydraulic excavation plant at Miraflores

such as Prism. Diversions, or Locks, etc.: that is. it
represents miterial taken from the area to be occu-
pied by the Canal, and constitutes excavation useful
for the completed Canal.
By "Plant" Excavation is meant excavation outside
of any of the constituent parts of the Canal, such as
Prism, Diversions, or Locks, etc. It includes mate-
rial necessary to be excavated for construction pur-
poses only and is chargeable against the particular

Construction of Naos Island Breakwater.
During June, an average of about 1,000
cubic yards of material from Culebra Cut
was dumped on the Naos Island breakwater.
In order to complete the breakwater to the
island before the spoil available from Culebra
Cut will be exhausted, it will be necessary
to dump on an average about 3,500 cubic
yards daily. A committee has been appointed
to determine upon a method of accomplishing
this end, consisting of Messrs. S. B. William-
son, W. G. Comber, M. W. Tenny, and W. T.
Reynolds, representing the Pacific and Cen-
Draining Culebra Cut Through Pedro Miguel
Drainage from the south end of Culebra
Cut will, henceforth, pass through the culvert
in the center wall of Pedro Miguel Locks.
Excavation was completed on July 12, con-
necting the pioneer shovel cut in the south
end of Culebra Cut with the culvert at
elevation 28 feet above sea level, 12 feet
below the bottom of the Cut. All the water
drained south from the summit between
Culebra and Empire, which heretofore has
passed through the site of Pedro Miguel
dam, will pass through the culvert, which has
a diameter of 18 feet. This will ensure quick
drainage of the Cut, and will also enable the
Pacific Division forces to complete the dam,
work on which could not be finished while
the drainage was passing through the site.

Compressed Air Leakage.
A series of tests has been made of the air
mains in the Central and Pacific Divisions
to determine the amount of waste from all
causes, and the proportionate share of the
cost that should be borne by each division.
It was found that there was practically no
leakage in the main between the Rio Grande
compressor, and the beginning of the Pacific
Division lines. On June 11, a test of all the
mains and laterals showed a total loss of air
of 24.89 per cent on the basis of the output
for May, of which only 5.8 per cent was on
Pacific Division lines. At the time of the test,
the flow of air into the Pacific Division mains

was measured by a meter. It has been deter-
mined to cut out all laterals for the Pacific
Division, north of the flow meter, and, since
there is practically no leakage between the
compressor plant and the meter, the propor-
tion of cost of air compressing to be borne
by the Pacific Division will be determined by
the flow through the meter.
Electric Flat-irons for Ancon Laundry.
The Ancon hospital laundry will be equipped
with electric flat-irons, replacing the ordi-
nary ones heated over gasoline burners,
now in use. They include ten 6-pound, fifteen
7-pound, and twenty 8-pound flat-irons,
aluminum finish, each fitted with a cartridge
unit, and a detachable wooden handle. In
addition, six extra cartridge units for the
6-pound irons, six for the 8-pound, 12 extra
attaching plugs for the 6-pound irons, and
12 for the 8-pound, together with 1,000 feet
of No. 12 two-conductor heater cord, have
been furnished. Current from present electric
light wires will be used. The new method
is expected to increase the efficiency of the
plant, and to lessen the operating cost.
Gatun Dam Spillway.
The concrete work in the spillway of Gatun
Dam is over 64 per cent completed, 144,193
cubic yards, out of a total of 225,000, having
been placed at the close of work on July 8.

Additional Mixers at Mlraflores Locks.
The concrete output in the upper lock at
Miraflores will be increased by the placing in
operation, this week, of an auxiliary mixing
plant, situated in the east wall. It consists
of two 2-cubic yard mixers, formerly in use
in the east storage trestle at Pedro Miguel.
The output from this plant will be utilized
in the construction of the center wall, and
will be handled in buckets and conveyed by
the narrow-gage equipment to the chamber
cranes, which will lift it into place. The
method of transportation is similar to that
employed at Pedro Miguel, except that the
operation of the narrow-gage equipment, as
well as that of the cranes, will be confined
to the east chamber, the cantilever arms of
the latter having sufficient reach to carry on
the construction of both sides of the wall.
In building the center wall in the lower lock,
it is proposed to continue the use of the
auxiliary plant in its present position, and to
extend the narrow-gage track into the lock
by means of an incline. It is expected that
the additional mixers, when running at full
capacity, will increase the output at these
locks from 800 to 1,000 cubic yards a day.
The third berm crane at the upper lock,
completing the two on the west bank, will be
ready for operation this week. It will be
used primarily in excavating a projecting
section of the west bank at the upper end of
the lock. Seven steam shovels are now exca-
vating in the lower lock.
CONCRETE WORK IN THE LOCKS.
Over 56 per cent of the concrete for all the locks is in place, the amount at the close of
work on July 8 being 2,413,616 cubic yards, out of a total of approximately 4,284,400. A
total of 23,424 cubic yards of concrete was laid in the locks during the week ending July 8.
Over 69 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 8 being 1,443,415 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 8, 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
