NOTES OF PROGRESS.



Central Division Excavation.

The excavation in the Central Division
in June was 1,433.30-1 cubic yards, which
makes the total for the fiscal year 18,479.642
cubic yards, the largest fiscal year excavation
on record, exceeding the best previous, that
of 1909, by 37,018 cubic yards. This total
includes Culebra Cut. concerning which, an
article is published elsewhere in this issue, and
the Chagres River section, where the bulk of
the work was ended in March, and in which
there has been but little done to swell the
yardage during the past three months. At
present, there are only two pieces of work in
progress in this section, viz., where contractors
are excavating at Gorgona and Bohio, the
total for the former place in June being
11,216 cubic yards, and for the latter, 21,072
yards.



New Filtration Plant at Gatun.

The new filtration plant for the Agua Clara
water works at Gatun is completed, with the
exception of the exterior and interior stair-
ways and a small amount of work remaining
to be done on the sedimentation basin, and
the installation of the piping system. The
latter has been purchased in the States, and
will probably be delivered on the Isthmus
within the next thirty or forty days.

The filter building is of reinforced concrete,
41 by 54 feet in size, and three stories high. On
the first floor will be located the controllers
and the general pipe system; the second floor
supports the valve stands for controlling the
piping system, filter tables, and gives access
to the tops of the filters. The third floor
provides storage room for the aluminum
sulphate supply. The concrete work is ap-
proximately 95 per cent completed. The con-
tract for most of the piping, controllers, and
regulators, and loss of head gages, air com-
pressors, and hydraulic valves, was awarded
to the American Water Softening Company.

During the time which will elapse before
the plant will be ready for operation, a small
experimental filter will be set up at the Mount



Hope pump station, adjacent to the sedi-
mentation basin at that place. Water from
this basin will be used in the experimental
filter for the purpose of determining the grade
of sand most suitable for the filter beds in the
new filter plant at Gatun, as well as for the
pressure filters at Mount Hope. Chame sand,
Porto Bello sand, and a- much coarser and
sharper grade of sand from the vicinity of
Chorrera will be experimented with.

In addition to the filtration plant at Gatun,
a laboratory building of reinforced concrete,
having a floor plan of approximately 20 by 20
feet will be erected for conducting analyses
of water to determine the amount of alumi-
num sulphate to be used in connection with
the water supply for both the Agua Clara
and the Brazos Brook reservoirs.



846 Tons of Dynamite in Single Shipment.

The largest cargo of dynamite ever brought
to the Isthmus on one vessel was unloaded
from the Munson Line steamship Aim, which
arrived at dock No. 14, Cristobal, on June 27.
The shipment consisted of 29,363 cases, the
contents of which aggregated 1,691,191
pounds, equivalent to about 846 tons, and
was applied on the requisition for explosives
placed in the United States for the fiscal year
ending June 30, 1911. The shipment, divided
into its various classes, is given below:

Kind. No. Cases. Pounds.

60 per cent saltpetre dynamite. . . 8.105/ ... ]0]
45 per cent saltpetre dynamite. . . 3.758 j txo.ivi

60 per cent Atlas dynamite 8.000 464.000

45 per cent Atlas dynamite 9,500 551.000

Total 29,363 1.691.191



Freeing Cocoli Lake of Chlorine.

The chlorine content in Cocoli Lake, caused
by salty water leaking through a toe of the
west dam at Miraflores, has been reduced
since early in April, when an analysis showed
1,950 parts of chlorine to a million parts of
water. On May 3, an analysis showed 480
parts of chlorine to a million of water, both
at the lake surface and at the intake, which
is 10 feet below the surface, while at the
Ancon filter, after the lake water had become
mixed with the flow from the Rio Grande
reservoirthe content was 180. A Iateanalysis,
that of June 24, showed but 220 parts to the
million on the lake surface and at the intake,
and only 120 parts at Ancon filter.

An 8-inch, motor-driven centrifugal pump
was installed on the bank of the lake in April
to remove as much as possible of the salty
water. It wa^ operated with good results, but
when the break occurred in the temporary
spillway in the Miraflores dam on May 24,
the pump was removed to the lock site to
assist in freeing the pit of the flood water. It
is now proposed to install at Cocoli Lake, in
place of this pump, one of the four 20-inch
dredge pumps, purchased for use in connec-
tion with hydraulic operations, and thus
hasten the work of ridding the lake of its
chlorine content. The pump will probably



be ready for service this week, and as its
maximum capacity is about 10,000 gallons a
minute, it is expected that a month's opera-
tion of it will be sufficient. There has been
no further leakage from the hydraulic fill
through the toe of the dam into the lake.



Culebra Cut Transportation.
A new incline into Culebra Cut, between
Paraiso and Cucaracha, on the east side of the
Canal, is about to be constructed. It will
utilize the 95-foot berm part of the distance.
By means of this new track, trains which now
enter the Cut by way of the Contractor's Hill
incline, on the west side of the Canal, and
shift back and forth in order to reach the
shovels on the east side, south of Gold Hill,
will save considerable time in entering the
Cut, and the amount of spoil hauled out each
day will be increased by several hundred
cubic yards



Buoys Near Pacific Entrance.

Two mooring buoys have been received on
the Isthmus by the Panama railroad and will
be placed near the south end of the wharf
at Balboa. They are to be anchored at this
point, in order to permit United States and
other vessels to coal from lighters under more
favorable conditions than at the present
anchorage, east of Flamenco Island, and to
lessen the danger tcthe lighters on account ot
heavy weather. The new buoys are 1 2 feet in
diameter, 10 feet deep, and are complete with
fenders, etc. They will be anchored in position
by six mushroom anchors, each weighing about
4,000 pounds, and connected by a total of 1.200
feet of l|-inch short link chain. They are the
largest buoys now in these waters, and when
placed on a flat car for transportation across
the Isthmus, overlapped the required clear-
ance in passing trains on the Panama railroad
double track line by about two feet six inches,
necessitating a specially arranged trip.

Six mooring buoys, each eight feet in
diameter, and nine feet deep, were received
by the Pacific Division on February- 18, for
marking purposes. Two of these have been
placed at Punta Chame, two at Naos Island,
near the place where the suction dredge
Culebra is beached when extensive repairs are
made to the vessel, and two are in stock.



Work at Cristobal Marine Shops.

The work at the Cristobal drydock shops
on July 1 included repairs to seven vessels,
and the construction of two derrick barges, a
description of which appeared in The Canal
Record of May 24. One of these barges was
launched on Thursday, June 15, and with the
exception of building the boiler house, work
on it is at a standstill pending the arrival of
the engine equipment. Work on the shear
legs and the boom of the derrick equipment is
under way, and the boom base castings,
manufactured at Gorgona shops, are being

machined and finished at the marine shops.
Structural work on the other derrick barge
has been started at the marine ways.

Dredge No. 5, which has been given a
general overhauling, will go into commission
again this week, replacing dredge No. 6,
which sank in the Canal, near Mindi, on
June 19. The dipper dredge Chagres is re-
ceiving a complete overhauling, and, in
addition, is being fitted with a new boom of
the type carried by the dredge Mindi, to-
gether with a new turntable and base casting.
The Panama railroad tug Phoenix, barges
Nos. 5 and 14, and scow No. 112, are being
thoroughly overhauled, the work including
renewal of the combings, repairs to the towing
machines on the barges, and the repainting
of all the vessels.

New Home of University Club.

Plans have been completed for the new
clubhouse of the University Club in Panama,
the majority of whose members are Canal
and Panama railroad employes. The building
will be situated on property recently purchased
by the club, on the peninsula upon which
the walled section of the city was situated.
This site is immediately back of Las Bovedas,
the old fort and prison, commonly known as
"the sea wall," and the building will front
upon an arm of the bay looking towards
Balboa, and Ancon Hill. The Spanish mission
style has been followed in the plans, and it is
proposed to finish the interior in the same
style. The building will be 106 feet long, 42
feet wide, and two stories high, with light on
four sides. A recessed entrance will lead into
a center hallway, from which steps to the



second floor will branch off near the entrance,
so that persons wishing to use the library, or
the ladies' rooms, may do so without passing
through the men's part of the house. On the
ground floor will be billiard and card rooms,
a grill and cafe\ kitchen, pantry, store room,
and dining room, the last named looking out
upon First street and the sea wall. On the



second floor, will be the library, and dining
and retiring rooms for ladies. This floor
will be so arranged that it may be cleared
for dancing, leaving a ballroom about 40 by 75
feet. The plans and specifications may be
seen at the store of Vibert and Dixon on Central
avenue in Panama. It is expected that the
bids will be opened the last week in July.
