NOTES OF PROGRESS.

Canal Bridge Project Abandoned.

The board appointed by the Chairman to
consider the question of the erection of a
permanent bridge over the Canal, and which,
in November, 1910, made a preliminary report
favoring the construction of a bridge of the
high, fixed type at Empire, has reconsidered
the subject, and has submitted another report
and recommendation to the effect that the
project be abandoned. The action of the
board has been approved by the Chairman
and Chief Engineer.

In reaching its later decision, the board
gave consideration to a number of develop-
ments that have occurred since the framing
of its original report. One of these was the
lessened necessity for a bridge to provide
railway facilities. The survey of the Panama-
David railroad, as made by the Panama
Railroad Company, planned to have the new
line cross the Canal in the vicinity of Empire.
This arrangement has since been changed by
the Panama Government, and it is now pro-
posed, in case the road is built, to bring it to
the Pacific slope, outside of the Zone line,
connecting with Panama from this point by
ferry.

Another reason that had considerable
weight was the increased cost of a high level
bridge, due to the increased amount of fill
required to connect the east approach with
the relocated Panama railroad. At the time
the committee made its first report, no com-
plete data were available on the Isthmus,
and a clearance height of 175 feet above
minimum sea level was tentatively taken as
the basis of the committee's calculations.
Since then, a change has been made in the
alignment of the relocated line around Gold
Hill, which has removed the tracks further
away from the Canal in the vicinity of
Empire. In addition, data received from
various official sources, and from the different
steamship lines and builders, both in the
United States and abroad, indicate that a
clear height of 175 feet would not be sufficient
for the fixed wireless masts of the largest



existing steamships, some of which would
require a clear height of 212 feet.

In order to give the people living west of
the Canal suitable means of communication,
after rail connection over the canal is inter-
rupted, the board favors the operation by the
Panama railroad of an independent shuttle
train service on the west bank, between a
point approximately opposite Pedro Miguel,
and as far north as the waters of Gatun Lake
will permit, the transfer of passengers and
freight across the Canal to be provided for
by barge or ferry boat. The board also favors
the construction of inclines to the 95-foot
berms on each side of the Canal at one or
more intermediate points for convenient access
by foot passengers, horses, carts, etc., so that
the transfer at such intermediate points can
be made, if necessary, at any time by small
boat or barge.

High Steam Shovel Average in Empire District.

On May 23 1911, seventeen steam shovels
working in the Empire District excavated
25,999 cubic yards, or an average per shovel
of 1,529 cubic yards, almost all rock, and
difficult to handle.

This is the highest average per shovel in
this district during the present fiscal year,
the next highest being on March 31, 1911,
when 20 steam shovels excavated 29,279 cu-
bic yards, or an average of 1,464 cubic yards
per shovel.

Old Ship at Nombre de Dios.

A second wreck has been found by the
suction dredge which is excavating sand for
Gatun locks at Nombre de Dios, an old hull
at a point about 250 feet inside the shore
line and 20 feet below the surface of the
ground. No effort has been made to takeout
the hulk, because the dredge operates easily
over it, but it appears to be about 100 feet
long. The pumps have drawn up a small
figurehead of brass, an iron pestle, and a
large number of lead bullets from three-fourths
to two inches in diameter. A similar hulk
was unearthed in September, 1910.



Life Line at Toro Point Beach.
The bathing beach south of Toro Point is
used to a large extent by employes of the
Commission residing at the settlement, and at
points along the Panama railroad, particu-
larly on Sundays. There is at times a strong
undertow in the water off the beach, and it is
believed thac unless some form of protection
is arranged, loss of life may occur. To avoid
this danger, some old French rail will be
jettied in the sand, and connected with dis-
carded wire cable in a manner that will afford
the desired protection. An expenditure of
$150 has been authorized for the purpose.



train from Colon, provided proper authority
is exhibited in each case. This arrangement
is made to facilitate the transfer of transporta-
tion and steam shovel men from Bas Obispo
and Las Cascadas to other points in the divi-
sion. In case an engine is left without an
engineer at Pedro Miguel, it will now be possi-
ble to supply a man from Las Cascadas in
time to take the locomotive out practically
on its scheduled leaving time.



Telephone Notes.

The central telephone exchange at Cris-
tobal has been moved from the building in the
rear of the police station, to the upper floor
of house No. SO, near the Roosevelt avenue
railroad crossing. The change was made
necessary by the work in connection with the
new dock system.

The permanent telephone line along the
Panama railroad relocation has been com-
pleted between Monte Lirio and Frijoles, and
the construction force is now at work extend-
ing it south toward Caimito. It is proposed
to put another new crew to work within a
few days building the line from Gatun south
to Monte Lirio.



Transportation on Commissary Train.

Employes of the Central Division will, in
cases of emergency, be permitted to ride on
train No. 1, the early morning commissary



Miraflores Locks Flooded.

The temporary spillway, which provides an
outlet for the water in the hydraulic fill of the
west dam at Miraflores, was undercut on
Wednesday afternoon. May 24, and a torrent
of silt and water rushed through the enlarged
opening, the most of which found its way into
the upper lock, about 100 yards distant,
flooding it to a depth of three feet over the
lock floor.

The spillway consisted of rock filling, built
up gradually, as the hydraulic fill in the core
of the dam was increased in height. The
surplus water from the fill, passed over this
spillway, and was carried off in an artificial
channel, finally wasting into the Rio Grande.
It is supposed that a small stream of water,
which had been percolating through the rock
of the spillway, and the consequent disin-
tegration of the underlaying material from
this cause, combined with the constantly
increasing back pressure created by the mud
and water in the fill, had weakened the under-
laying material, and finally forced out the
bottom.

In the rush of silt and water, large rock
boulders forming the spillway were carried
away and distributed over the territory
immediately below. One of these became
lodged in the regular channel of the stream,
thereby augmenting the overflow in the
direction of the lock. No attempt was made
to stop the outlet, as it would have been
impossible to do so until the three or four
feet of silt and water over the solid portion
of the dam fill had run off to a depth that
could be controlled by sand bags. In this way
the flow was stopped after the expiration of
about an hour and one-half.

The greater part of the silt and water

{Continued.)



entered the upper lock at the extreme north
end, where a section of the bank had caved
in. The cave-in, however, involved no great
damage, as it would have been necessary to
excavate the bank at this point later, in order
to provide space for the wing walls. In its
course to the lock, the flood encountered
numerous obstacles, such as timbers, mach-
inery parts, tracks, etc., thereby diverting a
part of the flow, which ran along the tracks
extending parallel with the west bank, leaving
them completely covered in places with a
deposit of slime. At low points along the
bank, the material found its way into the
lock, and while the flood was at its height,
three points resembled small waterfalls.

In the lock chamber the slime and water
rose three feet over the finished floor. The
flooded conditions extended into the lower
lock, and partially submerged two of the
steam shovels at work there. A portable
concrete mixer, situated in the west chamber,
was involved, and a number of drills were
forced to suspend work.

An 18-inch, motor-driven, centrifugal
pump, with a capacity of 10,000 gallons a
minute, originally designed for use as a relay
pump in making the hydraulic fill of the west
dam, was installed, together with its pipe
connections, and on Friday evening, May 26,
began emptying the locks, pumping the slime
and water back into the core of the dam.
When the water was lowered sufficiently, the
work of sluicing the deposits of slime toward
the sump was begun, and continued until the
chambers were wholly cleared. This work
was practically finished by Wednesday,
May 31.

Practically none of the compacted filling
of the dam was lost; the overflow consisted
of the water and slime, which stood, as stated,
three or four feet over the filling. The slime
was pumped back into the dam, because it
was the quickest and most economical way
of freeing the lock, and most of it passed
over the repaired spillway. The loss is con-
fined principally to the delay in concrete
construction and excavation, and to the
expense of repairing the break, and clearing
the lock of mud and water. The lock walls
were in no way injured, and the total loss will
probably not exceed $8,000. With the excep-
tion of Saturday, May 27, when the con-
struction plant was shut down on account of
the clogging of the circulating water tunnel
at the power house, concrete operations, in
part, have been continued uninterruptedly.

The spillway has been rebuilt, and a well-
braced, firmly embedded wooden flume, with
inside dimensions of three feet, for regulating
the flow, has been constructed.



The Cruces Anchors.

A cable from the Secretary of War to the
Chairman and Chief Engineer, dated May
21, reads: "There is a rumor that it is con-
templated removing Spanish anchors from
Isthmus to West Point. The President
directs that this be not done."

These anchors, which were described in
The Canal Record of April 26, 1911, were
recently placed on a raft for transportation
down the Chagres River. The raft broke
loose from its moorings, and floated down
stream until it became entangled in the



branches of an overhanging tree near the
Panama railroad gravel bed at Gamboa.
Shortly afterward, a floating log collided with
the raft, causing it to break in two, and allow-
ing the anchors to sink to the bottom of the
river. They were pulled out a few days ago
by a Panama railroad locomotive, and are



now at Mount Hope storehouse pending final
disposition.

The Colon Humane Society has donated
the sum of S100 to be distributed among
needy cases in Colon or Cristobal, through
Mr. William Bennyhoff, who had charge of
the Red Cross camp in Colon.



CONCRETE WORK IN THE LOCKS.
