Death of Col. J. R. Shaler.
Col. James R. Shaler, formerly General

Request for Special Trains.

As requests for permission to run Commis-
sion equipment over the main line of the Pan-
ama railroad are occasionally submitted to
the office of the Chairman in incomplete form
or too late for action, the following circular
is republished for the information of all con-
cerned:

Culebra, C. Z., October 9, 1909.
Circular No. 286:

Employes will hereafter be governed by the following
regulations in submitting requests for permission to run
Commission equipment over the main line of the Pana-
ma railroad:

Requests for permission to run Commission equipment
over the main line of the Panama railroad must be sub-
mitted in writing to the office of the Chairman at least
three days prior to the date on which the train is de-
sired. This is necessary in order to allow sufficient
time for forwarding the request to the Panama railroad
and receiving reply as to whether it is practicable to
grant the permission for the date specified.

Requests should state:

Whether permission has been secured for the use of
Commission equipment.

Whether a qualified crew will man the train.

The points between which the train is to be run.

Time of leaving and arriving at terminals, and inter-
mediate points at which train will stop, in order that
the despatcher of the Panama railroad may arrange
a schedule accordingly.

In all cases qualified crews must be used, and train
equipped with flags, markers, torpedoes and fusees.

Fatal Accident on Gatun Labor Train.

John J. Coit, a white American, was killed,
and a West Indian negro was seriously in-
jured in an accident to the Gatun-Culebra
labor train, near Mamei, on the morning of
September 21. About 200 feet from Bridge
47 on the main line of the Panama railroad,
engine No. 500, hauling the labor train, ran
into a cow. The locomotive left the track
and turned over on the south bound main
line track. The engineer, John J. Coit, was
killed instantly, and the negro fireman sus-
tained serious injuries. The south bound
track was clear by 8.45 o'clock in the fore-
noon.

John J. Coit was 35 years of age, a resi-
dent of Los Angeles, Cal., and had been on
the Isthmus since July, 1908. He was a
locomotive engineer in the employ of the
Atlantic Division, and his residence in the
Canal Zone was at Culebra. He was unmar-
ried. A sister, Mrs. C.J. Stanton, 418 Solano
avenue, Los Angeles, Cal., survives him.

Canal Zone Rifie Club.

The Canal Record:

All persons interested in military rifle
shooting and desirous of becoming members
of the Canal Zone Rifle Club, are requested
to correspond with the Secretary, Pedro
Miguel, C. Z. This club is affiliated with the
National Rifle Association of America and
purchases its arms and ammunition from the
Government. The club holds four shoots
annually for members to qualify as marksmen,
sharpshooters and experts, as provided for
under the rules and regulations of the National
Rifle Association. Lapel buttons are fur-
nished members by the association, showing
the class in which they qualify. An order for
arms and ammunition will be placed in the
near future, so send for an application blank
for membership as soon as possible.

H. L. Bridges, Secretary.

Masonic Temple in Colon.

The Panama Railroad Company has been
authorized to lease to Sojourners Lodge, No.
874, F. and A. M. of Colon, the lots in that
city bounded on the east by Bolivar street,
on the north by 11th street, and on the west by
Bottle alley, to be used as a site for a Masonic
temple. Tentative plans for the building
provide for a fireproof structure of concrete,
120 feet long, 90 feet wide, three stories high,
at a cost of about $50,000.

Culebra Cut construction trains, running
into the Cut north of the summit, began using
the incline at Whitehouse on September 16,
after several months during which the tracks
were not considered safe. A pocket of earth
and rock had given way in the incline and it
was necessary to dump hundreds of carloads
of rock before a stable roadbed could be pro-
cured.

THE CANAL RECORD

August, 1910, than in the corresponding
month of the previous year.

The total amount of material excavated
from the prism in the Culebra section of the
Central Division in August, 1910, was 1,377,-
714 cubic yards, being the highest record in
that section for the month of August, the
previous high record having been in August,
190S, when 1,173,800 cubic yards were re-
moved.

The total estimated amount of material to
be removed in the Central Division is 97,125,-
018 cubic yards, and up to September 1, 1910,
61,747,577 cubic yards had been removed,
leaving 35,377,441 cubic yards to be removed
in order to complete all excavation in the
Central Division. From these figures it will
be seen that 63.58 per cent of all excavation
in the Central Division had been completed
up to the close of the month of August, and
36.42 per cent remained unfinished. Con-
sidering the two sections which compose the
Central Division, the excavation completed
and that to be completed at the close of Au-
gust operations were as follows:

CULEBRA SECTION.

Cubic Yards.

Completed 51.826,590

To be completed 32,360.134

CHAGRES SECTION.

Completed 9,920,987

To be completed 3,017,307

From the above figures it will be seen that
the Culebra section, locally known as Culebra
Cut, was 61.57 per cent completed, with 38.43
per cent to be completed; the Chagres section
was 76.65 per cent completed, with 23.35 per
cent to be completed.

During the month the following quantities
of material were hauled from the Canal prism
and dumped in the embankment for the new
roadbed for the relocation of the Panama
railroad: 7,841 cubic yards in the vicinity of
Pedro Miguel; 10,392 cubic yards between
Caimito and Gamboa. The total at the close
of the month used for this purpose was 3,713,-
.268 cubic yards. During the month, 147,420
cubic yards of rock and earth from the Culebra
Cut were transported to Gatun for use in the
construction of the Dam, making the total
at the close of the month for this purpose
1,831,617 cubic yards.

The daily average number of laborers at
work on the whole division during the month
was 8,562, the average number of gold men
being 886.

PaciBc Division.
DISTRICT NO. 1 — LOCKS AND DAMS.

The total excavation during the month
amounted to 30,337 cubic yards. During

total amount in place at the end of the month
260,852 cubic yards, as previously reported;
2,360 cubic yards of dry filling were placed in
back fill, increasing the total to 15,943 cubic
yards. At Miraflores, 10,898 cubic yards of dry
filling were added to the toe; no hydraulic filling
was added to the core of the west dam, making
the total at the close of the month 536,089
cubic yards, and 138,587 cubic yards, respec-
tively. During the month, 6,355 cubic yards
of dry filling were placed in back fill, increas-
ing the total to 133,545 cubic yards.

The operation of the handling plant at
Pedro Miguel continued with few interrup-
tions during the month. The output from
the plant was increased 20 per cent. One
temporary mixer at the south end of the west



storage trestle, in the forebay, was installed,
and work was commenced on the temporary
mixing plant at the south end of the east
storage trestle.

August showed an increase of 9,800 cubic
yards over the output for July. The total
amount of concrete placed during the month
