had been forwarded to the sovereign grand
lodge for the transfer of Canal Zone Lodge,
No. 3, from Culebra to Empire. There are
only a few members of this lodge living at
Culebra, and it is believed that the new
location will not only be more central, but
that the change will result in an increased
membership. Mr. Sisson, who has general
charge of Odd Fellow affairs on the Isthmus,
has just finished his fourth year as district
deputy grand sire.

GATUN LOCKS.

Crane excavation in the lower lock, and
shovel excavation for obtaining clay for back
fill, were continued. A total of 4,725 cubic
yards were removed by crane, and 8,067
cubic yards by shovel. On June 30, the total
excavation amounted to 5,869,271 cubic yards,
of which 5,029,334 cubic yards were removed
from the prism. The excavation in the locks
was 99.6 per cent completed, and the exca-
vation of the culvert trenches 90 per cent
completed.

Back fill — Backfilling behind the walls of
the upper and middle locks, and in the center
wall of the upper lock, was continued, and
back filling behind the walls of the lower lock
was commenced. The quantity placed during
June aggregated 52,013 cubic yards, in-
creasing the total to 543,576 cubic yards.
On June 30, the back filling was 33 45 per cent
completed.

Receiving and Issuing Material — The re-
ceipts of all material during the month
exceeded the consumption, excepc in the case
of sand, where the excess of consumption over
receipts amounted to 184 cubic yards.

Mixing and Placing Plants — Both plants,
and all portable mixers, were kept in satis-
factory operation during the month.

Power Plant and Pumps — The operation
of the power plant and pumps was satisfactory.

Iron and Steel Work — During the month
508.84 tons of fixed steel, 69.5 tons of re-
inforcing rails, and 5,705 feet of reinforcing
rods were placed.

Concrete Work — There was a decrease of
12,539 cubic yards in the amount of concrete
laid, as compared with the figures for the

GATUN DAM.

Construction during the month increased
the total fill, as determined by cross sections
of the material in place, by 660,004 cubic yards.

Cross section survey was completed of all
the material in place for the purpose of
determining the yardage lost by consolidation,
and the total yardage still remaining to be
placed to complete the Dam. This shows the
net yardage in place above the original ground
surface to be 14,293,034 cubic yards, a short-
age of 441,782 cubic yards from the amount
determined by the summation of the monthly
cross sections, which only cover the material
actually deposited during the month. This
shortage has been charged against hydraulic
fill in place, as it is probably nearly all due
to consolidation of same. The net amount
of material required to complete the Dam



to elevation plus 115, over and above that
now shown in place, is 5,089,156 cubic yards;
for the gross amount necessary to complete,
about 500,000 cubic yards should be added
to this to cover future consolidation.

Hydraulic fill — The dredges increased the
hydraulic fill by 432,008 cubic yards. Making
a reduction of 441,782 cubic yards chargeable
against consolidation, as shown by a complete
survey of the Dam, the total hydraulic fill in
place June 30 was 7,411,992 cubic yards.

Dry fill — Material received from the Cen-
tral Division, the Locks, Mindi, and steam
shovel No. 134, amounting to 227,996 cubic
yards, was placed on the north and south
toes of the Dam, east and west of the Spillway,
making the total dry fill in place 6,881,042
cubic yards.

GATUN SPILLWAY.

Excavation — In preparing foundations of
theSpillway dam, 115 cubic yards of rock were
removed by hand. On June 30, the total
spillway excavation amounted to 1,582,960
cubic yards.

Concrete — The work of placing concrete
was continued, the amount placed during
the month aggregating 4,830 cubic yards,
which increased the total to 143,746 cubic
yards. The concrete work for the Spillway
was 66.1 per cent completed.

HARBOR AND CHANNEL SECTION.

Excavation Below Sea Level at Mindi —
During the month, two steam shovels removed
9,659 cubic yards of earth, and 45,998 cubic
yards of rock from the Canal prism. In
addition, 3,500 cubic yards of earth were
sluiced by pumping plant.

Dredging from the Ocean to Mindi — Five
dredges removed 431,655 cubic yards of earth,
and 20,443 cubic yards of rock from the
Canal prism. In addition, dredge No. 86
placed 97,149 cubic yards of material in the
Colon fill. On June 30th. 40 feet of water
could be carried from zero to zero plus 2,200
feet; 35 feet to mile 3 plus 800 feet; 30 feet
to mile 3 plus 3,700 feet; 20 feet to mile 5
plus 2,438.9 feet, at the junction with the
French canal.

water, and 2,128 cubic yards in track fill.
The double track trestle was extended 592J
linear feet. On June 30, the trestle extended
5,365 feet from shore. The total amount of
rock dredged and dumped on the west break-
water to June 1, 1911, was 598, 709 cubic yards.
During the month, 20,443 cubic yards were
dredged and dumped, increasing the total to

NOMBRE DE DIOS.

During the month, 50 barges, containing
23,251 cubic yards of sand, were shipped to
Gatun.

MUNICIPAL ENGINEERING.

The reservoirs, water mains, sewers, roads,
and oil pipe lines were maintained and ex-
tended, as required, to facilitate construction
work. Work was continued on the Colon
municipal improvements.

Central Division.

During the month of June, the total amount
of material excavated in the Central Division
was 1,433,304 cubic yards, of which 140,605
cubic yards were classified as earth, and
1,292,699 cubic yards as rock. Of this quan-
tity, 1, 399.45S cubic yards were removed by
steam shovels, and 1,558 cubic yards by
bucket cranes. Contractors removed 29,856
cubic yards by sluicing, and 2.432 cubic yards
by hand. The total — 1,433,304 cubic yards —
consisted of primary excavation for the Canal
prism.

The daily average number of steam shovels
at work during the month was 40.92. and the
total number of shovel days was 1,064, as
compared with 38.62 shovels at work during
the month of May, with 1.004 shovel days.

For comparison with the work done by
steam shovels during the corresponding
month of the previous year, the following

The above table shows the average output
per shovel to be 7.08 per cent greater in June,
1911, 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 June, 1911—1,401,016
cubic yards — was the highest record in that
section for the month of June, the previous
high record for the month having been in
June, 1910, when 1,305,141 cubic yards were
removed.

Due to changes in the stability of the Canal
banks in the Culebra section, it has been
found necessary to add 2.571,690 cubic yards
to the original estimate for the completed
Canal making the revised total estimated
amount of material to be removed in the
Central Division, 99,696,708 cubic yards,
and up to July 1, 1911, 77 338,235 cubic
yards had been removed, leaving 22,358,473
cubic yards to be removed, in order to com-
plete all excavation in the Central Division.
From these figures, it will be seen that 77.57
per cent of all excavation in the Central
Division had been completed up to the close
of the month of June, and 22.43 per cent
remained uncompleted.

Considering the two sections which compose
the Central Division, the excavation com-
pleted, and that to be completed, at the close
of June operations, was, as follows:

CULEBRA SECTION. Cu. Yds.

Completed 65.514,865

To be completed 21,652,852



CHAGRES SECTION.

Completed 11,823,370

To be completed 705.621

From the above figures, it will be seen that
the Ci'lebra section, locally known as the
Culebra Cut, was 75.16 per cent completed,
with 24.84 per cent to be completed; the
Chagres section was 94.37 per cent com-
pleted, with 5.63 per cent to be completed.

During the month, no material was hauled
from the Canal prism for the embankment
for the roadbed of the relocated Panama
railroad, the total amount used for this pur-
pose remaining at 3,830,137 cubic yards.
The Central Division delivered at Gatun
223,657 cubic yards of rock and earth, for use
in the construction of the Dam, making the
total for this purpose at the end of June,
3,789,118 cubic yards.

The daily average number of laborers at
work on the whole division during the month
was 6,777, and the daily average number of

gold employes, 776.

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

Excavation — The total excavation during
the month amounted to 120,943 cubic yards.

Filling and Embankment — During June, no
additional dry filling was added to the prism

Miguel was increased by 18,871 cubic yards,
the total in place at the end of the month
amounting to 283,325 cubic yards.

At Miraflores, 28,315 cubic yards were
added to the dry fill in the toes, and 53,858
cubic yards to the hydraulic fill in the core
of the west dam, making the totals at the
end of the month 816,499 cubic yards, and
582,732 cubic yards, respectively. The back
fill was increased by 16,155 cubic yards, the
total aggregating 174,601 cubic yards at the
end of the month.
