NOTES OF PROGRESS.



Testing Stoney Gate Valves.

Tests of the Stoney gate valves that will
control the flow of water through the culverts
of the locks will be made at Gatun. Two
concrete piers have been erected on the
floor of the west chamber of the upper locks
on which the valves will be erected in hori-
zontal position for the first four tests. The
piers are about six feet high permitting free
access for the inspection of the roller trains.
The gates are of steel and are 10 feet 8 inches
wide by 18 feet 10 inches high, made to close
a hole 8 by 18 feet. The points to be deter-
mined by the first four tests are:

(1) The friction developed by the roller
trains when the valve is moved under a super-
imposed load equivalent to the water pressure
against the valve under operating conditions.

(2) The deflection of the valves under loads
equivalent to operating pressures and the
effect of the deflection upon the rollers to
determine whether it will be necessary to
provide rocker bearings on ends of valves.

(3) The effect of an eccentric pull on the gates
to simulate the conditions if the valve stem
is not attached to the gate on the axis through
the center of gravity. (4) The effect of
wear on the rollers and roller train tracks for
continuous operation under a working load.

Points 1 to 4 will be determined by assem-
bling the valve and roller trains in a horizontal
position and loading the valve with pig iron or
rails in increasing amounts to equal the pres-
sure due to varying water heads up to 60
feet. A wire rope run through each end of
the gates through snatch blocks to a hoisting
engine will permit of the valve being operated
at will. After points Nos. 1, 2 and 3 are
determined the valve will be moved back-
ward and forward through the full range of
36 feet at the rate of 10 feet per second for
several days, the valve to be loaded with 270
tons, the equivalent of a 60-foot water head
on a surface 8 by 18 feet.

Three other tests will be made to determine:
(5) The efficacy of the sealing devices, par-
ticularly the spring side seals, under water
pressure, and the water tightness of the



uncaulked skin plates and rivets. (6) The
effect on the spring side seals when gate is
operated. (7) The initial force required to
break the water seals and open the valves
about one foot. In test No. 5 it is proposed
to install the two sets of valves in the two
upper valve chambers in the center wall cul-
vert and to fill the culvert between the valves
with water and observe the leakage under
varying heads. After the valves have been
installed, and prior to filling the culvert with
water, point 6 can be determined by raising
and lowering the valve a few times. Test 7
will be deferred until the operating machinery
has been installed.



Excavation in Central Division.

On September 23rd, 49 shovels in the Cen-
tral Division excavated 68,878 cubic yards of
rock and earth in a working day of eight hours,
an average per shovel of 1 ,406 cubic yards for
the day. During this time the shovels were
under steam 392 hours and were actually at
work 276 hours and 20 minutes, and waiting
for cars 83 hours and 45 minutes, the rest of
the time being lost in mining, cleaning track,
repairing shovels, cleaning dippers, etc. The
number of shovels working and the amount
of material excavated in the different con-
struction districts on this date were as fol-
lows:

Shorets Cu. Yds.

Empire construction district 20 26.548

Culebra construction district 18 28.918

Chagres construction district 9 11,100

Pedro Miguel construction district. . 2 2,312

This material was loaded on 2,494 Lidger-
wood flats, 326 large Western and Oliver
dumpcars.and 1,595 small Western and Oliver
dump cars.

The amount of material disposed of at the

principal dumps on this day was as follows:

Cu. Yds.

Tabernilla 7,980

P. R. R. relocation 9.550

Miraflores 12,540

Balboa 16.530

Gatun 6,816

The remainder of the material was mostly
disposed of in small dumps bordering the
Chagres River.

On September 17th, 21 shovels in the Empire
construction district of the Central Division
excavated 26,611 cubic yards, principally
rock, in the working day of eight hours, an
average per shovel of 1,267 cubic yards.
During this period, the shovels were under
steam 168 hours and were actually at work
129 hours and 15 minutes, and waiting for
cars 18 hours. The other delays were due
to mining, cleaning track, repairing shovel,
moving back, etc.

Feeding Calfalfa at the Corrals.
A shipment of nine tons of calfalfa for feed-
ing in the Commission corrals at Ancon and
Culebra was received from San Francisco on
the steamer City of Para, which arrived at the
port of Balboa on September 18. Calfalfa
is a meal made of finely ground alfalfa and is



used as a feed for horses and cattle. A trial
shipment was received at the Ancon corral
some time ago and gave satisfactory results.
It is exceedingly nutritive, and is fed to the
animals in the corral by wetting and mixing
it with the regular feed of oats. Its cost is
about $19 per ton.



Boiler Efficiency With OU As Fuel.

Tests have been made recently at the Las
Cascadas air compressor plant and at the
Mount Hope pumping station to determine
the economy and efficiency of the boilers,
with California crude oil as fuel. These
tests are similar to those made at all the large
boiler plants in the Canal Zone, a summary of
which was published in The Canal Record
of June 8, 1910.

At Las Cascadas, the test was made on six
return fire-tube boilers, and consisted of two
trials of 7 '/i and 9 hours, respectively. The
first trial was made while the plant was oper-
ating under normal running conditions, while
during the second, an attempt was made to
increase the economy and efficiency by de-
creasing the amount of air supplied to the
furnace for combustion, closer regulation of
the oil and steam used by the burners, and by
operating the boilers at their full rated horse-
power. The second trial showed an economi-
cal adjustment of the burners (two to each
boiler), which was verified by the high evapo-
ration of water per pound of combustible,
and very little improvement could therefore
be made in this respect. The increase in
economy was obtained by decreasing the
amount of air supplied to the furnace for
combustion, by closing the ash pit doors and
dampers, and by operating the feed water
pump at a constant speed, keeping about one
and one-half gages of water in the boilers
throughout the test. Some results of the
test are as follows:

At Mount Hope the test was made on one
locomotive type boiler, the first trial being to
determine the economy and efficiency under
normal running conditions. A comparative
trial was then made for the same length of
time (16 hours), to see if an increase in econ-
omy could be obtained by decreasing the
amount of air supplied to the furnace for
combustion, carrying a boiler pressure of
about 80 pounds gage, IV2 gages of water,
and by closer regulation of the oil and steam
used by the oil burners. The results of the

second test show that a considerable increase
over the first test, both in efficiency and econ-
omy, was obtained, principally by decreasing
the supply of air to the furnace, close regula-
tion of the oil burners, and carrying a higher

Building Improvements.

The addition to the Empire schoolbuilding
was begun on Friday, September 23, and the
work will be advanced as rapidly as possible.
The improvements will not be completed
prior to the opening of school on October 3,
but the plans for beginning school work on
that date will be carried out. It is proposed
to use the old part while building operations
are going on.

The work of converting building No. 2 at
Miraflores, formerly a French labor barrack,
34 by 50 feet in size, into a commissary build-
ing is in progress. It will be ready for occu-
pancy in about three weeks.

The construction of an extension to the
car repair shed at Pedro Miguel was begun
this week. It will be 286 feet long by 36 feet
wide.

Lock Building in Pacific Section.

A new record was established in the locks
of the Pacific Division last week, when 13,390
cubic yards were laid at Pedro Miguel and
5,048 cubic yards at Miraflores, a total of
18,438.

The auxiliary plant at Miraflores consists
of eight concrete mixers, two 2-cubic yard,
five '/2-cubic yard, three of which were recently
received from the States, and one Ms-cubic
yard. Two of the Va-yard mixers are now in the
shop undergoing repairs. A part of the out-
put of the 2-cubic yard mixers is used in the
center wall construction and is carried into
the lock in a Western dump car, eight yards
at a time. The remainder of the concrete
from these mixers is carried in buckets to where
the east berm crane can dump it into the east
side wall. Two of the small auxiliary mixers
are situated near the east side of the forebay,
close enough to the edge of the lock to permit
the output being sent down a chute into the
head wall. As soon as the work at that point
is completed they will be removed to a similar
position near the west side of the forebay to
build the head wall of the west chamber. The
other small mixers are employed in extending
the floor and culvert section in the east
chamber.

The east head wall is nearly finished; a
section of the east side wall is ready for the
culvert forms, and a piece of the batter or
foundation section of the center wall is in
place. Before operations on the west side
wall can be begun, a sloping^ledge of rock and



earth extending along the west chamber will
have to be removed, and steam shovels will
be set at this work some time during the coming
month. This will necessitate taking up the
construction track that now extends along
this ledge down into the lock, but a new track
into the lock directly out of the north forebay,
will be laid.

The record of concrete laid at the Miraflores
Locks for each of the six 8-hour working days
in the week ending September 24, and the
total to that date inclusive, follows:

The construction plant was shut down on
September 24, from 7.18 to 9.44 a. m., and the
auxiliary plant from 7.05 to 9.45 a. m., on
account of a lack of water due to a break in
the main.



No more assignments will be made to the
bachelor quarters in the Tivoli section, Ancon,
known as house No. 70, in view of the pro-
posed conversion of the building into family
quarters.



New Line Between San Francisco and Balboa, and
New Service of Old Line.

A new line of steamers will begin a fort-
nightly service between San Francisco and
Balboa (Panama), with San Pedro (Los Ange-
les) as a port of call, on October 1, when the
first vessel will sail from San Francisco. This
is due at Balboa on October 15. The ships
will be operated by the California and Atlan-
tic Steamship Company, Bates and Chese-
brough' agents, San Francisco.

The Panama Railroad Company has grant-
ed to the new line regular through billing
privileges on coastwise traffic on the same
terms and conditions as those held by the Paci-
fic Mail Steamship Company. The principal
concessions thus made are 70 per cent of the
through freight rate on coastwise traffic, and
the waiving of wharfage, craneage, lighterage,
and basin charges at Balboa on such, traffic.
Coal will be sold the ships at Balboa at the
cost price delivered in Colon, plus 42.25 freight
charge per ton for haulage across the Isthmus.

The steamships chartered for the Pacific
service are the Mackinaw, George W. Fenwick,
and Stanley Dollar, all steel, single screw
steamers. The Mackinaw will be equipped
with cold storage space for 200 tons, with the
expectation that arrangements may be made
to supply California fruits and vegetables to
the Isthmian Canal Commission.

In order that the ships on the Pacific may
not have to depend entirely on the Panama
railroad ships for carrying freight from the
States to Colon, the steamer San Mateo has
been chartered by the new company to carry
freight from Philadelphia and New York to
Colon, and returning, to take and deliver
freight at New Orleans and Charleston. The
itinerary will take 45 days.

The Pacific Mail Steamship Company will
establish a direct freight service between San
Francisco and Balboa with sailings from both
ports every 15 days. The first ship in this
new service will leave San Francisco on Septem-
ber 30, and leave Balboa on October 23. The
present service, with calls in Central America
and Mexico, will be continued with ships
sailing every ten days.

An article outlining an improvement in
terminal facilities at Balboa was published in
The Canal Record of September 14. These
improvements will be hastened as much as
possible in order that the increased business
at Balboa may be handled expeditiously.
The remodeling of the steel pier and the in-
stallation on it of better cranes will be begun
at once, and the new cranes will be contracted
for in such time that they may be installed as
the work on the pier advances. Work on the
concrete dock that is to be constructed south
of the present sand dock will be pushed as
much as possible, but it is not likely that it
can be completed within nine months.
