Suction Dredging Near Mindl.
A trestle about 6,500 feet long has been com-
pleted at Mindi, parallel with and east of the
Panama railroad, and it is now being filled



with spoil from the excavation at Mindi and
the locks. This fill will make a dike, behind
which the suction dredge at work in the Canal
channel between Mindi and Gatun Locks will
pump about 4,000,000 cubic yards of material.
The dredge Sandpiper is already excavating
in this section, depositing its spoil on the
flats between the dike which parallels the
Canal in this place, and the Panama railroad.
The pumping of the spoil back of the new
dike will begin about March 1.



Gatun Filtration Plant.

The laying of concrete for the filter plant
at Gatun has been begun, and the amount
required will be about 1,200 cubic yards.
The work includes the construction of a sedi-
mentation basin about 75 feet square, of a
filter house three stories high, and a clear
water basin, with a capacity of about 225,000
gallons. The filter house will contain four
rapid gravity sand filters on the first floor, an
operating gallery on the second floor, and a
storage room for materials on the third floor.



Cement Deliveries.
Commencing with the sailing of the cement
ship Cristobal from New York about March 3,
daily deliveries of cement to the Pacific Divi-
sion will be reduced 800 barrels and deliveries
to the Atlantic Division will be increased 500
barrels. Under the new arrangement, the
Pacific Division will receive 2,700 barrels, and
the Atlantic Division 3.500 barrels of cement
per day. Five hundred barrels of the con-
signment to the Atlantic Division will be in
bags. The deliveries to both divisions, begin-
ning with the sailing of the Cristobal, will
total 6,200 barrels per day. as compared with
6,500 barrels per day at the present time.
Since January 19, 1911, the Pacific Division
has been receiving on an average 4.2S1 bar-
rels of cement daily and a considerable
stock has been accumulated. On this ac-
count, in addition to serving the concrete
mixing plants, and in order to ship empty
cement bags to Colon, the division has
been compelled to hold in service from
40 to 45 box cars. The matter of box car
detention was recently made the subject of
an investigation by a committee, consisting of
Mr. S. B. Williamson, chairman; Messrs.
W. J. Holmes and A. K. Stone, members,
and the following recommendations were sub-
mitted, all of which have been approved by
the Acting Chairman and Chief Engineer:

1. That as the detention of cars in the
Pacific Division is primarily due to the irregu-
lar sailings of chartered cement steamers, thus
causing a congestion in the shipments, the
dates of their arrival be regulated, so that
the Panama Railroad Company ship daily to
the Pacific Division the approximate amount
agreed upon.

2. That the Pacific Division be allowed to
ship cars containing empty cement bags as
soon as loaded, so that they may be stored in

the Cristobal yard where there is more track
room, and where, in cases of emergency, they
can be unloaded on the docks to await the
sailing of the Ancon or Cristobal. Hitherto,
the Pacific Division has been required to hold
these cars until the day previous to the sailing
of one of these ships.

3. In order to provide against possible
irregular deliveries in future, it was recom-
mended that the Pacific Division increase
its unloading forces temporarily, and that
sheds, capable of holding one or two cars of
cement, be erected at such of its mixing plants
as are reasonably permanent, so that when a
car shortage arises, these sheds may be utilized
for supply purposes.

Canal Zone School Notes.

Two additional teachers have been engaged
for the Canal Zone white schools. One has
charge of the fourth grade, and one-half of the
fifth, at the Ancon school; and the other, the
third grade, and one-half of the fourth, at the
Cristobal school. The corps of teachers at
the four largest schools now number, as fol-
lows: Gatun, 8; Ancon, 7; Empire, 6; Cris-
tobal, 6. The total teaching force in the
Canal Zone schools at present consists of 42
white, and 25 colored teachers. This is an
increase over the last school year of six white,
and four colored teachers. The enrollment
also shows an increase. In January, 1911,
it was: White, 1,048; colored, 1,209, a total
of 2,257. In January 1910,, it was: White,
819; colored, 1,086; a total of 1,905. The
January, 1911, enrollment shows an increase
in the number of white scholars over the same
month in 1910 of 229, and in the number of
colored scholars of 123, a total of 352.

During the present school year, it is prob-
able that steps will be taken looking to the
establishnemt of suitable schools in the more
important native communities in the Canal
Zone. There are six or seven of these settle-
ments, such as Majagual, situated on the trail
from Mount Hope to Porto Bello; Cucaracha,
near Culebra. and Las Sabanas, for which no
school facilities have as yet been provided.
The preliminary efforts will be confined to
ascertaining, through the assistance of the
police and revenue departments, the number
of children of school age in each of these com-
munities, and the amount of taxes paid. The
places will then be visited by the Superintend-
ent of Schools, or his representative, with a



view of procuring information as to the actual
requirements, including the necessary build-
ings, etc.

The school gardens for colored pupils,
planted in 1910 at Balboa, Culebra, and
Empire, have been continued. The one at
Empire is especially prosperous, and, it is
expected that $600, or more, in revenue will
be derived from the sale of produce raised in



it. The soil in the Culebra garden has not
been brought to the same state of fertility as
in the Empire garden, and it will be necessary
to work and fertilize it for one or two more
seasons before it can be made fully productive.
At Balboa, the colored pupils are nearly all too
small to work the garden successfully on their
own account, and outside help, therefore, has
had to be procured to carry it on.



CONCRETE WORK IN THE LOCKS.



GATUN LOCKS.



Over 54 per cent of the concrete for the system of three twin locks at Gatun has been laid,
the exact amount in place at the close of work on February 18, being l,125,792i cubic yards,
out of a total of 2,085,000.

A statement of the amount of concrete placed in the locks each day for the week ending
February 18, and of the total, follows; and a similar statement for the work in the spillway of
Gatun Dam is published elsewhere in this issue. The construction plant works 12 hours daily,
and the auxiliary plant 9 hours.
