NOTES OF PROGRESS.



Fuel Oil.

The Union Oil Company delivered 74,929
barrels of fuel oil to the Commission in May,
the largest monthly delivery yet made. This
amount, however, is only a little in excess
of the February deliveries, which amounted
to 72,939 barrels, the greatest amount
pumped into the Commission tanks in any
one month up to that time. The point of
greatest increase in the oil takings for May
was Gatun, where the deliveries amounted
to over 18,000 barrels.

Three tank vessels are now engaged in
bringing fuel oil to the Isthmus from the
California fields, the Pectan, of 62,000 barrels
capacity, and the Oberon and Trinculo, each
of 45,000 barrels capacity. Two cargoes are
received, on an average, each month. Most
of the oil is delivered to the tank steamers
from the company's storage tanks at Port
Harford , but a small quantity has been shipped
from Oleum, another of the company's oil
ports.

The oil company has removed a part of
its transisthmian pipe line to the Panama
railroad relocation, and the remainder will be
transferred as soon as the railroad work is
far enough along. At Caimito the pipe line
crosses over to a point on the present oper-
ated road, near Barbacoas bridge, a distance
of about 7,000 feet. Another crossover is
made from the old and new lines of railroad
near the Miraflores power house, the relaid
oil line following the railroad relocation from
a point south of the tunnel to Paraiso Junc-
tion. The company is using some of its old
pipe in this work, but much of the material
i» new.



Fire Protection Measures.

A 1 0-inch pipe has been laid from the 20-inch
Rio Grande main to the high pressure reser-
voir on Ancon hill. It is intended for use in
case of fire in Ancon, or in the city of Panama,
when there is an unusual demand on the
water supply in the reservoir.

Upon recommendation of the Chief of the
Canal Zone Fire Department and the Super-



intendent of Public Works, approved by the
Chairman and Chief Engineer, a chart will
be prepared in the drafting office of the Pacific
Division for the use of the Panama authori-
ties, which will show the water system of the
city of Panama in colors, together with the
number of hose connections which may be
made in the various districts of the city on
the various mains. In addition, the location
of all hydrants will be indicated, in order that
the Panama firemen may be able to make
proper connections in time of fire.



Concrete Ditching.

Permanent concrete drains are being laid
along the beds of small ravines and gullies
at Empire, which, in the rainy season, serve
to carry off storm water. A total of about
9,000 feet of concrete drainage ditch will be
constructed, the work involving excavating
and straightening ~rhe natural bed of the
watercourses to established lines and grades,
the building of suitable culverts where roads
cross them, and placing concrete in the drains.
This work is confined to the section in which
the American quarters are situated, and is a
sanitary measure, as it will obviate the neces-
sity of removing obstructions which are con-
stantly washing into the ditches, including
dirt from cave-ins, and, in addition, will
reduce the amount of grass cutting to be
done. Similar ditches have been constructed
at Las Cascadas, and a system of permanent
drains will probably be installed at Gatun
during the next dry season.



Erosion of Slopes of Culebra Cut.

Arrangements have been made to sow
various kinds of grass seeds on the slopes of
Culebra Cut, with a view to reducing ero-
sion. The seed has arrived and will be planted
under the direction of Mr. H. Pittier, a
botanist from the Smithsonian Institution.



Canal Zone Road Building.

The concrete wagon bridge over the Man-
dingo River, near Bas Obispo, was completed
and thrown open to traffic shortly after June 1.
This terminates construction work, as far as
has been planned on the wagon road, extend-
ing north and south through the Canal Zone,
from Panama to Gorgona, a distance of 19.7
miles. The highway lies to the east of and
parallels the Panama railroad from Panama
to Pedro Miguel. Here, it crosses to the west
side of the railroad relocation, and, near Pa-
raiso Junction, crosses over again to the east
side. It extends back of Gold Hill, and ap-
proaches the east bank of the Cut between
Culebra and Empire, where slides have re-
cently encroached on the right-of-way. From
Empire to Gorgona, the road lies to the west
of and follows the double track line of the
Panama railroad. With the exception of a
few hundred yards at Pedro Miguel, the road
is above the proposed summit level of the
water in the Gatunand Miraflores lake regions.



No extension of this road to bridge the gap
between Gorgona and Gatun is at present
contemplated. The widths and lengths of
the various sections of the road are, as
follows:

The Marine Corps at Camp Elliott is
engaged in building a road to connect the
camp with the main highway. It begins at
the railroad station at Bas Obispo, crosses
the Mandingo River on a bridge, supported
by 60-pound French and 70-pound American
iron rail and joins the Zone road a short dis-
tance away. The labor and $150 worth of
material are furnished by the Marine Corps,
and material to the value of not to exceed
$200 is to be paid for out of Canal Zone
funds.

The new Empire-Chorrera road has been
graded for a distance of about a mile and
one-half out of Empire. The heaviest con-
struction on the entire route is probably at
the Empire end, where the roadbed has been
excavated from the side of a steep hill to get
over the ridge. In surmounting this ridge,
the original plans provided for a six per cent
grade, but to secure this grade required the
building of 4,500 feet additional roadbed.
It was therefore determined to shorten the
route this much, the higher line adopted in-
creasing the grade only two per cent. The
old Chorrera trail enters Empire directly
west of the town; the new road joins one of
the streets of the settlement further to the
south, and nearer the railroad. In excavating
the roadbed out of the hillside, a thin layer
formation of loose trap rock was encountered,
requiring very little breaking up, which is
being used advantageously in making the
outside embankment fill on the steep hill
slope, and in a rubble fill in sections where the
road is over clayey ground. The method
employed in making the rubble fill is to re-
move the earth from the roadbed, after the
grading has been done for a width of 16 feet,
the excavation thus formed being filled in on
the sides to a depth of 10 inches, raised toward
the center to form a 6-inch crown, with large
pieces of rock. The material is transported
to the point desired in Decauville cars, and
the rubble fill will be continued until the road
is extended too far from the rock supply.

The new road follows the high, well drained
land of the ridges, rather than the route of the
old trail, which, for much of its distance, ex-
tends over low land, boggy, and at times al-

most impassable in the rainy season. Only
onestream of importance is to be crossed, and,
with the possible exception of this, the Man-
dingo River, no bridges will be required,
although there are many culverts to be built.
A stockade, constructed from native mate-
rials, such as thatch and cane, and surrounded
by a barb wire fence, will be located at the
Mandingo River crossing about midway be-
tween the Zone boundary line and Empire,
in which the convicts employed in building
the road will be housed. A survey is pro-
posed for a branch road to Arraijan, and, in
case it is decided to build it, the stockade will
be useful, as the road will join the main line
nearby.
