THE CITY's WATER SUPPLY.
Col. EllIott's Report on the Conduit and
Reservoir.
WORK DONE DURING THE PAST MoNrH-ENGfN-
EERING OPERATIONS TO BE UNDERTAKEN-
THE CONDUIT RoAD-coNDIrIoN OF THE RES
ERvoIRs.

Gen. Casey, chief of engineers. has received
the report of Col George H. Elliot, corps of
engineers, in regard to engineering operations
on the Washington aqueduct for the month Of
May.
The report says the grounds around the
mouth Of the conduit at the Great Falls were
cleaned up, and the deposit Of mud in the
channel just above the mouth Of the conduit
was cleaned out.
THE CONDUIT.
On May the conduit from Great Falls to
the Dalecarlia reservoir was emptied and
about twenty-five square yards Of the
inside of the big conduit below the
north connection was plastered with
cement to diminish the leakage through the
masonry arch Of the by-conduit, which, as pre-
viously stated, is extremely poor and permits the
water in the reservoir and the by-conduitt to flow
from one to the other whenever the water is
lowered in ether through numberless assures.
The by conduit was temporarily under the De-
partment of the Interior during the late
civil war. On May 10 the conduit
was emptied from Great Falls to the distribu-
ting reservoir and a survey was made Of aQue-
duct tunnel No. and portions Of the Dalecar-
liza reservoir near the north connec-
the main drainage tunnel required in
the improvement of the reservoir un-
der the act Of March 8, 1898. At
the same time several OF the leaking assures
through the masonry Of the south connection,
which was constructed at the same time as the
big condoit, were plugged with white pine
wedges.
The Conduit road. where it passes down the
western slope of Dalecarlia hill, was graded,
ready for Macadam pavement, which, it is
proposed, to lay in July. The channel below
the spillwav at the Dalecarlia reservoir was
again cleared out.
The conduit road near the south connection
OF the Dalecarlia reservoir was repaired and the
loose stone on the road between culvert
"a and the Dalecarlia reservoir which
has recently been covered with a
coating of flint rock. was removed. This por
better condition than ever before, and Col.
Elliot says he regrets that the current
appropriation for the preservation and repair
of the Aqueduct is too small to enable him to
place more of the road in the same condition.
substantial fence was built along the
dangerous embankment at culvert No. n. The
cleaning out OF bitches on the sides of the Con-
duit road was continued and a length Of $50
feet of cutters was paved on the east side Of the
road near waste weir No. 8.
THE RESERVOIRS.
An iron railing was put up around the south
at the Dalecarlia reservoir for the
security Of the Waterman in execution
of his duties in icy weather. The
survey for project Of improvement of
Dalecarlia reservoir was carried on during the
month. and a small frame building for a shelter
Cor the surveying party was put up on top
of Dalecarlia Hill. over aqueduct
tunnel No. 4. A project for the expenditure of
the 900 appropriated by act of March 8. 1893,
for the improvement Of the Dalecarlia
receiving reservoir submitted
to the chief OF engineers and was
approved by him. The act provided that the
work should be done by contract or otherwise
as the Secretary Of War should determine and
he approved Col Elliott's request for authority
to carry it on by days labor.
THE MAINS, &C.
Pressures were taken May % on Capitol Hill as
follows: New Jersey avenue and b street north
east, s. pounds; LIST and B streets northeast.
221s pounds, and I'd and East Capitol streets
161S pounds. The amount Of water consumed
and wasted in twenty-four hours ending a: 7
a. M. May 8. was measured and found to be
IS. SOC. 453 gallons.
An Improvement was made in the waste gate
in the dam at waste weir No. 8. so that two
men can now easily operate the gate.
PROBABLE OPERATIONS.
During the month of June it is proposed to
build new fence around the Office yard;
further repair the telephone line; con-
tlnue the surveys at Dale Carlia reservation;
purchase the machinery required for the main
drainage tunnel and make the other necessary
