LOCATION.
me sewers are located generally about seven feet
from the center of the street on oneside the other
as determined generally by the location of the gas
pipes Where there are no water pipes the sewers
are located in the center of the street. This distance
was found to be none too much as the water pipes
were laid without regard to alignment and ap-
peared IN our trenches on Main South Institute and
Manalapan avenues. This location will undoubted-
~ give rise to complaint when house connections
are made: II will throw unnecessary cost on the
and will, in many cases, completely blockade the
whole street while connections are being made
me water pipes were already laid, and it was not
the same trench. The course followed was the best
that could be done under the circumstances.

ACCESSORIES.
Manhoes are placed at all functions and on the
larger sizes OF pipe at all changes of grade These
are brick chambers 5 by feet, and have 8 inch
walls. The brick work is brought to a circle 08
inches in diameter and is capped with heavy cast
iron manhole head. The outside of the brick work
is pastered to depth of 3 feet, and there are no
can act.
The inspections are branches of the size of the
sewer and are extended to within 10 inches of the
surface OF the street. They covered by cast
iron head which is placed inches below the sur
lace OF the street. Arranged in this manner they
are less liable to be tampered with and at the same
time are easily accessible They are placed on the
q ana inch sewers from 200 to 300 feet apart ac-
cording to local conditions
The hand holes are branches set In the same
manner as the inspections, but are not extended to
the surface. The open ends capped and cemented.

such occur. they are placed about midway be-
tween the inspections.
At the head of each line of sewer there is an auto
matte flush tank. Thisis brick chamber plastered
INSIDE and out and provided with head similar to
tne manholes. The tank has capacity of about
100 gallons, and is fitted with inch Rhodes VIII
hams slphon. Thetank is connected with the water
main, and the supply be regulated SO that twill
discharge once day oftener if desired. The si-
phon has no moving parts and is automatic in its
action. Whenever the tank llsup it discharges its
contents in about seconds and this rush of water
moves along any matter that may have tendency
to stand especially in the upper ends of the lines
The flush tank has been aptly called The life of

branches are set in the line of the sewer for
every house and for every vacant lot. These, as

be carefully preserved.
. GRADE.
The sewers are all given a grade sufficient with
the aid OF lush tanks to maintain cleansing We
loelty. The minimum grade established for the va
r1ous sizes is as follows: IN 0.4 per 1OO s in
O24 per 100; 10 in. 0.24 per 100; 12 in. O. "a per
100; and Is in. o 2 per 100.
LAND DRAINAGE.
Ihree inch land tiles laid In the ditch at the
side OF the sewers wherever it was thought ground
water was troublesome. They were laid in Main
street from Institute to South; ThrockmoTton from
Main to South Mclean, from Main to South South,
from Mechanic to Elm. and South and Mechanic
from Main to Hudson. These have very materially
improved the condition of the streets this spring
We are told the tile in Throckmorton street is run
ming nearly one-half full.
