at a level of from 4 to feet below
the level of the laterals. The points of
the mains are made with concrete. The
Joints of the laterals are of what is
known to the trade as stamford
Joints, which is simply a band or ar
tificial rubber. These joints through
out the II miles take in and draw into
the systems an immense quantity of
water, in this way assisting the sub
soil drainage, and while drawing in
this water every gallon thus drawn
takes with it small quantity of
sand amounting, by test made dur
ing this work, to from a teaspoonful
to tablespoonful to each bucket of
five gallons. To prove this fact, |

to 1900 buckets delivered each min

Again my theory is proved by the
fact that in the whole course of this
extensive cleaning of sewers, no

found to be even partially choked by
home deposits or closet matter. These

Of ground water; 1000 gallons are
emptied each minute, which gives 800
to 1900 teaspoonfuls each minute, or
5000 spooIfuls per hour. Whenever
this sand falls into running water it
is harmless, for it IL borne on to the

At the corner OF G and Cochran
avenue there has been created a per-
manent loss of flow, This was faulty
construction by the engineer. The
same thing exists to a smaller extent
at the corner of Cochran and Mans-
field. No good flow of water can pos.
sibly exist at either of these points,
and it is between thee two points that
all the trouble exists.
The only remedy is to keep the well
as low as possible, and for as many
hours per day as is consistent with
regard for economy; and in addition,
to keep two laborers steadily the year
round at work upon the system wher-
ever work may be needed. A new
hand-pump and hose should be pur-
chased and I would ask that $50 feet
of one inch rubber hose, which would
cost about $4,000 be added to the
cleaning plant,
With two laborers allowed me, and
say $4,000 worth of material, am sure
could keep the whole system always
in perfect condition.

Finally, I think l can congratulate
the council upon the condition of the
system. There are two serious errors

and the other at Cochran and Mans

quire work and though the effects may
be lessened, the intervening sections
will require constant attention.

boiler is in a crippled condition, for
the reason of defective f1ues. The cut

put in. The auxiliary engine and
pump is in place, but no covering has
been built for the engine. The cover
to the well is rotten. The original
boilers were put up in 1894 and ran
