WILLIAM WIENER, A. NJ, Phi. B.
The judging the domestic or sanitary
governed by the following rules:-Should
a water contain over forty grains Of
solids, it is subject to suspicion. Five to
ten grains of chlorine in 100000 parts are
not to be considered an objection, and
only under certain conditions suspicious.
If the amount of albuminoid ammonia is
600 parts per million, in spite of much
free ammonia and chlorides. it is con-
sidered organically pure. Should the
albuminoid ammonia be less than .05 per
million, the water Is regarded as pure.
II albuminoid ammonia is over .O5, then
the free ammonia must enter into the
calculation. Should free ammonia be
present in considerable amount and al
buminoid ammonia over .05 per million,
the water must be considered as very sus-
picious. Nitrites, nitrates, phosphates
and chlorides, by their presence indicate
animal and vegetable contamination
Hardness is only of Importance when the
ratio of hardness to total solids is In the
proportion 12.
Judging the present water supply by
the above rules and several other circum-
stances, the water exceeds the usual lin
its of safety points In many respects, but
in its present state would prove source
of great danger only in time Of an epi-
demic of typhoid fever or cholera.
Though the water has a better appearance
than it did have during the summer, be-
cause there have been no excessive rain
storms to bring an unusual amount OF
floating matter into it to render it turbid,
nevertheless it is nearly as fruitful in
causing diarrh9a and bowel troubles as 10
was during the summer.

1t should be added to the report that the
water supplied to the city last week was
almost wholly taken from the Passaic.
Only one part Of one day, either sunday
or Monday, did any Pequannock water
flow into The reservoir at Bellevllle.
THE BOARD OF TRADE COMMITTEE.
Last night special committee OF the
Board of Trade made report on the re-
sults of visit TO the new reservoir and
the accessible points on the pipe line.
The committee consists or Elias Ward,
Harrison Van Duyne. James ,. Higbie,
CYRUS Peck and John Hlingworth.
Vent to Pompton on Wednesday morning
by the Greenwood Lake road and were
met at the station by one of Alexander
Gilland's teams from Pompton Plains.
The committee then drove up the Pequan-
mock valley, viewing the inlske reservoir
there to Oak Ridge where they
looked at the big dam and gazed at
the broad expanse of water and the
magnificent display OF water in the spill
Way which passes through the deep rock
cut to rejoin the Pequannock below the
dam and just above The public road. Then
they drove to Clinton Falls and inspected
the half filled reservoir there and looked
at the big dam which stretches across the
valley.
that the city should own the land on both
sides of both streams from the two oi4
reservoirs to the intake, and that proper
precautions against pollution can not be
maintained otherwise. They found tna5
the stories about dangerous leaks were
gross exaggerations. One important leak
exists at Oak Ridge, but IL is not In the
dam aud it is quite puzzle to the engln-
GERS but it does not threaten the destruc-
tion of the work. 1t sin the seemingly
solid masonry of the gate house deep
down in the cut and is vexatious because
it is almost inaccessible and will entail
an expense OF from 10000 to $4,000 to
oyernawl the walls and permanently close
the outlet. The other leaks below the
big dams are no more than might be ex-
pected in works of such magnitu de. They
are in the form of springs, The water hav-
ing fodn its way under the core of the
dam in places through natural assures in
the bed rock. the pressure OF the great
volume of water above being sufficient
to omen seams which could not be de-
tected until the reservoirs were ti}ed.
They are regarded as unimportant as
source of loss, however, ana it is said that
similar leakages have been found below
aver big reservoir in this country with
the exception of two.
