from to-day it will be available. This is GER
tany as short d time &C can be allowed for the
construction Of works for the required supply,
wherever the source may be"
What sources Of supply available?"
"Ramapo. Housatonic and Long Island have
been discussed in preliminary reports. which
will be distributed soon. The Delaware River
Lake ontario and Lake Erie have been men
toned. Some private companies have also made
propositions OF furnishing water and others are
thought to be ready at any time"
UNABLE TO CLEAN THE HAMPSTEAD
STREAM.
How long have you been in charge Of the
water supply engineer"
Since jury Of 1894 when appointed by Com
missioner White"
What is the present condition Of the ponds
as compared with what they were at that time"
THE condition OF the ponds compares favor
ably with what they were three years ago. Great
Improvement can be shown in every one Of them.
We are always at work cleaning them. and have
cleaned them as far the appropriations FOR
that purpose go. and as Far as allowed by owner
ship or the permission Of landhoders. In some
cases the latter object to our entering their
our water supply is Hampstead. Ye- If is at the
same time our most important stream. There
the danger of pollution has been pointed out re-
peatedly. The situation is thoroughly we'll
known to us, and has been carefully studied.
and the remedy has been devised. An appro-
priation of $4,000 was asked for i'st January
to build the necessary works 10 protect that
stream and has been before the Board Of Alder
men. Commissioner Willis has more than
recommended the appropriation Of this amount
We shall either have to abandon the stream or
protect it by the works already planned"
THE REPORT FOR 1885
Engineer de varonas report for 1895 shows
that a series OF test wells has been driven from
the bottom Of the hill at Rdgewood reservoir to
the Forest Stream pumping station. Zach well
being carried to such depth II determine
beyond question the possibility Of securing
supply from that point. Easterly from Jameco

The water from the strata below tho blue clay

ADDITIONAL TEST WELLS TO BE SUNK.
II is evident that an important supply. which

lions above referred to- sinking additional test
wells I'm order TO determine, as far as practical
bic the character and nature Of this under
ground supply and the extent OF the tributary
area in each case. The results hitherto obtained
certainly warrant the fullest examinations.
Exneriments were made to determine the yield
~ four flowing wells at Jameco and the ex-
tent Of the underground supply. 1t was shown
that the average yield from one well alone was
ooo 600 gallons daily. The total yield was
2 ino On gallons daily when the four wells were
IN ooeration. The lowering OF the water in the
underground stratum was approximately five
feet when pumping l.00OOOO gallons daily. in
creasing to approximately ten feet when pump
ing to the full capacity Of 100000 gallons.
II should Doe stated in connection with this
work that the water in the test wells Is found
to rise and fall directly with the tide. making
