IL has been suggested that the public may
have an exaggerated idea of the Importance
OF putting this reservoir into immediate SER

reservoir as soon as practicable, but the high
service has been well supplied for about
twenty years without it, and the chief present
value OF the reservoir is limited TO getting rid
of night pumping. Just "a much water will
be required with a reservoir as Is required
without IT, and the pressure will be just the
Ii Is not desirable to draw of the water
from the reservoir so as to expose the bottom
at this season of the year; because great
damage would be done IL frost should get
through the concrete flooring.
The great area of assured rock found to be
not properly covered when the reservoir first
failed. was believed by me to be too large for
practical treatment in this way, and Mr..
Francis of Lowell and Mr.. Church of New
York, who were then called In consultation,
were agreed in the opinion, in which con-

of the banks on the interior surfaces would be
effectual or economical.
But now the conditions are much changed
by the new layer of impervious material and
