The Cornish engines now in use at the

as, for instance cleansing the Augean

showed that where filters were used the
epiqemic was greatly minimized.

When the reading of the report came
to an end Mr.. Dear briefly enumerated
its strong points, and said that the city
could nor assume any more debt 1t
could not afford to double its indebted
ness for plant costing $4,000 600 when
good water could be mad by filtration
which would cost a. sixth of that sum-.

advocating pure supply and no filtered
sewage. Mr.. Myron Furst ended the des-
ultory talk by moving that the report be
received, and the Board should meet in
two weeks TO more fully discuss it.
No one then. he cogently said, could ac-
cuse the Board of snap action Mr.
Furst's suggestion was agreed to and
the meeting adjourned.
