available as a fertilizer.
There were already in operation, Mr..
Potter said, filter beds. such as are pro-
posed for this city. in Plain6eld II. j..
and IN Berlin. AT tho former point the
beds are directly between two towns. The
man who is in charge of the filters lives
on the premises, and water procured from
wells dug directly beneath the beds is
used by his family. every member Of which

city named wheat and other crops are
grown on the beds 1t had been proven in
these cases that there was absolutely no

the future. at which this city will es-

consequences. The idea was. the speaker
said to place the beds in general di-
recton from the city, as indicated by the
prevailing winds, hut even with the wind
blowing off the beds no odor was discern
able at a distance of 100 feet.

pleted plans for a system of sewers to cover
the entire city, and would, he thought, be
successful in using all of those now in
use.
The pumping station. the speaker went
on to say, had been planned for use as an
electric light power house as we'll. II the
ideas agreed on were carried out the cost
OF lighting the city would not only be re-
duced from 30 to 80 per cent, but 500 lights
would be furnished, thus making II pos
slble 10 place one at every second corner
in the business portion and at every sec
ond or third corner elsewhere. With this
equipment the city would be as well off in
this respect as any he knew OF.
Mr. Potter having announced that he
would be glad 10 answer questions, Mr.
Raphael asked him IL the present scheme
was not mainly for new system OF sew
craze. the matter of lights being somewhat
incidental Ho answered in the affrma-
tive, whereupon he quericd as to the com
paratlve cost, Mr.. Potter stating in reply
that about two-thrds would he for the
sewerage plant and the remainder for the
lights. Mr.. Potter explained also that,
whole the present plans might call for
three boilers, for instance, and II was de-
cided not to build the light plant, only two
boilers would be put in.
BY way of making the matter still
clearer Chairman Dickson stated that the
plans for the engines of the two plants
were entirely separate and distinct The
idea was to economlze by having the two
