From the primary filter the water passes through Venturi meters,
one for each bed, whieh record the rate of filtration. The water is
then run through a secondary aeration l)ox and a secondary filter.
The construction of these is the same as in the primary set. except
tha.t there is only one filter bed. The primary filtration effectually
eliminates the organic matter, and the secondary filtration the objec-
tionable mineral matter (iron and manganese). The daily average
of the primary filters was 2,540,233 gallons for the yeixv ending May
1, 1919. The beds were run 18 days on the average betvreen clean-
ings, but the time varied wath tlie season of the year from 9 to 51
days. The secondary filter was run at a rate about four times as
high and with a longer interval between cleanings.
The water is distributed by gravity through 49 miles of main
l.'i])e to 266 hydrants and 2,874 house taj^s. Tlie domestic consump-
tion is about 130 gallons per capita per day, but this is increased by
the consumption in factories, hotels, and other establishments to
about 190 gallons a day. This consumption is excessive, and the

AREA, POPTJLATIOX, AND INDUSTRIES.
Eiclgefield, a town typical of the western highlands of Connecticut.
is near the middle of the west bonndary of Fairfield County. Dan-
bury adjoins it on the north and Norwaik is 15 miles south on Long-
Island Sound. To the west is part of Westchester County, N". Y.
The town has an area of 35^ square miles. There are several exten-
sive stretches of woodland and many small wood lots. These woods
are uniformly distributed over the town on the hills and steeper
slopes and aggregate 14 square miles or 40 per cent of the total
area. The valleys are for the most part cleared.
Ridgefield was incorporated in 1709, and in 1901 the village was
made a borough. There have been no additions to or cessions of the
original territory. In 1910 the population was 3,118, an increase of
492 over the 1900 population. The density of population averages
88 to the square mile. The follovring table shows the population at
each census and the i>er cent change in the preceding interval :
