flush tanks, each containing 500 gal.
Ions of water, the valves Of which
are 90 set, as to produce discharge
periodically, say: once in IL hours,
or oftener If desired.
Thus We bave water and it's motive
force in diluting and carrying the
sewage out of the city or town, by
the means of underground pipes OF
tubes of calculated diameters and
gradients, laid to the irrigating fields,
where :he diluted and macerated
sewage is wasted through porous
pipes, laid with open joints for agri
cultural purposes This will be
found, and is accepted, ss the best
plan in securing speedy removal
| and disposal Of the principal matters
and liquid wastes, filth and etc.,
liable to decomposition. 1t will
secure and preserve the manurial
value o: the elements that have to be
utilized as food for the grains, grasses
and vegetables, increasing the fer
tiIity of soil and producing an iucred
ible yiald in farm products 1t will
do away with the baneful effects on
health, when the Accommodations in
towns, in forms of cesspools are per
mitted, either near or under the
habitation of the people, or in close
proximity thereto, and from broad
casting the solled water from kitchen,
laundry, bathes water closets and
chambers into .eceptscles about the
domiciles, as is known to be some
times thoughtless done.
At the point selected for the out
fail, there will be built to receive the
crude sewage, small reservoir, with
two compartments we'll ventilated
and separated by wire mesh work
partition, which will intercept and
retain all such solid matters that may
not have been thoroughly broken up
and we'll macerated in it's passage
through the pipes. From the first
compartment, the solid matter if any
be found therein retained, will DO re-
moved and burnt once per month.
The liquid nacerated waste, passes
through the mesh work into the next
compartment ct lower level, and
flows thence into what is known as
the main carrier pipe. from which it
flows into the distributing porous
pipes. which are placed and graded
in furrows to . depth Of 10 to II
inches below the surface Of the soil,
and sst in rows 4 feet from centeTs,
when the absorption Of their contents
i. speedily accomplished by the
absorbing sad constituent elements
of the porous soil. The area so used
and applied is known as the "irrigat-
ing field y
The liquid waste passing out of the
porus pipe. and joints of same, is all
taken up BY the roots of plants OF
veg.tstion All excess of moisture
passes to lower level through the
porosisy snd depth Of soil. filters
through it, and comes out 10 veins Of
clear filtered water. This is the process
Of farm drainage, by puri6ostion aod
filtration SO largely and successfully
carried out in many cities aud inland
Sowos, aud IS known 3s the net0oo OF
beverage disposal by Sub surface
irrigation. fos which the irrigs'iDg
field, certain area of land uexs to the
poios Of ousfall is prepared.
1t will give me pleasure With time if
you Wish it. to send you list Of the
cities in the United sta,es at the North
aud West, where THE method is entirely
used and proved very satisfactory and
successfully in every way
In this connection, | may state that
the cities Of Berlin aud Chailly, 10
Pruesis and near Paris, dispose Of the
sewage on irrigating fields. In the
farmer city. the fields are occupied by
the homes of 4, 900 farm laborers, who
are robust and healthy people, free from
all the diseases commoD to the cities.
