| first chamber of the septic tank.
Since they are found in limited guam
titles in all sewage and multiply
very rapidly, it Is not necessary to
take special pains In giving them a
start. Soon after the tank is in
operation the bacteria form a scum
over the surface of the liquid dense
enough to exclude the air. In or
der that this scum be kept intact the
sewage is made to enter the first
chamber several inches below the
surface. One or more battle boards
are used and the liquid as it leaves
the first chamber is taken from a
point several inches below the sur-
face in order to keep the surface
quiet. After entering the first cham
Der the solid particles settle to the
bottom and remain until changed to
! a gas or liquid by the bacteria.
AS the sewage enters the tank III
equal amount of liquid is forced
over into the second chamber. This
liquid is not chemically pure 1t
may contain all the disease germs
that originally found their way into
the tank. At this point second form
of bacteria start their work.
The second chamber is only about
one-third the size of the first one.
1t fills with liquid to certain poinI
or until enough head is obtained to
start the siphon working. 1t is then
siphoned out until air is again adj
mitted under the bell Of the siphon.
In this manner liquid is discharged
at intermittent intervals into the
disposal system. The aerobic bac-
terra require air m order to live, and

the intermittent action provides
breathing spells for them.
The disposal system consists of
from IS feet to SO feet of loose-laid
drain tile per person using the tank
depending upon the capacity of the
soil to take up water. The tileI may
be laid in one or more lines and
should be from II to IS inches be-
low the surface. If the soil is very
dense the bottom OF the trench
should be filed with few inches
Of cinders or gravel. The siphon in,
Sures the use of the entire system,
providing against the soil just out
side the tank becoming sour, due to
almost constant discharges from the
tank keeping it wet.

show it to contain less impurity
than most we'll water.
The septic tank may be installed
anywhere outside the foundation
walls. the closer to the house the
better, since expensive sewer tile
and water-tight joints must be used
between the soil pipe and the tank.
It is considered best to cover the
tank with about Is inches of dirt.
but that is not necessary. There is
very little danger Of freezing, bot
hot dish water ETC., are continually
being enptied into the tank. This
also insures against the tile lines
freezing IN the disposal system, even
though they are above the frost line.
The disposal system may be locat-
ed in the yard, garden or where
ever convenient. 1t is claimed that
the plant food and the moisture adj
ded to the garden in this manner
will pay for the entire installation
in from one to three years. Care
should be taken not to run the tile
lines near shrubs or trees, since
roots will clog them in a short time
1t is not advisable to discharge
sewage even from a septic tank di-
rectly into a stream or lake where
the water is used by either man or
animals for drinking purposes. 1t
is not Objectionable to discharge into
a line of drain tile where it would
be necessary for the sewage to travel
a considerable distance before reach
ing the outlet.
Treating a Case of Inflamed Udder
A. S. j., Charleston, Ca, writes:
l would like to know how to
treat a milk cake in a cows

the udder for some time, and
as she will bring a calf in about
two weeks I am afraid I will!

her udder. Any assistance will
be greatly appreciated.
Caked udder is not an uncommon
trouble in the case Of COWS. 1t may
occur at any stage of the lactation
period. 1t is most likely to happen
in the case Of young animal or COWS
which have recently freshened. The
trouble is due to an inflammation
of part or all of the udder. This
may arise from various causes, such
as bruises or injuries. At the time
of parturition the u6der is likely to
become very much inflameG, and it

r.ly. Bathing with hot water and
kneading at this time and milking
out thoroughly will often effect con
siderable relief. The process which
you should follow is to foment the
udder three times a day with hot
water. Use it just as hot as the
hands can bear, and continue the
treatment for twenty minutes at
