ease peculiar to the species.

Meat Fly. breeding only in decay {
ing animal matter. Besides these {
there are several other kinds of flies s
that need not be mentioned here, for
they are not found in great numbers {
in this part of the continent. The /;
House Fly and the Stable Fly are
the species that infest our homes, {
and to them our attention will be
turned.
At one time I wondered where the
fly comes from every spring. My
superstition was that in the fall all
flies went into a state of coma when
cold weather came, and remained so
until early summer when they were
coaXed out of their insensibility by
the warmth of the sun, enjoyed the
summer, passed through the same
state again, a few dying of old age
and other infirmities, perishing by
the hand of man. The new supply
was supposed to have come from the
eggs laid by tn. large flies that APP
pear on the window panes in spring
and very early ummer. This theory
has been entirely dispelled by the
truth. And what is the truth? 1t
is this-when the flies persisted last
autumn millions of their eggs We're
in manure piles and other filthy
places. These have survived the cold
of the winter and are now awaiting
the warmth o. the sumer sun to hatch
them into activity. This will not
happen before the middle of June, eX-
cept in a few favored spots where
the heat of the sun will easily find
them.
Flies have three +. vorite breeding
places, garbage, decaying vegetable
matter, and stable manure, especial
3 ly from the horse barn. The last
3 mentioned is the favorite breeding re-
: sort of the fly. A female fly will lay
4 1920 eggs, if she does not lay 200, in
: the refuse from the horse barn. These
4 eggs hatch in midsummer in less
g than "a hours into the larval state
e In five days they reach the pupal
state, in which c. condition they remain
: a few days. end IN less than ten da
: they are flies, fully developed and
ready for business. 1t thus requires
s ten days for an egg % become a fly
Every ten days in summer we have {
new generation in addition to the
old ones. See how great is the in
crease from even one fly. If one fe'
male fly lays 100 eggs that result il
even 25 females, each in turn deposit
l. ling 100 eggs, how much of a pes
a does one fly become! The mischie
s. is incalcuable. One horse barn viii
d supply sufficient flies to trouble
e whole community. In this climate
vt we get six or seven generations o
flies q season. After the horse bar
d comes the garbage and the privy a
a breeding places for the fly. 1t i
not necessary to show the possibilitie
4. for evil these sources possess. Tn
house fly especially deposits its egg
le in UGH places, and that millios
S. of them come from these unwhole
If some and filthy breeding source
d there is not the slightest doubt. II
IS fact these are the breeding places o
% the pest, the horse barn the garbag
pill, and the clubhouse, the first beln!
s. the favorite. 1900 larvae have bee1
found in one pound of horse manure
200 have been found in a cubic incl
d of the offal.
d But what bearing has all this up
on the health OF the community? I
1T very direct one, as l shall now pro
g coed to show. Whenever a fly is seer
that is evidence of filth somewhere il
IS the neighborhood, for it breeds ant
st thrives in filth only. What bearing
has this on public health? Just this
i when the newborn fly shakes it,

Of its new life it is in an environ
p ment intentionally filthy. 1t has
p fed upon filth and disease germs, j
IS has gathered tiny clusters of fltl
efupon it's body and legs before it rises
into the air and makes straight fol
o the kitchen door. The door is open
ed, the fly enters and sails arousd the
room a few times, all covered with
filth and germs, scents the delicious
odor of the golden butter and makes
n a direct descent and lights upon 1T
$ What happens? 1t is needless to de.
It scribe what happens. The fly sinks
its nasty feet into the soft butter
