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 nnumbers|
in this part of the continent. The /;
House Fly and the Stable Fly are
the species that infest our homes, {
and to them III attention will be
turned.
At one time l wondered where the
fly ome from every spring. My
supposition 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 oft 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 were
in manure piles and other filthy

of tho winter and are now awaiting
the warmth O. the sumner sun to hatch
them into activity. This will not
4 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
= ly from the horse barn. The last
: mentioned is the favorite breeding re-
sort of the fly. A female fly VIII lay
4 1870 eggs, if she does not lay 200, in
: the refuse from the horse barn. These
! eggs hatch in midsummer in less
2 than "a hours into the larval state
e In five days they reach the pupa
state, in which c. ndition they remain
: a few days. and IN less than ten da
they are flies, fully developed ant
ready for business. 1t thus require:
S ten days for an egg % become a fly
Every ten days in summer we have
new generation in addition to thu
old ones. See how great is the in
crease from even one fly. If one fe
male fly lays 1870 eggs that result il
even 25 females, each in turn deposit
fling 100 eggs, how much of a pes
a does one fly become! The mischie
s. is incalcuable. One horse barn will
d supply sufficient flies to trouble
whole community. In this climat
vt we get six or seven generations o
n 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
/. for evil these sources possess. TIL
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. i
IS fact these are the breeding places o
o the pest, the horse barn the garbag
and the clubhouse, the first belni
the favorite. 1900 larvae have bee
r. found in one pound of horse manure
200 have been found in a cubic inc
OF the offal.
q But what bearing has all this up
2 on the health of the community?
very direct one, as l shall now pro
g coed to show. Whenever a fly is see
that is evidence of filth somewhere il
the neighborhood, for it breeds an
thrives in filth only. What bearing
has this on public health? Just thi
when the newborn fly shakes it
y wings and scrapes it's feet in the jo.
OF its new life it is in an environ
p ment intentionally filthy. 1t ha'
fled upon filth and disease germs, !
has gathered tiny clusters of fltl
Q tupon it's body and legs before it rise:
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 witt
filth and germs, scents the deliciou:
t odor of the golden butter and make!
a direct descent and lights upon it
8 What happens? 1t is needless to de-
scribe what happens. The fly sink:
its nasty feet into the soft butter
and then scrapes them off, leaving
d some of it's filth and germs in thai
golden brick that cost you thirty
cents, making it more to be Stunned
s than the proverbial gold bricl
sometimes offered in the form
of watered stocks and bonds
