worse Cnan the curse or SerpentS or

the ''grevious swarm OF fiies'

the Israelite in that long struggle
for freedom. In the simple and tell
ing words Of the narrative, 1.-THE land

do not need to be told that this
fly Of Egypt was perhaps not the
musca domestica, our common house
fly, but some more noxious variety
known to the East. It is enough to
know that the house fly is found in
every land and cline, and that it
was quite capable of proving "gre-
vious'' and "corrupting" on that oc-
casion. Because of it's intimate as
sociation with man, it is the only
variety worth considering in it's re-.
lations to health-at least in our
climate. OF 23,087 flies caught in
dining rooms in the year 1905, 9S.8
per cent. were found to be the COM
mon house fly.
This insect, with it's air pump feet
and its faceted eyes, may be a thing
of beauty to the entomologist; it's
drowsy buzzing on the pane has even
inspired poets; but we may be sure
that the poet sang of some fly
reused to life in early March by a
day Of premature heat. But taken
collectively, and in summer, the fly
is hateful creature. Not only is it
responsible for lines of worry in the
housekeeper's face, but it has been
proved to be a serious menace to
health.
To begin with, it's origin and hab-
its are such as to put us on our
guard. 1t lays its eggs in excrement,
preferring horse manure, but if that
does not offer readily using any
other. 1t feeds on the same and on
the sputum of diseased throats and
lungs. on refuse of all kinds, and it
bears on it's hairy feet and legs par
ticles Of these substances.
Thanks to the science of bacteriol-
ogy, our case against the fly is no
longer guesswork-it has been made
to walk across the sterile gelatine
plate, and the microscope has later
told US what it fetches and carries.
Unlike the mosquito, the house fly is
not a biter-but it has it's own way
OF carrying contagion. It deposits,
wherever it goes, disease: and dis
ease germs may abound in it's breed
Ing and feeding places. On the joint
Of meat exposed for sale by the
butcher, on the bread and sweet
meats of the confectioner's counter,
on the edge of the milk pail, on the
kitchen and dining room tables, they
have been found.
To understand fully the possible
danger of allowing this insect access
20 our food supplies, we must remem-
Der that in the diseases called en-
teric-those affecting the intestinal
tract, such as cholera, dysentary and
typhoid fever-multitudes of germs
peculiar to the disease are voided
not only during the attack, but for
some days before the disease is rec
ognized and for considerable periods
of time after recovery, and since the
:ontagion is spread from person to
another solely by these germs as they

The water supply from contamination
and to forbid the sale of milk from
the dairy farms where any conta-
gion exists is well recognized as the
first duty Of the Health Board; but
comparatively recent is the knowl-
edge that flies also carry the germs
Of these diseases.
In 1888 Dr.. Nuttall had shown
that flies transmitted cholera. In
1895 DR.. Kober, of Washington, said
that typhoid fever was spread by
their aid in old-fashioned non-sew-
cred dwellings, but not until the
Cuban war, three years later, was
this transmission proved on such a
scale as to. convince the medical pro-
tession. 1t was then that we began
our real acquaintance with the fly
and all his works.
Not only does the fly carry about
on his feet and legs any disease

ally given the disease from nine to

This is very important point, as
It establishes on new ground the dam

ever flies can have access to the
sputum. A lull in the efforts to pre-
rent public splitting came on the dis
