The Yakima herald. [volume] (North Yakima, W.T. [Wash.]) 1889-1914, 1909-06-09

Upon Goldberg's blackboard, Dor
rowed for the occasion, he did sums
in many ciphers to show the astound-
ing productivity of the house1y. From
a fly which laid 120 eggs (the average
number) the first of April, it is pos
sible to have 100000, 900, 900, 0O0,-
900, 900 flies by the end of the sum-
mer. The fly lays its eggs in manure,
preferably horse manure. They hatch
in from three to twelve hours. In five
days the maggots become pupae and
it takes the pupae five days more to
become the fly. Thus there may be a
new generation of flies every ten days.
Water All Right
ut is not the water system that is
the matter with North Yakima" said
Pref. Melander, but the flies think
the water system here is as nearly
perfect as one could wish. 1 don't
say that it always will be so, but 1
will say that 1 do not think that one
of the cases of typhoid here is caused
by the water. Experiments have been
made by washing flies into sterilized
water, and taking a drop of this water
and making cultures. From these
experiments it has been figured that
a fly caught in a home carried A.
$50 bacteria on his legs, wings and
back. One taken from a COW stable
had 100000; a fly from a pig pen,
$4,000, and fly found in a swill bar
rel was actually carrying around the
enormous number of 100000 bacter-
ia. The difference between the six
million and a half which the fly had
in the swill barrel and the 47,000
which it had in your house, gives you
the number it has shaken off on the
sugar. A fiys mouth is so constructed
that he sucks his food and can eat
only liquids or food which he has
made liquid. A tuberculosis germ
will remain alive in =. fly speck for fif-
teen days. If a dog has hydrophobia,
you kill it. If coyote or wolf steals
your chickens, you kill it, But of
flies, which kill you, you make a
house pet. You tolerate them be-
cause your ancestors have tolerated
them, because you are apathetic, lack
interest. If you have typhoid fever,
it simply means that you hove eaten
some ones excrement.
Have Lids That Fit.
Have lids on your swill barrels
that fit. / looked about the alleys a
bit today. In a number of cases
where I found swil barrels, there
weren't such lot of them, either, the
lids didn't fit. But above all things,
take care of the horse manure. Fol-
low the city ordinance and go it one
better Not only put the stable man
ure in boxes, but get a cover for the
box. Screen your outhouses."
Prof. Melander made a diagram
based on figures of the North Yallim a
health statistics for the past two
years showing the greatest occurrence
of typhoid and other bowel diseases
to be from August to November. The
same chart showed the curve of the
greatest prevalence of flies and the
two curves We're nearly identical, the
disease curve following the f1v curve
by about a month. He showed how
seven cases of typhoid developed last
year in six weeks within three blocks
here in the neighborhood of Jeffer-
son, Balsom and Brown streets, and
how twelve cases in the Mckee devel-
oped in a month, through flies. and
uncleanly methods of living.
ut is criminal negligence to allow
flies in a house where there are child
rem to be brought up" said Prof. Me-
lander.
