The infection Of yellow fever is car.
riea by mosquitoes, and by no other
means is the infection spread.
+ Persons take the disease by being
bitten by mosquitoes that have pre-
viOuslT bitten a yellow fever patient.
TIE mosquitoes to become infected
must bite a yellow fever patient dur
ing the first three days Of his attack.
/ These first three days, therefore, are
the most important time for prevent
ing the access of mosquitoes to a few
er patient.
1t is often difficult to decide during
the first three days whether patient
has yellow fever; hence the necessity
IN threatened communities of placing
a mosquito bar imediatelv around
every patient who has fever of any
kind, and for three days at least.
Facts About Screening.
/ /. The netting used should have
meshes fine enough tOspreVent the pas

the netting they should be killed in
SHE and not merely driven or shaken
out.
Z. All cases Of fever should be
promptly reported to the local health

Facts Bearing on Mosquito Destruction
/ Mosquitoes live in the vicinity
il. which they breed. They 90 not Of
ten fly a long distance.
2. Mosquitoes breed only in water
usually in artificial collections OF
fresh water.
8. The young mosquito or wriggler
lives in water at least seven to twelve
4. Although the wrigglers live in
water. they must come frequently to
the surface to breathe.
). Coal oil on the surface Of the
water prevents the wrlgglers from
breathing.
g. Destroy the breeding places and
you will destroy the mosquitoes
7. Empty the water from all tubs,
buckets, cans. flower pots, vases, once
every fOrty-eight hours.
s. Fill or drain all ponds, ditches,
untitled postpoles, and the like.

10. Treat with coal oil all standing
water which cannot be screened or
drained q ounce of oil will cover Is
square feet of surface). The oil does
not effect the water for use if the wa
ter is drawn from below.
Ii. Where oil is applied to standing
water it must be distributed evenly
over the surface.
u. Put fine wire netting over els
terms. wells. and tanks Of water in

able to put oil, such as watering
t~oughs for stock. lily ponds, and so
forth. can be kept free from wrigglers
by putting in goldfish or minnOws.
IA. Clean away all weeds, grass and
bushes about bitches, ponds, and other
possible breeding places. since these
afford a hiding place for the mOsqui-
toes.
Is. Clean up vacant lots and back
Yards of all cans, tins, Bottles, and rub
bish
Is. First do away with, or treat, all
places where mosquitoes are known
to breed and then begin 10 work on
places where they might breed.
II. Inspect ana treat with coal oil
cutters. culverts, bitches. manholes,
catching basins, cts, along the road

3 screened.
IS. Houses should be cleared of
4 mosquitoes by burning 1 pound Of in
