Before undertaking work against the
early stages Of mosquitoes IN any Civ

racy all the places in which mozqui-
toes may breed. About houses the
greatest care must be taken 10 ex-

ground every permanent pool and ev-
cry swamp area should Be charted and
the method OF treatment determined
upon: permanent pools not used for
watering stock should be treated with
kerosene: swamp areas should be
drained small depressions should Be
filed with earth.
The best petroleum for the purpose
is found to be a light fuel oil The

In connection with another branch
OF his subject. Mr.. Howard relates
curious incident which be thinks may

mosquitoes. He says:
