territory lying between Fingerboard
and Richmond roads, adjacent to the
inks of the Fox Hills Golf Club, were

the ponds we're moved down, raked In
to heaps and sprayed.
The start from the Quarantine
Boarding Station was made yesterday
morning at 10 o'clock and the force
was the same as on Monday. DR.. Doty
was in charge Of the expedition, which
consisted OF three sanitary policemen
and five laborers, all prepared for rain.
The oil tank wagon, which was
emptied on Monday. was filed with q
hundred gallons OF crude petroleum.
Another wagon carried the party and
the apparatus. including the spraying
raft, force pump, long lengths of gar
den hose and scythes.
When a pond was reached the tank
wagon was driven as close as possible
to its banks, the raft was fioated with
the gridiron spraying apparatus sus-

While the men were engaged in this
work DR.. Doty visited some OF he
ponds treated on Monday and also in.
spected a number Of houses in which
cases of malarial fever had been re-
ported. In one OF these he secured
mosquitoes. the anopheles which have
been found to bear malarial germs, and
later in the day these were examined
in his laboratory at quarantine and
found to be bearers OF the germs
DR.. Doty said last evening that he

mosquitoes at work, and two women
were found wheeling babies about the
shores Of the pond.
