godam at the first onset died except one Kathgodam pony.
Also an aged Arab, " a pensioner, " running about the tonga
yard, was not affected. The Bojiaghat ponies were moved to
the new stable about a fortnight after the onset. No losses
occurred at Dogaon or Amprao except one at each place,
and these ponies had both been transferred from Bojiaghat
8 or 9 days previously. The usual method of diagnosis
appears to have been for the Veterinary Assistant to take tem-
peratures daily of all ponies at Kathgodam and Bojiaghat
stables, and any pony showing 101° F. or over, was tested by
fresh blood films under 1-6th power, by the Tonga Inspector.
The year is said to have been an exceptionally dry one
with hardly any rain after 27th August, and it has also been
a very bad autumn for malaria in Kathgodam.

Before the outbreak there were 106 ponies distributed
amongst the four lower stages (none stand at night at the
brewery). To replace losses new purchases arrived as fol-
lows :—

The ponies at Kathgodam were segregated about ¼ mile
from the other tonga ponies, about 100 feet above, on the
hill side in the jungle. During the time they had to wait at
Bojiaghat for the return tonga, they stood in the road. Not
one of these ponies which arrived on 22nd September became
affected, although regulary worked on the road and in contact
with 14 other ponies which became affected after the date of
their arrival.
