INVESTIGATION OF AN OUTBREAK OF HORSE
        SURRA WITH RESULT OF TREATMENT
             WITH ATOXYL, TARTAR EMETIC,
               MERCURY AND OTHER DRUGS.

DURING the latter months of 1907, the tonga and ekka
ponies working on the Kathgodam-Naini Tal road, U. P.,
suffered heavy losses from Surra. The outbreak commenced,
as is usually the case, soon after the appearance of the rains,
in July. Unfortunately, no opportunity of studying the
outbreak occurred until September. Early in that month,
Mr. Cross, the Assistant Bacteriologist, was directed to carry
out this work, but, owing to pressure of work at the
Laboratory, he was recalled after ten days and Mr. Leese
(Officer Investigating Camel Diseases) was deputed for this
duty.

SUMMARY OF REPORTS BY THE ABOVE OFFICERS.

The tonga service runs from the Railway Station, Kath-
godam, to Naini Tal Brewery, a distance of 12 miles. There
are four halting stages where the ponies are changed and stab-
led: Kathgodam, Bojiaghat, Dogaon and Amprao. About
one hundred and thirty ponies are constantly employed on
this work.

Position of Stables.—The jungle comes up to about
30 yards on one side of Kathgodam stable; there are several
hollows where water is said to collect during the rains within
50 yards from the stable, but no water was there between
20th September and 23rd October. The distance of stable
from road is 80 yards.

Bojiaghat old stable is within a few yards of the road, but
considerably below that level; on three sides there is thin
jungle; about 100 yards from the stable and on a much
lower level is a marshy hollow containing stagnant water.
On the road, just above, and on the same side as the stable,
is a bullock camping-ground, used far more in the day time
