REPORTS OF THE ‘SLEEPING SICKNESS’ 
EXPEDITION TO THE ZAMBESI 
FOR THE YEARS 1907-1908 
BY 
ALLAN KINGHORN, M.B, Toronto, 
JOHNSTON COrX)NlAL FELLOW, UNIVERSITY OF LIVERPOOL 
AND 
R. EUSTACE MONTGOMERY, M.R.C.V.S. 
OBJECTS OF THE EXPEDITION 
The objects of the Expedition were to determine to what extent 
sleeping- siclcness had invaded British South African Territory, to 
map out the distribution of tsetse flies and to advise on means for 
checking the spread of sleeping sickness. 
The Expedition was put under the charge of Dr. Kinghom and 
Mr. Montgomery—the latter paying special attention to Trypano¬ 
somiasis in animals. 
The first letter from the Expedition is dated November 22, 1907, 
from N’dola, North-Western Rhodesia, and is from Mr. Montgomery, 
relating to a correspondence between the members of the Expedition 
and Mr. Moffat, the local representative of the various Copper 
Properties in North-West Rhodesia and the General Superintendent 
of the Bechuanaland Coaling Co. 
Mr. Moffat, who has taken a very keen interest in the sleeping 
sickness question, has helped the members of the Expedition in 
every way. 
In a letter from Broken Hill, Rhodesia, dated October 23, 
1907, and directed to Mr. Montgomery, Mr. Moffat states the 
following in regard to the question of the tsetse fly and big game : — 
‘ I am especially keen on the question as to the connection between 
the game and the fly, though I am confident that there is a close 
connection, and that the fly will not exist long without the game, 
there are undoubtedly here and there spots where there is little or 
no game where the fly still remains. This possibly is only temporary ; 
the fly will probably disappear from such places shortly.' Mr. Moffat 
then proceeds to discuss the question of establishing an Observation 
Camp at Broken Hill, asking for particulars of the probable cost of 
maintenance. In a letter dated November 21, 1907, from Broken 
Hill, Mr. Montgomery replied: —
