NoTE on AUTHORITIES 171

cal Survey of Canada for 1875-6, 1888-9, and
especially 1876-7, are useful to illustrate his
routes. G. M. Dawson’s map in the Report
for 1876-7 is essential for tracing Mackenzie’s
course from the Fraser to the sea. An able
and convincing reconstruction of his course
on the Pacific from Bella Coola to the Rock
has been made by Captain R. P. Bishop in
Mackenzie’s Rock (Ottawa, Dept. of the
Interior, 1925).

This narrative has been based on these
and other printed sources. Captain Bishop
has generously allowed me to use some mate-
rial of his own, and has assisted me with
maps and advice. I here express my thanks
to him, and also to His Honour Judge Howay
for sending me some information, alluded to
in Chapter I, regarding the time of Macken-
zie’s arrival in Canada.
