was published in 1798 and Mackenzie's ‘“‘Voyage’’ in 1801.
lt would therefore seem that the footnotes were added
some four years or more after the journal was written.
It is not surprising that errors occurred when after that
lapse of time Mackenzie tried to plot his route upon
Vancouver's chart.

During the summer of 1923 the author, Captain
R. P. Bishop, a trained surveyor, who was then in the
service of the Land Department of the Government of
British Columbia and engaged in professional work in the
vicinity of Bella Coola, was instructed to make an effort
to locate the rock which was the westernmost point reached
by Mackenzie. The interest with which he undertook
the task and the skill with which he performed it are well
shown by the annexed report.

Captain Bishop has pursued the rational course of
going over the ground (or rather, the water) traversed by
Mackenzie from Bella Coola to the rock on which he made
his “brief memorial,’ taking as his guide the courses and
distances given in the journal and utilizing on every
occasion the “checks’’ therein contained. Following this
plan he found but three difficulties, outside of those caused
by the errors in the footnotes. (1) In one instance Mac-
kenzie gives a course of one-quarter of a mile, whereas on
the ground the distance is about four miles. The explana-
tion here seems obvious. (2) The “island,” as Mackenzie
calls it, opposite Point Edward on King Island is in reality
a meniaaula: The photographic view which is reproduced
in the paper shows how easily its real nature could be
mistaken. This is a frequent type of error on the part of
early explorers. The classical example in British Columbia
is that of Vancouver who denominates the peninsula near
the City of Vancouver, now known as “Stanley Park,” as
an “island.” (3) The most serious difficulty is that the
distance along the north shore of King Island is con-
siderably greater than Mackenzie makes it. The author’s
suggestion on this point is that owing to the danger in
which the party then was Mackenzie inadvertently failed
to record one course and distance.

But after all, these difficulties are more apparent than
real, for an examination of Mackenzie's map shows, as
does the working out of his courses and distances that
The Rock must be sought somewhere in the vicinity of
