ssist me in crossing from the Yukon to the
head of the Porcupine, or perhaps on to the Peel River. I then made a
survey of the Forty Mile River up to the canon. I found the canon would
be difficult of ascent, and dangerous to descend, and therefore,
concluded to defer further operations until the winter, and until after
I had determined the longitude of my winter post near the boundary, when
I would be in a much better position to locate the intersection of the
International Boundary with this river, a point important to determine
on account of the number and richness of the mining claims on the river.

"I left Forty Mile River for the boundary line between Alaska and the
Northwest Territories on the 12th September, and finished the survey to
that point on the 14th. I then spent two days in examining the valley of
the river in the vicinity of the boundary to get the most extensive view
of the horizon possible, and to find a tree large enough to serve for a
transit stand.

"Before leaving Toronto I got Mr. Foster to make large brass plates with
V's on them, which could be screwed firmly to a stump, and thus be made
to serve as a transit stand. I required a stump at least 22 inches in
diameter to make a base large enough for the plates when properly placed
for the transit. In a search which covered about four miles of the river
bank, on both sides, I found only one tree as large as 18 inches. I
mention this fact to give an idea of the size of the trees along the
river in this vicinity. I had this stump enlarged by firmly fixing
pieces on the sides so as to bring it up to the requisite size. This
done, I built around the stump a small transit house of the ordinary
form and then mounted and adjusted my transit. Meanwhile, most of the
party were busy preparing our winter quarters and building a magnetic
observatory. As I had been led to expect extremely low temperatures
during the winter, I adopted precautionary measures, so as to be as
comfortable as circumstances would permit during our stay there.

DESCRIPTION OF THE YUKON, ITS AFFLUENT STREAMS, AND THE ADJACENT
COUNTRY.

"I will now give, from my own observation and from information received,
a more detailed description of the Lewes River, its affluent streams,
and the resources of the adjacent country.

"For the purpose of navigation a description of the Lewes River begins
at the head of Lake Bennet. Above that point, and between it and Lake
Lindeman, there is on
