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 only about three-quarters of a mile of river, which
is not more than fifty or sixty yards wide, and two or three feet deep,
and is so swift and rough that navigation is out of the question.

"Lake Lindeman is about five miles long and half a mile wide. It is deep
enough for all ordinary purposes. Lake Bennet[3] is twenty-six and a
quarter miles long, for the upper fourteen of which it is about half a
mile wide. About midway in its length an arm comes in from the west,
which Schwatka appears to have mistaken for a river, and named Wheaton
River. This arm is wider than the other arm down to that point, and is
reported by Indians to be longer and heading in a glacier which lies in
the pass at the head of Chilkoot Inlet. This arm is, as far as seen,
surrounded by high mountains, apparently much higher than those on the
arm we travelled down. Below the junction of the two arms the lake is
about one and a half miles wide, with deep water. Above the forks the
water of the east branch is muddy. This is caused by the streams from
