make any measurement to determine the relative size of the rivers; but
on his way out Dr. Dawson made these measurements, and his report,
before referred to, gives the following values of the cross sections of
each stream: Lewes, 3,015 feet; Teslintoo, 3,809 feet. In the same
connection he states that the Lewes appeared to be about 1 foot above
its lowest summer level, while the Teslintoo appeared to be at its
lowest level. Assuming this to be so, and taking his widths as our data,
it would reduce his cross section of the Lewes to 2,595 feet. Owing,
however, to the current in the Lewes, as determined by Dr. Dawson, being
just double that of the Teslintoo, the figures being 5.68 and 2.88 miles
per hour, respectively, the discharge of the Lewes, taking these figures
again in 18,644 feet, and of the Teslintoo 11,436 feet. To reduce the
Lewes to its lowest level the doctor says would make its discharge
15,600 feet.

[Footnote 6: The limited amount of prospecting that has been done on
this river is said to be very satisfactory, fine gold having been found
in all parts of the river. The lack of supplies is the great drawback to
its development, and this will not be overcome to any extent until by
some means heavy freight can be brought over the coast range to the head
of the river. Indeed, owing to the difficulties attending access and
transportation, the great drawback to the entire Yukon district at
present is the want of heavy mining machinery and the scarcity of
supplies. The government being aware of the requirements and
possibilities of the country, has undertaken the task of making
preliminary surveys for trails and railroads, and no doubt in the near
future the avenue for better and quicker transportation facilities will
be opened up.]
