rom Lynn Canal will be definitely known.

"It is said by those familiar with the locality that the storms which
rage in the upper altitudes of the coast range during the greater part
of the time, from October to March, are terrific. A man caught in one of
them runs the risk of losing his life, unless he can reach shelter in a
short time. During the summer there is nearly always a wind blowing from
the sea up Chatham Strait and Lynn Canal, which lie in almost a straight
line with each other, and at the head of Lynn Canal are Chilkat and
Chilkoot Inlets. The distance from the coast down these channels to
the open sea is about 380 miles. The mountains on each side of the
water confine the currents of air, and deflect inclined currents in the
direction of the axis of the channel, so that there is nearly always a
strong wind blowing up the channel. Coming from the sea, this wind is
heavily charged with moisture, which is precipitated when the air
currents strike the mountains, and the fall of rain and snow is
consequently very heavy.

"In Chilkat Inlet there is not much shelter from the south wind, which
renders it unsafe for ships calling there. Capt. Hunter told me he would
rather visit any other part of the coast than Chilkat.

"To carry the survey from the island across to Chilkoot Inlet I had to
get up on the mountains north of Haines mission, and from there could
see both inlets. Owing to the bad weather I could get no observation for
azimuth, and had to produce the survey from Pyramid Island to Taiya
Inlet by reading the angles of deflection between the courses. At Taiya
Inlet I got my first observation, and deduced the azimuths of my courses
up to that point. Taiya Inlet has evidently been the valley of a
glacier; its sides are steep and smooth from glacial action; and this,
with the wind almost constantly blowing landward, renders getting upon
the shore difficult. Some long sights were therefore necessary. The
survey was made up to the head of the Inlet on the 2d of June.
Preparations were then commenced for taking the supplies and instruments
over the coast range of mountains to the head of Lake Lindeman on the
Lewes River. Commander Newell kindly aided me in making arrangements
with the Indians, and did all he could to induce them to be reasonable
in their demands. This, however, neither he nor any one else could
accomplish. They refused to carry to the lake for less than $20 per
hundred pounds, and as they had
