em from fogging when
the cold on the outside of the glass condenses the moisture of
perspiration on the inside of the glass. We use double-glazed sashes
with an air space between on all windows in our houses in Alaska and
find ourselves no longer incommoded by frost on the panes; some
adaptation of this principle should be within the skill of the optician
and would remove a very troublesome defect in all snow-glasses.

If some one would invent a preventive against shortness of breath as
efficient as amber glasses are against snow-blindness, climbing at great
altitudes would lose all its terrors for one mountaineer. So far as it
was possible to judge, no other member of the party was near his
altitude limit. There seemed no reason why Karstens and Walter in
particular should not go another ten thousand feet, were there a
mountain in the world ten thousand feet higher than Denali, but the
writer knows that he himself could not have gone much higher.

FOOTNOTE:

[4] The dotted line on the photograph opposite page 346 of Mr. Belmore
Browne's book, "The Conquest of Mt. McKinley," does not, in the writer's
opinion, represent the real course taken by Professor Parker, Mr.
Belmore Browne, and Merl La Voy in their approach to the summit, and it
is easy to understand the confusion of direction in the fierce storm
that descended upon the party. If, as the dots show, the party went to
the summit of the right-hand peak, they went out of their way and had
still a considerable distance to travel. "Perhaps five minutes of easy
walking would have taken us to the highest point," says Mr. Browne. It
is probably more than a mile from the summit of the snow peak shown in
the picture to the actual summit of the mountain. One who took that
course would have to descend from the peak and then ascend the horseshoe
ridge, and the highest point of the horseshoe ridge is perhaps two
hundred feet above the summit of this snow peak. In the opinion that
Professor Parker expressed to the writer, the dotted lines should bear
much more to the left, making directly for the centre of the horseshoe
ridge, which is the obvious course. But it should again be said that men
in the circumstances and condition of this party when forced to turn
back, may be pardoned for mistaking the exact direction in which they
had been proceeding.

CHAPTER VI

THE RETURN

The next day was another bright, cloudless day, the second and last of
them. Perhaps never
