The Dominion of the Air: The Story of Aerial Navigation

The following is a condensed account, gathered from Mr. Glaisher's own
narrative, of his first ascent, which has been already briefly sketched
in these pages by the hand of Mr. Coxwell. Very great difficulties were
experienced in the inflation, which operation appeared as if it would
never be completed, for a terrible W.S.W. wind was constantly blowing,
and the movements of the balloon were so great and so rapid that it was
impossible to fix a single instrument in its position before quitting
the earth, a position of affairs which, says Mr. Glaisher, "was by no
means cheering to a novice who had never before put his foot in the car
of a balloon," and when, at last, at 9.42 a.m., Mr. Coxwell cast off,
there was no upward motion, the car simply dragging on its side till
the expiration of a whole minute, when the balloon lifted, and in six
minutes reached the first cloud at an altitude of 4,467 feet. This cloud
was passed at 5,802 feet, and further cloud encountered at 2,000 feet
further aloft. Four minutes later, the ascent proceeding, the sun shone
out brightly, expanding the balloon into a perfect globe and displaying
a magnificent view, which, however, the incipient voyager did not allow
himself to enjoy until the instruments were arranged in due order, by
which time a height of 10,000 feet was recorded.
Mr. Glaisher apparently now had opportunity for observing the clouds,
which he describes as very beautiful, and he records the hearing of a
band of music at a height of 12,709 feet, which was attained in exactly
twenty minutes from the start. A minute later the earth was sighted
through a break in the clouds, and at 16,914 feet the clouds were
far below, the sky above being perfectly cloudless, and of an intense
Prussian blue.
By this time Mr. Glaisher had received his first surprise, as imparted
by the record of his instruments. At starting, the temperature of the
air had stood at 59 degrees. Then at 4,000 feet this was reduced to 45
degrees; and, further, to 26 degrees at 10,000 feet, when it remained
stationary through an ascent of 3,000 feet more, during which period
both travellers added to their clothing, anticipating much accession of
cold. However, at 15,500 feet the temperature had actually risen to 31
degrees, increasing to no less than 42 degrees at 19,500 feet.
