CHAPTER XXIV. ANDREE AND HIS VOYAGES
Among many suggestions, alike important and original, due to Major
Baden-Powell, and coming within the field of aeronautics, is one having
reference to the use of balloons for geographical research generally and
more particularly for the exploration of Egypt, which, in his opinion,
is a country possessing many most desirable qualifications on the score
of prevailing winds, of suitable base, and of ground adapted for such
steering as may be effected with a trail rope. At the Bristol meeting of
the British Association the Major thus propounded his method: "I should
suggest several balloons, one of about 60,000 cubic feet, and, say,
six smaller ones of about 7,000 cubic feet; then, if one gets torn or
damaged, the others might remain intact. After a time, when gas is
lost, one of the smaller ones could be emptied into the others, and the
exhausted envelope discharged as ballast; the smaller balloons would be
easier to transport by porters than one big one, and they could be more
easily secured on the earth during contrary winds. Over the main balloon
a light awning might be rigged to neutralise, as far as possible, the
changes of temperature. A lightning conductor to the top of the balloon
might be desirable. A large sail would be arranged, and a bifurcated
guide rope attached to the end of a horizontal pole would form
an efficient means of steering. The car would be boat-shaped and
waterproof, so that it could be used for a return journey down a river.
Water tanks would be fitted."
The reasonableness of such a scheme is beyond question, even without the
working calculations with which it is accompanied; but, ere these words
were spoken, one of the most daring explorers that the world has known
had begun to put in practice a yet bolder and rasher scheme of his own.
The idea of reaching the North Pole by means of balloons appears to have
been entertained many years ago. In a curious work, published in Paris
in 1863 by Delaville Dedreux, there is a suggestion for reaching the
North Pole by an aerostat which should be launched from the nearest
accessible point, the calculation being that the distance from such
a starting place to the Pole and back again would be only some 1,200
miles, which could be covered in two days, supposing only that there
could be found a moderate and favourable wind in each direction. Mr. C.
G. Spencer also wrote on the subject, and subsequently Commander
