"Then how will you get over them?"
"I shall first take a cruise and see if I can find a negotiable gap, and
then leap it."
"What! Leap seven thousand feet?"
"No; you forget that we shall be over five thousand up when we take the
jump, and I have no doubt that we shall find a place where a thousand
feet or so more will take us over. That we shall rise easily with the
planes and propellers, and you will see such a leap as man never made in
the world before."
While he was speaking the Ariel had risen from the ground. and was
hanging a few hundred feet above the little plateau. He gave the signal
for the wheels to be lowered, and the propellers to set to work at
half-speed. Then he pulled the lever which moved the air-planes, and the
vessel sped away forwards and upwards at about sixty miles an hour.
Arnold headed her away from the mountains until he had got an offing of
a couple of miles, and then he swung her round and skirted the cliffs,
rising ever higher and higher, and keeping a sharp look-out for a
depression among the ridges that still towered nearly three thousand
feet above them.
When he had explored some twenty miles of the mountain wall, Arnold
suddenly pointed towards it, and said--
"There is a place that I think will do. Look yonder, between those two
high peaks away to the southward. That ridge is not more than six
thousand feet from the earth, and the Ariel can leap that as easily as
an Irish hunter would take a five-barred gate."
