bert gave the
name of the musmon.

"Have they legs and chops?" asked the sailor.

"Yes," replied Herbert.

"Well, then, they are sheep!" said Pencroft.

The animals, motionless among the blocks of basalt, gazed with an
astonished eye, as if they saw human bipeds for the first time. Then
their fears suddenly aroused, they disappeared, bounding over the rocks.

"Good-bye, till we meet again," cried Pencroft, as he watched them, in
such a comical tone that Cyrus Harding, Gideon Spilett, Herbert, and Neb
could not help laughing.

The ascent was continued. Here and there were traces of lava. Sulphur
springs sometimes stopped their way, and they had to go round them. In
some places the sulphur had formed crystals among other substances, such
as whitish cinders made of an infinity of little feldspar crystals.

In approaching the first plateau formed by the truncating of the lower
cone, the difficulties of the ascent were very great. Towards four
o'clock the extreme zone of the trees had been passed. There only
remained here and there a few twisted, stunted pines, which must have
had a hard life in resisting at this altitude the high winds from the
open sea. Happily for the engineer and his companions the weather was
beautiful, the atmosphere tranquil; for a high breeze at an elevation of
three thousand feet would have hindered their proceedings. The purity
of the sky at the zenith was felt through the transparent air. A perfect
calm reigned around them. They could not see the sun, then hid by the
vast screen of the upper cone, which masked the half-horizon of the
west, and whose enormous shadow stretching to the shore increased as
the radiant luminary sank in its diurnal course. Vapor--mist rather than
clouds--began to appear in the east, and assume all the prismatic colors
under the influence of the solar rays.

Five hundred feet only separated the explorers from the plateau, which
they wished to reach so as to establish there an encampment for the
night, but these five hundred feet were increased to more than two miles
by the zigzags which they had to describe. The soil, as it were, slid
under their feet.

The slope often presented such an angle that they slipped when the
stones worn by the air did not give a sufficient support. Evening
came on by degrees, and it was almost night when Cyrus Harding and his
companions, much fatigued by an ascent of seven hours, arrived at
the plateau of the first cone. It was then
