They wished to reach the second cone, and proceeding along the ridge of the spurs seemed to be the best way by which to gain it.
"We are on volcanic ground," Cyrus Harding had said, and his companions following him began to ascend by degrees on the back of a spur, which, by a winding and consequently more accessible path, joined the first plateau.
The ground had evidently been convulsed by subterranean force.Here and there stray blocks, numerous debris of basalt and pumice-stone, were met with.In isolated groups rose fir-trees, which, some hundred feet lower, at the bottom of the narrow gorges, formed massive shades almost impenetrable to the sun's rays.
During the first part of the ascent, Herbert remarked on the footprints which indicated the recent passage of large animals.
"Perhaps these beasts will not let us pass by willingly," said Pencroft.
"Well," replied the reporter, who had already hunted the tiger in India, and the lion in Africa, "we shall soon learn how successfully to encounter them.But in the meantime we must be upon our guard!"They ascended but slowly.
The distance, increased by detours and obstacles which could not be surmounted directly, was long.Sometimes, too, the ground suddenly fell, and they found themselves on the edge of a deep chasm which they had to go round.Thus, in retracing their steps so as to find some practicable path, much time was employed and fatigue undergone for nothing.At twelve o'clock, when the small band of adventurers halted for breakfast at the foot of a large group of firs, near a little stream which fell in cascades, they found themselves still half way from the first plateau, which most probably they would not reach till nightfall.From this point the view of the sea was much extended, but on the right the high promontory prevented their seeing whether there was land beyond it.On the left, the sight extended several miles to the north; but, on the northwest, at the point occupied by the explorers, it was cut short by the ridge of a fantastically-shaped spur, which formed a powerful support of the central cone.
At one o'clock the ascent was continued.They slanted more towards the southwest and again entered among thick bushes.There under the shade of the trees fluttered several couples of gallinaceae belonging to the pheasant species.They were tragopans, ornamented by a pendant skin which hangs over their throats, and by two small, round horns, planted behind the eyes.Among these birds, which were about the size of a fowl, the female was uniformly brown, while the male was gorgeous in his red plumage, decorated with white spots.Gideon Spilett, with a stone cleverly and vigorously thrown, killed one of these tragopans, on which Pencroft, made hungry by the fresh air, had cast greedy eyes.
After leaving the region of bushes, the party, assisted by resting on each other's shoulders, climbed for about a hundred feet up a steep acclivity and reached a level place, with very few trees, where the soil appeared volcanic.It was necessary to ascend by zigzags to make the slope more easy, for it was very steep, and the footing being exceedingly precarious required the greatest caution.Neb and Herbert took the lead, Pencroft the rear, the captain and the reporter between them.The animals which frequented these heights--and there were numerous traces of them--must necessarily belong to those races of sure foot and supple spine, chamois or goat.Several were seen, but this was not the name Pencroft gave them, for all of a sudden--"Sheep!" he shouted.
All stopped about fifty feet from half-a-dozen animals of a large size, with strong horns bent back and flattened towards the point, with a woolly fleece, hidden under long silky hair of a tawny color.
They were not ordinary sheep, but a species usually found in the mountainous regions of the temperate zone, to which Herbert 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.
