Part 32 (1/2)
No, the danger does not lie there!”
Cyrus Harding advanced towards the enormous causeway whose prolongation enclosed the narrow Shark Gulf. He could now sufficiently examine on this side the ancient channels of the lava. There was no doubt in his mind that the most recent eruption had occurred at a far-distant epoch.
He then returned by the same way, listening attentively to the subterranean mutterings which rolled like long-continued thunder, interrupted by deafening explosions. At nine in the morning he reached the corral.
Ayrton awaited him.
”The animals are cared for, Captain Harding,” said Ayrton.
”Good, Ayrton.”
”They seem uneasy, Captain Harding.”
”Yes, instinct speaks through them, and instinct is never deceived.”
”Are you ready?”
”Take a lamp, Ayrton,” answered the engineer; ”we will start at once.”
Ayrton did as desired. The onagas, unharnessed, roamed in the corral.
The gate was secured on the outside, and Cyrus Harding, preceding Ayrton, took the narrow path which led westward to the sh.o.r.e.
The soil they walked upon was choked with the pulverised matter fallen from the cloud. No quadruped appeared in the woods. Even the birds had fled. Sometimes a pa.s.sing breeze raised the covering of ashes, and the two colonists, enveloped in a whirlwind of dust, lost sight of each other. They were then careful to cover their eyes and mouths with handkerchiefs, for they ran the risk of being blinded and suffocated.
It was impossible for Cyrus Harding and Ayrton, with these impediments, to make rapid progress. Moreover, the atmosphere was close, as if the oxygen had been partly burnt up, and had become unfit for respiration.
At every hundred paces they were obliged to stop to take breath. It was therefore past ten o'clock when the engineer and his companion reached the crest of the enormous ma.s.s of rocks of basalt and porphyry which composed the north-west coast of the island.
Ayrton and Cyrus Harding commenced the descent of this abrupt declivity, following almost step for step the difficult path which, during that stormy night, had led them to Dakkar Grotto. In open day the descent was less perilous, and, besides, the bed of ashes which covered the polished surface of the rock enabled them to make their footing more secure.
The ridge at the end of the sh.o.r.e, about forty feet in height, was soon reached. Cyrus Harding recollected that this elevation gradually sloped towards the level of the sea. Although the tide was at present low, no beach could be seen, and the waves, thickened by the volcanic dust, beat upon the basaltic rocks.
Cyrus Harding and Ayrton found without difficulty the entrance to Dakkar Grotto, and paused for a moment at the last rock before it.
”The iron boat should be there,” said the engineer.
”It is here, Captain Harding,” replied Ayrton, drawing towards him the fragile craft, which was protected by the arch of a vault.
”On board, Ayrton!”
The two colonists stepped into the boat. A slight undulation of the waves carried it farther under the low arch of the crypt, and there Ayrton, with the aid of flint and steel, lighted the lamp. He then took the oars, and the lamp having been placed in the bow of the boat, so that its rays fell before them, Cyrus Harding took the helm and steered through the shades of the grotto.
The _Nautilus_ was there no longer to illuminate the cavern with its electric light. Possibly it might not yet be extinguished, but no ray escaped from the depths of the abyss in which reposed all that was mortal of Captain Nemo.
The light afforded by the lamp, although feeble, nevertheless enabled the engineer to advance slowly, following the wall of the cavern. A deathlike silence reigned under the vaulted roof, or at least in the anterior portion, for soon Cyrus Harding distinctly heard the rumbling which proceeded from the bowels of the mountain.
”That comes from the volcano,” he said.
Besides these sounds, the presence of chemical combinations was soon betrayed by their powerful odour, and the engineer and his companion were almost suffocated by sulphureous vapours.
