The last of the three mysterious documents had represented that Gallia, in conformity with Kepler's second law, had traveled along her orbit during the month of March twenty millions of leagues less than she had done in the previous month; yet, in the same time, her distance from the sun had nevertheless been increased by thirty-two millions of leagues.
She was now, therefore, in the center of the zone of telescopic planets that revolve between the orbits of Mars and Jupiter, and had captured for herself a satellite which, according to the document, was Nerina, one of the asteroids most recently identified.
If thus, then, it was within the power of the unknown writer to estimate with such apparent certainty Gallia's exact position, was it not likely that his mathematical calculations would enable him to arrive at some definite conclusion as to the date at which she would begin again to approach the sun? Nay, was it not to be expected that he had already estimated, with sufficient approximation to truth, what was to be the true length of the Gallian year?
So intently had they each separately been following their own train of thought, that daylight reappeared almost before the travelers were aware of it. On consulting their instruments, they found that they must have traveled close upon a hundred leagues since they started, and they resolved to slacken their speed. The sails were accordingly taken in a little, and in spite of the intensity of the cold, the explorers ventured out of their shelter, in order that they might reconnoiter the plain, which was apparently as boundless as ever.
It was completely desert; not so much as a single point of rock relieved the bare uniformity of its surface.
"Are we not considerably to the west of Formentera?" asked Servadac, after examining the chart.
"Most likely," replied Procope. "I have taken the same course as I should have done at sea, and I have kept some distance to windward of the island;we can bear straight down upon it whenever we like.""Bear down then, now; and as quickly as you can."The yawl was at once put with her head to the northeast and Captain Servadac, in defiance of the icy blast, remained standing at the bow, his gaze fixed on the horizon.
All at once his eye brightened.
"Look! look!" he exclaimed, pointing to a faint outline that broke the monotony of the circle that divided the plain from the sky.
In an instant the lieutenant had seized his telescope.
"I see what you mean," said he; "it is a pylone that has been used for some geodesic survey."The next moment the sail was filled, and the yawl was bearing down upon the object with inconceivable swiftness, both Captain Servadac and the lieutenant too excited to utter a word.
Mile after mile the distance rapidly grew less, and as they drew nearer the pylone they could see that it was erected on a low mass of rocks that was the sole interruption to the dull level of the field of ice. No wreath of smoke rose above the little island; it was manifestly impossible, they conceived, that any human being could there have survived the cold;the sad presentiment forced itself upon their minds that it was a mere cairn to which they had been hurrying.
Ten minutes later, and they were so near the rock that the lieutenant took in his sail, convinced that the impetus already attained would be sufficient to carry him to the land.
Servadac's heart bounded as he caught sight of a fragment of blue canvas fluttering in the wind from the top of the pylone:
it was all that now remained of the French national standard.
At the foot of the pylone stood a miserable shed, its shutters tightly closed. No other habitation was to be seen; the entire island was less than a quarter of a mile in circumference;and the conclusion was irresistible that it was the sole surviving remnant of Formentera, once a member of the Balearic Archipelago.
To leap on shore, to clamber over the slippery stones, and to reach the cabin was but the work of a few moments.
The worm-eaten door was bolted on the inside.
Servadac began to knock with all his might. No answer.
Neither shouting nor knocking could draw forth a reply.
"Let us force it open, Procope!" he said.
The two men put their shoulders to the door, which soon yielded to their vigorous efforts, and they found themselves inside the shed, and in almost total darkness. By opening a shutter they admitted what daylight they could.
At first sight the wretched place seemed to be deserted; the little grate contained the ashes of a fire long since extinguished; all looked black and desolate. Another instant's investigation, however, revealed a bed in the extreme corner, and extended on the bed a human form.
"Dead!" sighed Servadac; "dead of cold and hunger!"Lieutenant Procope bent down and anxiously contemplated the body.
"No; he is alive!" he said, and drawing a small flask from his pocket he poured a few drops of brandy between the lips of the senseless man.
There was a faint sigh, followed by a feeble voice, which uttered the one word, "Gallia?""Yes, yes! Gallia!" echoed Servadac, eagerly.
"My comet, my comet!" said the voice, so low as to be almost inaudible, and the unfortunate man relapsed again into unconsciousness.
"Where have I seen this man?" thought Servadac to himself;"his face is strangely familiar to me."
But it was no time for deliberation. Not a moment was to be lost in getting the unconscious astronomer away from his desolate quarters.
He was soon conveyed to the yawl; his books, his scanty wardrobe, his papers, his instruments, and the blackboard which had served for his calculations, were quickly collected; the wind, by a fortuitous Providence, had shifted into a favorable quarter;they set their sail with all speed, and ere long were on their journey back from Formentera.
Thirty-six hours later, the brave travelers were greeted by the acclamations of their fellow-colonists, who had been most anxiously awaiting their reappearance, and the still senseless _savant_, who had neither opened his eyes nor spoken a word throughout the journey, was safely deposited in the warmth and security of the great hall of Nina's Hive.
