While there was nothing especially desirable in placing foot upon an iceberg, yet, boy-like, the two friends felt that it would be worth something to be able to say on their return home that they had actually stood upon one of them.
Inasmuch as the whole thing was a fool's errand in the eyes of Jack Cosgrove, he thought it was well to neglect nothing, so he shied the boat toward the gently sloping shelf, which came down to the water, and, with a couple of powerful sweeps of the oars, sent the bow far up the glassy surface, the stoppage being so gradual as to cause hardly a perceptible shock.
"Out with you, younkers, for the day will soon be gone," he called, waiting for the two to climb out before following them.
They lost no time in obeying, and he drew the boat so far up that he felt there was no fear of its being washed away during their absence. All took their guns, and, leaving it to the sailor to act as guide, they began picking their way up the incline, which continued for fully a dozen yards from the edge of the water.
"This is easy enough," remarked Rob; "if we only had our skates, we might – confound it!"
His feet shot up in the air, and down he came with a bump that shook off his hat, and would have sent him sliding to the boat had he not done some lively skirmishing to save himself. Fred laughed, as every boy does under similar circumstances, and he took particular heed to his own footsteps.
Jack had no purpose of venturing farther than to the top of the gentle incline, since there was no cause to do so; but, on reaching the point, he observed that it was easy to climb along a rougher portion to the right, and he led the way, the boys being more than willing to follow him.
They continued in this manner until they had gone a considerable distance, and, for the first time, the guide stopped and looked around. As he did so, he uttered an exclamation of amazement:
"Where have been my eyes?" he called out, as if unable to comprehend his oversight.
"What's the matter?" asked the boys, startled at his emotion, for which they saw no cause.
"There's one of the biggest storms ever heard of in these latitudes, bearing right down on us; it'll soon be night, and we shall be catched afore we reach the ship, lads! there isn't a minute to lose; it's all my fault."
He led the way at a reckless pace, the youths following as best they could, stumbling at times, but heeding it not as they scrambled to their feet and hurried after their friend, more frightened, if possible, than he.
He could out-travel them, and was at the bottom of the incline first. Before he reached it, he stopped short and uttered a despairing cry:
"No use, lads! the boat has been swept away!"
Such was the fact.
CHAPTER IV
ADRIFT
Jack Cosgrove, of the "Nautilus," was not often agitated by anything in which he became involved. Few of his perilous calling had gone through more thrilling experiences than he, and in them all he had acquired a reputation for coolness that could not be surpassed.
But one of the few occasions that stirred him to the heart was when hurrying to disembark from the iceberg, in the desperate hope of reaching the ship before the bursting of the gale and the closing of night, he found that the little boat had been swept from its fastenings, and the only means of escape was cut off.
There was more in the incident than occurred to Rob Carrol and Fred Warburton, who hastened after him. He had been in those latitudes before, and the reader will recall the story Captain McAlpine told to the boys of the time Jack was one of three who escaped from the collision of the whaling ship with an iceberg in the gloom of a dark night.
Had it been earlier in the day, and had no storm been impending, he could have afforded to laugh at this mishap, for at the most, it would have resulted in a temporary inconvenience only. The skipper would have discovered their plight sooner or later, and sent another boat to bring them off, but the present case was a hundred-fold more serious in every aspect.
In the first place, the fierce disturbance of the elements would compel Captain McAlpine to give all attention to the care of his ship. That was of more importance than the little party on the iceberg, who must be left to themselves for the time, since any effort to reach them would endanger the vessel, the loss of which meant the loss of everything, including the little company that found itself in sudden and dire peril.
What might take place during the storm and darkness his imagination shuddered to picture. Had the boat been found where he left it a short time before, desperate rowing would have carried them to the "Nautilus" in time to escape the full force of the storm. That was impossible now, and as to the future who could say?
The rowboat, as will be remembered, was simply drawn a short distance up the icy incline, where it ought to have remained until the return of the party. Such would have been the fact under ordinary circumstances, for the mighty bulk of the iceberg prevented it feeling the shock of any disturbance that could take place in its majestic sweep through the Arctic Ocean, except from its base striking the bottom of the sea, or a readjustment of its equilibrium, as they had observed in the case of the smaller berg. It might crush the "Great Eastern" if it lay in its path, but that would have been like a wagon passing over an egg-shell.
In leaving the boat as related, the stern lay in the water. Even then it would have been secure, but for the agitation caused by the coming gale. That began swaying the rear of the craft, whose support was so smooth that it speedily worked down the incline and floating into the open water instantly worked off beyond reach.
The boys knowing so little what all this meant and what was before them, were disposed to make light of their misfortune.
"By the great horned spoon, but that is bad!" exclaimed Jack, pointing out on the water, where the boat was seen bobbing on the rising waves, fully a hundred yards away, with the distance rapidly increasing.
It seems as if in the few minutes intervening, night had fully descended. The wind had risen to a gale, and, even at that short distance the little craft was fast growing indistinct in the gathering gloom.
"It isn't very pleasant," replied Rob, "but it might be worse."
"I should like to know how it could be worse," said the sailor, turning reprovingly toward him; "I wonder if I can do it."
The last words were uttered to himself, and he hastily laid down his gun on the ice by his side. Then he began taking off his outer coat.
"What do you mean to do?" asked the amazed Fred.
"I believe I can swim out to the boat and bring it back," was the reply, as he continued preparations.
"You musn't think of such a thing," protested Rob; "the water is cold enough to freeze you to death. If you can't reach it, you will have to come back to us, with your clothing frozen stiff, and nothing will save you from perishing."
"I'll chance that," said Jack, who, however, continued his preparations more deliberately, and with his eye still on the receding boat.
He was about to take the icy plunge, in the last effort to save himself and friends, when he stopped, and, straightening up, watched the craft for a few seconds.
"No," said he, "it can't be done; the thing is drifting faster than I can swim."
Such was the evident fact. While the vast mass of ice, as has been explained elsewhere, was under the impulse of a mighty under-current, the small craft was swept away by the surface current which flowed in the opposite direction.
Even while the party looked, the boat faded from sight in the gloom.
"I can't see it," said Rob, who, like the others, was peering intently into the darkness.
"Nor I either," added Fred.
"And what's more, you'll never see it again," commented Jack, who began slowly donning his outer garments; "younkers, I've been in a good many bad scraps in my life, and more than once would have sworn I was booked for Davy Jones' locker, but this is a little the worst of 'em all."
His young friends looked wonderingly at
