"How did that help you?"

"Why, I just happened to recollect a fact related by Captain Ross in his voyages. He states that they pierced a plank, an inch thick, with a bullet made of mercury. Oil would even have suited my purpose, for, he adds, that a ball of frozen almond oil splits through a post without breaking in pieces."

"It is quite incredible!"

"But it is a fact, Johnson. Well, come now, this bit of metal may save our lives. We'll leave it exposed to the air a little while, and go and have a look for the bear."

Just then Hatteras made his appearance, and the

Doctor told him his project, and showed him the mercury.

The captain grasped his hand silently, and the three hunters went off in quest of their game.

[Ill.u.s.tration: ]

The weather was very clear, and Hatteras, who was a little ahead of the others, speedily discovered the bear about three hundred yards distant, sitting on his hind quarters sniffing the air, evidently scenting the intruders on his domains.

"There he is!" he exclaimed.

"Hush!" cried the Doctor.

But the enormous quadruped, even when he perceived his antagonists, never stirred, and displayed neither fear nor anger. It would not be easy to get near him, however, and Hatteras said--

"Friends, this is no idle sport, our very existence is at stake; we must act prudently."

"Yes," replied the Doctor, "for we have but the one shot to depend upon. We must not miss, for if Away they went, while the old boatswain slipped behind a hummock, which completely hid him from the bear, who continued still in the same place and in the same position.

CHAPTER V.

THE SEAL AND THE BEAR.

"You know, Doctor," said Hatteras, as they returned to the hut, "the polar bears subsist almost entirely on seals. They'll lie in wait for them beside the creva.s.ses for whole days, ready to strangle them the moment their heads appear above the surface. It is not likely, then, that a bear will be frightened of a seal."

"I think I see what you are after, but it is dangerous."

"Yes, but there is more chance of success than in trying any other plan, so I mean to risk it. I am going to dress myself in the seal's skin, and creep along the ice. Come, don't let us lose time. Load the gun and give it me."

The Doctor could not say anything, for he would have done the same himself, so he followed Hatteras silently to the sledge, taking with him a couple of hatchets for his own and Johnson's use.

Hatteras soon made his toilette, and slipped into the skin, which was big enough to cover him almost entirely.

"Now, then, give me the gun," he said, "and you be off to Johnson. I must try and steal a march on my adversary."

"Courage, Hatteras!" said the Doctor, handing him the weapon, which he had carefully loaded meanwhile.

"Never fear! but be sure you don't show yourselves till I fire."

The Doctor soon joined the old boatswain behind the hummock, and told him what they had been doing. The bear was still there, but moving restlessly about, as if he felt the approach of danger.

In a quarter of an hour or so the seal made his appearance on the ice. He had gone a good way round, so as to come on the bear by surprise, and every movement was so perfect an imitation of a seal, that even the Doctor would have been deceived if he had not known it was Hatteras.

"It is capital!" said Johnson, in a low voice. The bear had instantly caught sight of the supposed seal, for he gathered himself up, preparing to make a spring as the animal came nearer, apparently seeking to return to his native element, and unaware of the enemy's proximity. Bruin went to work with extreme prudence, though his eyes glared with greedy desire to clutch the coveted prey, for he had probably been fasting a month, if not two. He allowed his victim to get within ten paces of him, and then sprang forward with a tremendous bound, but stopped short, stupefied and frightened, within three steps of Hatteras, who started up that moment, and, throwing off his disguise, knelt on one knee, and aimed straight at the bear's heart. He fired, and the huge monster rolled back on the ice.

[Ill.u.s.tration: ]

"Forward! Forward!" shouted the Doctor, hurrying towards Hatteras, for the bear had reared on his hind legs, and was striking the air with one paw and tearing up the snow to stanch his wound with the other.

Hatteras never moved, but waited, knife in hand. He had aimed well, and fired with a sure and steady aim. Before either of his companions came up he had plunged the knife in the animal's throat, and made an end of him, for he fell down at once to rise no more.

"Hurrah! Bravo!" shouted Johnson and the Doctor, but Hatteras was as cool and unexcited as possible, and stood with folded arms gazing at his prostrate foe.

"It is my turn now," said Johnson. "It is a good thing the bear is killed, but if we leave him out here much longer, he will get as hard as a stone, and we shall be able to do nothing with him."

He began forthwith to strip the skin off, and a fine business it was, for the enormous quadruped was almost as large as an ox. It measured nearly nine feet long, and four round, and the great tusks in his jaws were three inches long.

On cutting the carcase open, Johnson found nothing but water in the stomach. The beast had evidently had no food for a long time, yet it was very fat, and weighed fifteen hundred pounds. The hunters were so famished that they had hardly patience to carry home the flesh to be cooked, and it needed all the Doctor's persuasion to prevent them eating it raw.

On entering the hut, each man with a load on his back, Clawbonny was struck with the coldness that pervaded the atmosphere. On going up to the stove he found the fire black out. The exciting business of the morning had made Johnson neglect his accustomed duty of replenishing the stove.

The Doctor tried to blow the embers into a flame, but finding he could not even get a red spark, he went out to the sledge to fetch tinder, and get the steel from Johnson.

The old sailor put his hand into his pocket, but was surprised to find the steel missing. He felt in the other pockets, but it was not there. Then he went into the hut again, and shook the blanket he had slept in all night, but his search was still unsuccessful.

He went back to his companions and said--

"Are you sure, Doctor, you haven't the steel?"

"Quite, Johnson."

"And you haven't it either, captain?"

"Not I!" replied Hatteras.

"It has always been in your keeping," said the Doctor.

"Well, I have not got it now!" exclaimed Johnson, turning pale.

"Not got the steel!" repeated the Doctor, shuddering involuntarily at the bare idea of its loss, for it was all the means they had of procuring a fire.

"Look again, Johnson," he said.

The boatswain hurried to the only remaining place he could think of, the hummock where he had stood to watch the bear. But the missing treasure was nowhere to be found, and the old sailor returned in despair.

Hatteras looked at him, but no word of reproach escaped his lips. He only said--
