"Why, what do you mean?"

"I happened to remember something Captain Ross related in the account of his voyage: he said he shot through an inch plank with a bullet of frozen mercury; if I had any oil it would amount to nearly the same thing, for he speaks of a ball of sweet almond, which was fired against a post and fell back to the ground unbroken."

"That is hardly credible!"

"But it is true, Johnson; this piece of metal may save our lives; let us leave it here in the air before we take it, and go and see whether the bear is still following us."

At that moment Hatteras came out of the hut; the doctor showed him the bullet, and told him what he thought of doing; the captain pressed his hand, and the three went off to inspect. The air was very clear. Hatteras, who was ahead of his companions, discovered the bear about a half-mile off. The animal, seated on his hind quarters, was busily moving his head about, sniffing towards these new arrivals.

"There he is!" shouted the captain.

"Silence!" said the doctor.

But the huge beast did not stir when he saw the hunters. He gazed at them without fear or anger. Still, it would be found hard to approach him.

"My friends," said Hatteras, "we have not come out for sport, but to save our lives. Let us act cautiously."
