ers followed, but, though they could hear him still distinctly, they had to go a full mile before they came up to him. They found him standing on a little hill, on the top of which some enormous creature was moving about.
"We've got our wish for the asking," said the Doctor, loading his gun.
"Aye, it is a bear, and no mistake, and a jolly big one, too," said Bell, imitating the Doctor's example.
"I don't know, it is a strange sort of bear," added Johnson, preparing to fire after his companions.
Duk was barking furiously. Bell advanced within twenty feet and fired; but the ball took no effect.
Johnson's turn came last, but his ball was powerless like the others.
"I see how it is!" exclaimed the Doctor; "it is that confounded refraction again, one never gets used to it. Why, that bear is more than a thousand paces off."
"Let us go nearer then," replied Bell.
Away rushed all three towards the animal, who did not appear the least disturbed by their shots.
As soon as they were at the right distance they fired again, and the bear gave one tremendous spring and fell at the foot of the hill mortally wounded, there was no doubt.
Duk rushed upon him tooth and nail, holding him fast till the hunters came up.
"Well, it hasn't been much trouble to kill that bear, anyhow," said the Doctor.
"Three shots and he is done for," exclaimed Bell, contemptuously.
"It is very strange!" said Johnson.
"Unless we have chanced to come just at the very moment he was dying of old age," suggested the Doctor, laughing.
"My word, it is little matter whether he is young or old. It is a lucky prize for us."
But what was their blank amazement on reaching their victim to find that it was a white fox instead of a bear!
"Well, I declare," said Bell, "if that's not too bad!"
"Yes, I think so," replied the Doctor. "To kill a bear, and then pick up a fox."
Johnson stood stupefied, not knowing what to say.
At last the Doctor burst out laughing again, and said:
"It is just the refraction, that everlasting refraction!"
