This was their business--to harass and torment, to retard flight, to stop their prey again and again until their masters came to finish the kill.

It was a quite fair and thrilling sport for the bear and the dogs.

The man who comes up with the rifle ends it in murder.
But if the dogs had their tricks, Thor also had his.

After three or four vain rushes, in which the Airedales eluded him by their superior quickness, he backed slowly toward the huge rock beside which Muskwa was crouching, and as he retreated the dogs advanced.
Their increased barking and Thor's evident inability to drive them away or tear them to pieces terrified Muskwa more than ever.

Suddenly he turned tail and darted into a crevice in the rock behind him.
Thor continued to back until his great hips touched the stone.
