"Oh yes," said Nell; "he's in a bad temper. What a nuisance!"
"Can't we shoot him?" suggested David, as they moved on with increasing speed.
"Shoot! My dear boy, with automatics! He wouldn't mind much unless we shot his eye out, and then he'd be deadly! Wish I'd brought the little rifle, but I thought it was safer with the pelts on the sled, it's so heavy to carry. You want something pretty strong to stop a bear. Dad says their skins are so thick. Bother it, he's coming. Run, Da, and don't tumble over the roots, whatever you do. Remember the bunk house is good and close. We'll get there."
"Where's that donkey Robin?" muttered David, but Nell did not answer; she was intent on this very tiresome adventure. It was fairly plain that the dog had found the bear trail and followed it to the cave. No doubt he was hunting up there among the rocks, and in a way she was not anxious for him to come till this was over, because a dog has small chance with a bear if it comes to fighting at close quarters. People have an idea that a bear kills by hugging, and will always squeeze his enemy to death, whereas the astonishing weapon it uses is the lightning swiftness of its strike. A bear strikes with his fore-paw--which is armed with terrible rending claw--as quickly as a snake darts, and he can break the neck of a moose or a buffalo with one smack. Nell knew all about this and she did not want Robin to come to close quarters, therefore she would not whistle, but ran on, David keeping up with her, faster and faster.
Now these two were very swift of foot, but they had been greatly tried for a good many days and nights, they were hungry and a bit spent, for it was afternoon; lastly, they were cumbered with their packs and shoes. They were handicapped, but fortunately for them so also was the bear, for he, too, was not at his best.
A certain great writer says that an elephant does not seem to be made for speed, but if he wanted to catch an express train he would probably catch it. A bear, too, does not look as though he could run, but he can, very fast indeed, and it took all the running those two could manage to keep ahead. Nell's anxiety was David chiefly. Could he hold out?
Fortunately it was all downhill, and they were very surefooted with long practice of running over rough ground. The bear came shambling on behind, grunting with anger.
"Don't look round, Da," ordered Nell sharply, "you'll trip up! Look where you're going! The bunk house is quite close now."
David did as he was told, knowing she was right about the tripping. A stumble would be death. Just where you put your feet mattered enormously at that moment. The bunk house was close--which was comforting.
What he did not realise, and Nell wanted to keep from him, was that the bear was gaining. Every time she sent a glancing look over her shoulder he was a little nearer. She measured the distance to the bunk house anxiously. It was touch and go; she would not admit to herself that it could not be done. What was the distance? Fifty yards, forty? Less?
