She and David raced down to the door, just as the bear turned to deal with this swift black shape that leaped round him in the snow, keeping just out of reach of his death-dealing forearm.

"Oh, the key, the key--it's locked!" cried Nell rather desperately. "Oh, Da! Where did Dad say----" She tried to think. David was absorbed in watching Robin's assault on the bear, which was sitting up again, making swift smacks at the illusive black attacker.

"Well done--go it, Robin!"

"Oh, don't, he'll be killed," Nell expostulated in an agonised voice, while her eyes travelled eagerly round the door frame, and she shook the solid latch.

"He won't be killed. He's too quick," said the boy triumphantly. "Key? Oh, there it is on a nail under the eave. I say, Nell, look at Rob! He's a right smart one!"

It was true. Rob was tormenting the bear with great cleverness, but Nell was far more intent on getting into safety, and probably few people have experienced a warmer sense of relief than she did when she opened the door of the bunk house.

Not much of a place, but the relief!

She glanced round with a satisfied look, and saw four bunks--like the berths of a ship--on one side, a rusty stove laid ready for lighting, as the custom is the outgoing traveller must lay the fire for the one who arrives wet and chilled, a pile of chopped wood, and a rough cupboard. Besides that a heavily made bench and a table. But the joy of it! Nell could have danced round that very rough table in spite of her weary legs, but there was Robin to capture and a furious bear outside.

After that look round she rushed out again and whistled to the dog. Then she called. Robin was very loath to leave the great black brute, out of whose reach he kept for the time being.

He came at Nell's call reluctantly. The bear came, too, but with more caution as he was not sure how much he liked the log house.
