He climbed, and climbed; and presently he heard as it were in the air a voice say, "Go out on the bough!" He looked, and there was a long massive branch before him shooting upwards at a slight angle: he threw his body across it, and by a series of convulsive efforts worked up it to the end.
Then he looked round panting.
The bear was mounting the tree on the other side.

He heard her claws scrape, and saw her bulge on both sides of the massive tree.

Her eye not being very quick, she reached the fork and passed it, mounting the main stem.

Gerard drew breath more freely.

The bear either heard him, or found by scent she was wrong: she paused; presently she caught sight of him.
