"He is dragging Elfreda.

Don't shoot!" Grace's eyes by this time had become adjusted to the uncertain light and her mind instantly comprehended the situation, so far as the fact that her companion was being dragged was concerned, though she did not realize that it was her rope that was around the neck of the frightened animal.
Young Bruin went through Grace's tent, Elfreda following him like a projectile.

Both emerged from the ruins on the other side and headed for the bush, with the Overland Riders in full pursuit.
"Throw yourself on the rope and grab it!" panted Grace, as Hippy ran past her.
"Let go!" he shouted to Miss Briggs, but, though Elfreda was willing to do so, she could not.

Neither could she summon enough breath to answer.
"Snub the rope around something," urged Grace.
Hippy reached and passed Elfreda and threw himself on the rope, as he thought.

The bear, having made a sudden turn to get away from him, caused Hippy to miss the rope by a few feet.
