"The bear 'll kill him!" "Oh, that would be dreadful!" replied Helen, in distress.

"But what on earth can we do ?" "HEL-LO, DALE!" called Bo, at the highest pitch of her piercing voice.
No answer came.

A heavy crash of brush, a rolling of stones, another growl from the slope told Helen that the hound had brought the bear to bay.
"Nell, I'm going up," said Bo, deliberately.
"No-no! Are you mad ?" returned Helen.
"The bear will kill Pedro." "He might kill you." "You ride that way and yell for Dale," rejoined Bo.
"What will--you do ?" gasped Helen.
"I'll shoot at the bear--scare him off.

If he chases me he can't catch me coming downhill.

Dale said that." "You're crazy!" cried Helen, as Bo looked up the slope, searching for open ground.
