"Keep still, some one's coming."
The lad's keen ears had caught a sound which Stacy had entirely failed to hear. It was the sound of horses making their way through the bushes. There were several in the party, Tad could tell by the sounds, and having in mind the man Lasar, he thought he might perhaps learn something of advantage by remaining quietly on the top of the rock.

"I wonder who they are?" questioned Tad.
"They look savage. I wonder if they'd hurt us, Tad?"
