"I see quite a cloud of dust to the northward." "How far off ?" asked Dave.
"About a mile, I should say, and it's headed this way, coming closer every minute." "What's behind the cloud?

"I'm trying to see," Dick replied.

"There, I got a glimpse then.
It's some kind of animals, heading for this camp at a gallop." "It can't be cavalry," shouted Reade.

"You don't see any men, do you ?" "No," Prescott called down, shielding his eyes with one hand.
"Say, fellows!" "Have you guessed what it is ?" demanded Harry Hazelton.
"I know what it is---now!" Dick answered.

"Careful, there!" shouted Tom Reade.

"That isn't a low baluster you're sliding down." "Keep quiet, until I reach the ground," gasped Dick.
