"I wish we could yell and warn them!" exclaimed Eleanor, half-rising from her seat.

"They'll never hear us at this distance, but we might run along the top-trail and beckon them to climb up there."

"But, Polly, by the time we reach the shale they will be almost at the Rainbow Cliffs," objected Eleanor.

"Yes, I know, but it seems awful to sit here and watch them ride over that dangerous road."

"To relieve our minds, we can go down as far as possible and meet them when they ride out at Rainbow Cliffs," suggested Eleanor.

So the two girls scrambled down from their high point of observation, and started along the rock-ribbed road that led past the Cliffs. They had not gone far along this trail, however, before Polly saw Jeb riding down from the corrals.

"If I could only get Jeb's attention, he could ride fast and warn those men of their danger," Polly said, thinking aloud.

"Let's both scream at the top of our lungs and see if he can hear us."

So the two girls stood out on the edge of a huge bowlder and, making megaphones of their hands, shouted again and again. The depression made by the crater that lay between the Cliffs and the corral, acted as a hollow tube, so Jeb finally wheeled around and tried to locate the call. When he saw the girls, he immediately started to meet them as no one on the ranch would shout that way for fun.

It took ten minutes for Jeb to cover the circuitous path and join the girls, and when they had hastily explained the cause of their concern, he replied: "Gosh! Ah was told to hang a sign on that flat cliff to warn folks offen the bad trail!"
