"Horses," suggested Hans.
"Sounds to me like cattle," said Dick. "But I don't see so much as a cow, do you?"
"Nothing whatever in sight," said Tom.
As the noise continued, Sam's horse began to grow skittish and showed some inclination to bolt.
"Steady, there!" sang out the youngest Rover. "None of that, now!" and he did his best to hold the steed in check.
"Something is coming!" cried Tom a few seconds later. "Something running pretty well, too!"
By instinct, all turned to the side of the trail, Sam taking a position between a clump of trees and a big rock. Swiftly the sound came closer, and then of a sudden a big and wild-looking steer broke into view, lumbering along the trail at his best speed.
"A steer!"
"Look out, fellows, he is wild and ugly!"
"He looks as if he meant to horn somebody!"
So the cries rang out, and all of the boys drew further to the side of the trail. As the steer came up, he paused and gazed at them in commingled wonder and anger.
"He is going to charge—" began Tom, when, with a fierce snort, the steer wheeled to one side and charged upon Sam and his horse at full speed!
