"To-morrow I may see my father!" said Jack in a low tone.

Hardly had he spoken the words when there was a noise behind them, and the boys turned to see two horsemen riding up.

At first the chums did not attach much significance to the appearance of the two riders. The men were coming on as fast as their horses could travel, but the boys thought they were ranchmen or herdsmen.

"The two first ones! They're the ones we want!" exclaimed the foremost of the men, and at that Nat and Jack, who were in front of John, started. "Grab one Nate, and I'll tackle the other!"

Before Nat and Jack could make a move to defend themselves they found a rope circling their arms just above their elbows. The men had cast their lariats and pinioned the boys. The resulting jerk nearly pulled them from their horses, but when the men saw this, they urged their steeds close to their captives, and held them in their saddle, while they deftly bound their hands.

There was a clatter of hoofs at which Jack and Nat turned their heads. If they expected to see some one coming to rescue them they were disappointed, for all they beheld was John, swinging his horse around on the trail and making off at top speed.

"Come back!" yelled one of the men, making a move as if to reach for his gun, but at this Jack wiggled so he had to give all his attention to the captive youth.

"I'll come back—" yelled John, and the rest of what he said was lost in the clatter his horse made as it sprang over stones. Then John disappeared around a big ledge of rock.

"Never mind," said one of the men, whom his companion had addressed as Nate. "We don't need him."

"Guess not, Sid," was the reply. "We've got the main ones. He don't count."
