All passed to the locality indicated, and each youth looked at the hoofmarks with interest. They were made by a number of horses, probably six or eight, and though the marks were washed a little, as if by rain, they could still be plainly seen.
"Do you think they were made by the horses that were stolen, Dave?" questioned Phil.
"I don't know what to think."
"The horse-thieves might easily have come this way," said the senator's son. "They would be more apt to go away from the ranch than towards it."
"Maybe they stopped here during the big blow," said Phil.
"I think you are right, for here are marks where the animals were tied to trees," went on Dave. "I wonder—well, I declare!"
Dave stopped short and picked up a bit of a leather halter lying on the ground. It was of curious Mexican design, having a light leather thong entwined in a dark one.
"I don't know that I have ever seen a halter like that before," mused Roger, as he took the bit of halter from Dave, and then passed it to Phil.
"I have," answered Dave.
"So have I!" cried the shipowner's son. "Link Merwell's horse had one on, the day we met on the trail!"
