"Then, if we do as well this afternoon, we'll be forty miles from the ranch by the time we camp to-night."
"We'll not make over ten or twelve miles this afternoon, lad," was the answer. "It will be hard climbing up the hills."
"But harder climbing to-morrow," put in Dave.

As soon as they left the spring, the youths realized what was before them. The trail now led constantly upward, and was in parts stony and uncertain. In several places they had to leap brooks of fair size.
"This isn't so nice," remarked Phil, as they came to a halt, to allow the horses to rest after a particularly difficult hill had been climbed.
"Oh, this is nothing to the traveling we'll do tomorrow," answered Sid Todd. "We are only in the foothills now—to-morrow we'll be right in the mountains."
About four o'clock they gained the top of another hill. As they came out in a cleared spot all gazed around with interest.
