they are I don't know. Plenty o' miners travel this trail at one time or another."
They looked at the distant horsemen for several minutes. Then the field-glasses were put away and they continued their journey.
Nightfall found them in a district that, to the boys, was desolation itself. Rocks were on every side, with little patches of the coarsest kind of growth, brushwood, stalk-like grass, and cacti. The air was so pure and thin that it fairly made one's nose tingle to breathe it.
All were tired out—indeed the boys were so stiff from the long ride that they could scarcely climb down from their saddles. But not for the world were they going to let Tom Dillon know this. They had told the old miner that they were used to roughing it and they wanted to "make good" in his eyes.
Some brushwood was gathered and a fire started, and the horses were tethered near by. The old miner knew where there was a spring of drinkable water—something occasionally hard to find in a district full of all sorts of minerals—and soon they had some boiling for coffee. Then their outfit was unstrapped, and they prepared supper and got ready to turn in for the night.
"I wonder if we can't see something of the campfire of Abe Blower, if he is ahead," remarked Dave.
