"Hear 'em shouting now! What are they up to?"
"Making a last rush to overtake us, while we're yet in the plain. But it is too late, my gay scalp hunters!"
The mountains were now drawing near very fast, and with the heavy forest along their slopes they seemed to Will to come forward of themselves to welcome them. He became suddenly aware that his body ached from the long gallop, and that the dust raised by the beating hoofs was caked thickly on his face. His lips were dry and burning, and he longed for water.
"In five more minutes we'll be on the first slope," said Boyd, "and as we'll soon be hidden in the forest I think I'll say farewell to our pursuers."
"I don't understand you, Jim."
"I'm going to say only one word, and it'll be short and sharp."
He turned suddenly in his saddle, raised the repeating rifle and fired once at the band.
He had elevated the sight for a very long shot, regarding it as a mere chance, but the bullet struck a pony and a few moments of confusion in the band followed. Now Boyd and young Clarke made their horses use the reserves of strength they had saved so prudently, and with a fine spurt soon gained the shelter of the woods, in which they disappeared from the sight of the pursuing horde.
They found themselves among oaks, aspens, pines, cedars, and birch, and they rode on a turf that was thick, soft and springy. But Selim neighed his approval and Boyd pulled down to a walk. A little farther on both dismounted at his suggestion.
"It'll limber us up and at the same time help the horses," he said. "Knowing what kind of rifles we carry and how we can shoot, the Sioux won't be in any hurry to ride into the forest directly after us. We've a big advantage now in being able to see without being seen. As we needn't hurry, suppose we stop and take another look with those glasses of yours, Will. I never thought they'd prove so useful when you insisted on bringing 'em."
