"No see us," said Two Arrows. "Come! Heap bad."

So it was, for the dreaded strangers were between them and the mountains. For all they knew, they might have ridden past others unseen, and these might intercept their return. Sile was only a white boy, and in an instant he understood that the young chief was the "captain" of their squad of two.

Two Arrows seemed to have the same notion instinctively, for anybody could read the look of blank uncertainty upon Sile's face. His binocular spy-glass could help him see farther and more accurately than the best pair of Indian eyes in the world, but it could not tell him what to do next.

"Come!" said Two Arrows, as he led his pony back down the slope and towards the forest that skirted the river. This was less than half a mile away, but the horses were not mounted until both were well under cover of it. It struck Sile that they might safely ride homeward along the stream, but Nez Percé training and caution forbade any such risk as that. Even the operation of reaching the bank might be full of peril, for nobody could guess at what moment they might stumble upon Apache warriors, and no others were at all likely to be there. It was most unlikely, however, that their enemies were advancing upon both sides of the water, and as soon as Two Arrows reached it he rode in. It was a wide and therefore shallow place, easily forded, and Sile breathed more freely as soon as he was under the shade of the woods beyond. His guide and captain pushed right on until they were out in a comparatively open reach of country, and then he turned to Sile, his whole face gleaming with uncontrollable excitement, and exclaimed,

"Ugh! Ride now. Kill hoss. Save pale-face. Save Nez Percé. Get there before Apache. All scalp gone if 'Pache come first."

He suppressed a whoop, but the next bound of his pony explained his meaning, and Sile galloped, stride by stride, with him. It was a race for life and for the lives of many others; for Two Arrows had briefly read that problem when he said to Sile, as he handed him back his glass,

"No squaw. Braves on war-path. No hunt. Kill. Take scalp."

Both were well mounted, and Sile rode well, although by no means so completely at home on horseback as was his red friend. His rifle, too, was more tiresome to carry than was a light lance, and the bow and arrows were now tightly "slung," and required no handling. It would not do to wear out their horses in one rush, but they kept on at the highest speed at all consistent with a long ride. It was much faster, at all events, than the Apaches were likely to travel, unless something new should stir them up. By keeping well away from the stream, they were not compelled to follow its windings, and could ride more nearly in a straight line, only turning out for clumps of trees and similar obstructions and paying no attention to game, although they now saw gang after gang of deer and a respectable party of bisons.
