"They'll go with us, of course. We can't leave them here. We must head for Ceralvo's at once. How could those Indians have got over that way?"

"It is beyond me to say, sir. I didn't know they ever went west of the Santa Maria."

"I can hardly believe it now, but there's no doubting that signal; it is to call us thither at all speed wherever we may be, and means only one thing,—'Apaches here.' Sergeant Wing is not the man to get stampeded. Can they have jumped the stage, do you think, or attacked some of Ceralvo's people?"

"Lord knows, sir. I don't see how they could have swung around there; there's nothing to tempt them along that range until they get to the pass itself. They must have come around south of Moreno's."

"I think not, sergeant."

The words were spoken in a very quiet voice. Drummond turned in surprise, his foot in the stirrup, and looked at the speaker, a keen-eyed trooper of middle age, whose hair was already sprinkled with gray.

"Why not, Bland?"

"Because we have been along the range for nearly fifty miles below here, sir, and haven't crossed a sign, and because I understand now what I couldn't account for at two o'clock,—what I thought must be imagination."

"What was that?"

"Smoke, sir, off towards the Gila, north of Ceralvo's, I should say, just about north of west of where we are."
