“And say, whatever’s doing, don’t you dare forget to count me in,” piped up Billie, who was immediately afraid lest they might set out to arrange plans that would leave him in the lurch, perhaps to ’tend camp while they rode off; and he was determined to rebel against such an ignominious discard.

“Sure they must have been, Billie, and that remark shows that you’ve got your wits about you!” declared Donald; and then turning again to the third member of the little group he went on: “if you mean it, Ad, and say the word, why we’ll pull out of these diggings in a rush, and chase after the herd.”

“It wouldn’t be very long before we’d hear the rumble again, if we kept right on the way they were heading when they passed here,” observed Adrian, thoughtfully.

“That’s right,” Donald assured him.
