Just where the draw dipped down into the grassy park they drew rein an instant.  Faint and far a sound drifted to them.  Somebody down in the park had fired a rifle.

“I don’t agree with you, Phil,” the girl said, picking up the thread of their conversation where they had dropped it some minutes earlier.  “The nesters have as much right here as we have.  They come here to settle, and they take up government land.  Why shouldn’t they?”

“Because we got here first,” he retorted impatiently.  “Because our cattle and sheep have been feeding on the land they are fencing.  Because they close the water holes and the creeks and claim they are theirs.  It means the end of the open range.  That’s what it means.”

“Of course that’s what it means.  We’ll have to adapt ourselves to it.  You talk foolishness when you make threats to drive out the nesters.  That is the sort of thing Buck Weaver has been trying to do.  It’s absurd.  The law is back of them.  You would only come to trouble, and if you did succeed others would take their places.”

“And rustle our cattle,” he added sullenly.

“It isn’t proved they are the rustlers.  You haven’t a shred of evidence.  Perhaps they are, but you should prove it before you make the charge.”

“If they aren’t, who is?” he flared up.

“I don’t know.  But whoever it is will be caught and punished some day.  There is no doubt at all about that.”

“You talk a heap of foolishness, Phyl,” he answered resentfully.  “My notion is they never will be caught.  What makes you so sure they will?”

They had been riding down the draw, and at this moment Phyllis looked up, to see a rider silhouetted against the sky line on the ridge above.

“Oh, you Brill!” she cried, with a wave of her quirt.

The man turned, saw them, and rode slowly down.  He nodded, after the fashion of the range, first to the girl, and then to her brother.

“Morning,” he nodded.  “Headed for Mesa?  Here, too.”

He fell in with them and rode beside the girl.  Presently they topped a little hillock, and looked down into the park.  It had about the area of a mile, and was perhaps twice as long as broad.  Wooded spurs ran down from the hills into it here and there, and through the meadow leaped a silvery stream.

“Hello!  Wonder where that smoke comes from?”

It was Healy that spoke.  He pointed to a faint cloud rising from a distance.  Even before he began to speak, however, Phyllis had her field glasses out, and was adjusting them to her eyes.

“There’s a fire there and a man standing over it,” she presently announced.  “There’s something else there, too.  I can’t make it out—­something lying down.”

The men glanced at each other, and in the meeting of their eyes some intelligence passed between them.  It was as if the younger accused and the older sullenly denied.

“Lemme have the glasses,” Phil said to his sister almost roughly.
