Williams and the other men had been gone for something more than an hour.  But, as Owen had said, they would travel slowly, having no incentive for haste.  Sanderson, on the other hand, would make Streak run his best—­and she knew Streak could run.

So she began to estimate the time that would elapse before Sanderson and Williams returned.  With an hour’s start, she gave Sanderson three-quarters of an hour to catch them.  Then, three quarters of an hour additional would be required for the run home—­if they came back as swiftly as Sanderson had gone.

But she doubted that.  She would give them a full hour for the return trip.  That would make an hour and three quarters.

But it seemed to her that an age elapsed before the minute hand on the clock dragged itself one-quarter of the distance around the circle.

She looked out at Dale and his men.  The men were all standing, their backs to the house.  But it seemed to the girl that they were standing nearer to one another than they had been all along, and a pulse of trepidation ran over her.

Watching them closely, Mary felt they were meditating some action.  They were whispering to one another, and Dale was gesturing as emphatically as he could.

The girl was certain they contemplated concerted action of some sort, and she was just about to apprise Owen of her fears, when she saw one of the men—­and then another and another—­working with the ropes that bound them.  One of the men turned, a huge grin on his face.  She caught the flash of metal in the man’s hands, saw the rope fall from them, severed.

She shouted, then, at Owen: 

“Look out, Barney; they’ve got a knife!”

At the instant she spoke the men moved as though by prearrangement.  By the time her voice reached Owen’s ears the men had scattered, running in all directions.  Several ran directly away from the house, others toward it, some went toward the corners of the building nearest them.  All were running zigzag fashion.

Owen, his eyes blazing, fired three times in rapid succession.  One of the men tumbled, headlong, turning over several times and landing face downward on the sand of the yard; but several others, apparently uninjured, ran straight for the ranchhouse.

There were no stationary targets for Owen to shoot at.  By the time he had fired the three shots the men were all moving.  Several the girl saw as they ran around the ranchhouse; three or four others ran straight for the door in which she stood.

She cried sharply to Owen, and the latter fired once, as three or four figures crossed the porch.  The girl could not tell whether or not Dale was one of the three, for the men moved quickly.

Owen missed; Mary heard him curse.  And before he had time to do either again the men were inside.  Mary was standing near Owen, and she had reached down for one of the pistols that lay on the floor.
