Like a snake it writhed in the air, and then settled just before the leaping antelope. The creature put its forelegs and head fairly into the whirring circle!

The moment before–figuring with a nicety that made Pratt Sanderson gasp with wonder–Frances had pulled back on Molly’s bit and jerked back her own arm that controlled the lasso.

Molly slid on her haunches, while the loop tightened and held the antelope in an unbreakable grip.

“Quick, Pratt!” cried the girl of the ranges, seeing the young man coming up. “Get down and use your knife. He’ll kick free in a second.”

As Pratt obeyed, leaping from his saddle before the grey pony really halted, Sue Latrop raced up on her mount and stopped. Frances was leaning back in her saddle, holding the rope as taut as possible. Pratt flung himself upon the struggling antelope.

And then rather a strange and unexpected thing happened. Pratt had the panting, quivering, frightened creature in his arms. A thrust of his hunting knife would have put it out of all pain.

Sue was as eager as one of the hounds which were now coming up with great leaps. Pratt glanced around a moment, saw the dogs coming, and suddenly loosened the noose and let the antelope go free.

“What are you doing?” shrieked the girl from Boston. “You’ve let it go!”

“Yes,” said Pratt, quietly.

“But what for?” demanded Sue, quite angrily. “Why! you had it.”
