"There," he remarked, finally, throwing down the flap as though satisfied with his work. "I reckon I've got it fixed now so that it will hold through the day; but I need a new girth, and when we pull up again at Circle Ranch I'll see about getting it. Oh! did you make out anything with the glasses, Frank?"

He sprang into the saddle like one who had spent much of his time on horseback. Domino curvetted and pranced a little, being still full of mettle and spirits; but a very firm hand held him in.

"Take the glass, and see if you can make out what it is," Frank remarked, as if he hardly knew himself, or felt like trusting his eyes.

A minute later Bob lowered the glasses.

"There's something on the ground, and I can catch a glimpse of what looks like a dun-colored hide through the tufts of buffalo grass. The yearling was red, you said, Frank? All right. Then I reckon we'll find her there; but not on her feet."

"Come on!"

As he said these curt words Frank let Buckskin have his head; and, accompanied by his chum, started at a full gallop over the level, in the direction of the spot where the dun-colored object had been sighted.

Shortly afterward they topped a little rise, and pulled up. No need to doubt their eyes now. Just before them lay the mangled remains of the lame yearling, very little being left to tell the story of how the animal had met its fate.

"Wolves!" said Frank, gloomily, as he sat looking down at the torn hide.

"I don't know the signs as well as you, Frank, but I'd say the same from general indications. And they had a royal good feast, too. This makes a round half dozen head your father has lost in the last month, doesn't it?" asked Bob.
