The puppy, licking at Doby's bitten hand, begged ferociously to be allowed to get out and get at her.

His father gave his animals to the care of another and took the boy's watch at the wagon's end in the last of the train. Doby, who could not sleep on account of his pet's restlessness, sat beside his father through the long hours of that fearsome night.

In the darkest time, just before the dawn, when deep sleep had finally settled upon the train, the puppy leaped up and slipped its leash and called in sharp glad barks. Without, under the doubly guarded wagon, the she-wolf crooned. The puppy capered with joy. Softly the coaxing whine was repeated. The puppy answered in baby staccato.

And then they knew! Even Doby knew! Knew whence the puppy came, why it was so fierce, and why the lone wolf stalked the train!

A dozen rifles cracked, but the "unerring" pioneer marksmen could not hit that sly wolf in the darkness. She was out of range again.

The father and son looked at each other in consternation.

There was only one thing to do. Poor Doby did it.

He spoke a word to the guards. Then with his heart-strings quite torn apart he took the beloved and unloving wolf whelp from the wagon, set it upon the ground, and watched it lope away into the waiting dark.

Because a wolf never returns to an uncovered trap, the siege was raised.

When affairs are at their worst a brave spirit struggles hardest. So daylight found Doby cheerfully holding a court of speculating emigrants, who were bent on discussing their late guest, the wolf whelp.
