s elapsed before she reappeared transformed. It
was a slim youth garbed as a cowpuncher that now slipped along the passage
to the rear, softly opened the door of the cook's room, noiselessly
abstracted the key, closed the door again as gently, and locked it from
the outside. She ran into her own room, strapped on her revolver belt, and
took her empty rifle from its case. As she ran through the room below the
one Jim occupied, she caught sight of a black rag thrown carelessly into
the fireplace and stuffed it into her pocket.

"That's just like Dad to leave evidence lying around," she said to
herself, for even in the anxiety that was flooding her she kept her quiet
commonsense.

After searching the horizon carefully to see that nobody was in sight,
she got into the rig and drove round the corral to the irrigating ditch.
This was a wide lateral of the main canal, used to supply the whole lower
valley with water, and just now it was empty. Melissy drove down into its
sandy bed and followed its course as rapidly as she could. If she were
only in time! If the stage had not yet passed! That was her only fear, the

She had learned to imitate the long roll of the vaquero's stride, the
mannerisms common to his class, and even the heavy voice of a man. More
than once she had passed muster as a young man in the shapeless garments
she was now wearing. She felt confident that the very audacity of the
thing would carry it off. There would be a guard for the treasure box, of
course, but if all worked well he could be taken by surprise. Her rifle
was not loaded, but the chances were a hundred to one that she would not
need to use it.

For the first time in his life the roan got the whip from his mistress.

"Git up, Bob. We've got to hurry. It's for dad," she cried, as they raced
through the sand and sent it flying from the wheels.

The Fort Allison stage passed within thr
