He should have started three hours earlier. Chapman ranch was only
eighteen miles away, but there was a road for only three miles of the
distance. He had ridden over there once with one of the Half-Moon
cowpunchers, and he had the direction well-defined in his mind.

Sam turned off the old Government road at the split mesquite, and
struck down the arroyo of the Quintanilla. Here was a narrow stretch
of smiling valley, upholstered with a rich mat of green, curly
mesquite grass; and Mexico consumed those few miles quickly with his
long, easy lope. Again, upon reaching Wild Duck Waterhole, must he
abandon well-defined ways. He turned now to his right up a little
hill, pebble-covered, upon which grew only the tenacious and thorny
prickly pear and chaparral. At the summit of this he paused to take
his last general view of the landscape for, from now on, he must wind
through brakes and thickets of chaparral, pear, and mesquite, for the
most part seeing scarcely farther than twenty yards in any direction,
choosing his way by the prairie-dweller's instinct, guided only by an
occasional glimpse of a far distant hilltop, a peculiarly shaped knot
of trees, or the position of the sun.

Sam rode down the sloping hill and plunged into the great pear flat

In about two hours he discovered that he was lost. Then came the

tortuous labyrinths of the jungle. At the moment his master's
sureness of the route had failed his horse had divined the fact.
There were no hills now that they could climb to obtain a view of
the country. They came upon a few, but so dense and interlaced was
