Twilight was descending when two gaunt-eyed, hollow-cheeked lads, each with an arm thrown about the other's waist for support, were described, staggering across the Desert Maze. Behind then, at the end of a lariat, slouched a disconsolate, cowardly coyote.

A great shout went up from the camp of the Pony Riders.

They dashed out to meet their exhausted companions. Hoisting the two boys to their shoulders, they carried them triumphantly to camp.

Tom Parry, the guide, had been thrown by his pony stepping through a crust on the alkali, and had lain all night on the desert. Next day he had staggered back to camp, where he found his pony, and after a few hours' rest had taken up his fruitless search again.

Stacy's pony in the meantime had come in. The boys never knew how the animals got away, though from the fact that Tad's rifle was missing, it was believed that the hermit had ridden the pony off, turning it adrift later.

But the brave lads had found their way through the Desert Maze to camp, having passed through hardships and perils that would have daunted stronger and more experienced desert travelers.

Next morning the Pony Rider Boys struck their tents and broke camp. A few days later they crossed the line into California, where, after loading their stock and equipment into a large stock car, they started for the East.

Yet, though their summer vacation was rapidly drawing to a close, the Pony Rider Boys had not seen the end of their thrilling adventures. Another exciting trip lay before them; one which was destined to linger in memory for many years to come. The story of this, the end of the Silver Trail, will be related in a following volume entitled, "THE PONY RIDER BOYS IN NEW MEXICO."
