They blew up the mattress to its fullest extent and launched it. Piling on it the things they felt absolutely necessary to take with them, they were overjoyed to find the improvised raft equal to the task. The rest of the truck had to be abandoned.

“Well, might as well start, I reckon,” said Bob. “This is the first time I’ve ever gone in for an all-day swim. We won’t really need a bath the rest of the summer after this.” Jerry laughed a reply.

It didn’t turn out to be so bad as they had imagined. Shortly after they started the river grew smoother and shallower, so that wading was quite possible. During the afternoon of the next day, with almost startling suddenness they found themselves out of the canyon. It ended almost as surprisingly as it had begun. A sudden bend through the high cliffs and they were in the open country.

Bob turned to Jerry and shook his hand. “We’ve done it, old boy. We’ve beaten the Labyrinth.”

In the midst of their mutual congratulations a hail came to them from the bank. Surprised, they looked up to see a figure waving to them. They pulled ashore and found a grizzled old man standing up beside a camp fire.

“Did ye come through the gap?” was his greeting in a mild, unsurprised tone.

The boys answered in the affirmative. The old man nodded his head. “Pretty good, pretty good. You sho’ surprised me. Only ones what I’ve seen come through before have been dead ones. Sit ’round and in a minute I’ll have something to eat for ye.”

Jerry recognized the type at once. It was a desert rat, one of those old men who, lured by the dream of gold, haunt the desert, usually alone. Years pass over their heads in the search which never ends. At last the gold mine that they will find some day becomes merely the excuse not the aim of the unending pilgrimage. The desert, the loneliness is claiming them. If they found a mine worth the developing, probably they would sell it and blow in the proceeds and be off again as soon as possible. They have been too long away from civilization for anything to surprise them. The desert is mysterious, the loneliness makes everything possible.

The old man’s meal was sour dough biscuits and a sort of soup made from jerked beef and river water. But he offered it to them and served it as if it were a banquet. To the tired, hungry boys it was a banquet. They had done tremendous deeds on a diet of canned goods and any change was welcome.

The old man ventured no further curiosity in what they had done. They had come through the Labyrinth, he had accepted the fact, and that was all there was to it. He spoke very little and when the boys asked the way to the nearest railroad, his answer was given in rather a relieved tone. It was as if he would be glad to have the silence to himself again.
