Ali straightened unconsciously as he thought of the day Lieutenant Beale's expedition had left Fort Defiance and started west. His mind became a screen upon which appeared a complete review of every single day that had followed. Ali lived again, as he had before, the whole exciting caravan into unknown wilderness.

Then, skipping his two years in California, Ali rode Ben Akbar back to the Colorado and the massed wagons awaiting ferry transport. There followed, in complete detail, his return ride over the road. Again he saw the burgeoning civilization that had overrun a virgin wilderness. Finally, he knew the right answer, and knowing, must question no more.

The camels had not yielded to any petty thing, but had bowed to a force so powerful that nothing could stand against it. All the armies of all the world could bring human progress to no more than a temporary halt, and not even the swiftest dalul could hope to keep pace with the breathtaking march of civilization as America knew it. If the camels had been imported fifty years sooner, or if America had been satisfied to wait fifty years longer to develop her wilderness, then indeed would all Americans know the true worth of camels.

As the course was run, most Americans would know camels only as legendary ships of the desert or exotic imports whose proper abode was the circus or zoo. Those few who did learn about the Camel Corps, might hear of it as a glaring example of the hare-brained schemes that may be dreamed up by scatter-brained people. Nevertheless, Ali was suddenly happy and again knew a complete peace.

He and Ben Akbar were reunited never to be parted again, and he, at least, knew the true story of the Camel Corps. Nothing anyone might say or do could change in the smallest detail what had already been done. The people who spilled over Lieutenant Beale's wagon road might never know that the pillars of their churches, the foundations of their schools, their homes, their very way of life, were anchored on long-forgotten camel tracks. But they would not be there if camels had not led the way.

Given only one real opportunity, the camels had contributed more than their full share. Ali knew finally that, if he might return over the years and once more look at camels being taken aboard the Supply, and if he might also look ahead and see all the future, he would again do as he had done and come to America.

The journey had not been in vain. What had seemed to be heartbreaking failure showed its true colors under the correct light. Triumph was complete.

Ali stood up. "Rise," he said.

Slowly, Ben Akbar rose to his feet and the two started along the silvery path together.
