Camels could move faster than mules, over the bad footing. Gray would make his start four days—three if the Kirghiz arrived promptly—later than Sir Lionel. And he would fall behind steadily.

If it had been possible, he would have gone alone. But he could not carry the necessary food and water for ten days. For a moment he pondered the advisability of pushing on alone as soon as the mules could be bought.

This plan he dismissed as useless. Mirai Khan had assured him that it would take at least two days to get the animals and the needed supplies. Also, he would be without a guide—for Mirai Khan would not start until the tribesmen arrived.

It would be tempting providence for one man to venture with a string of mules into the Gobi. Even so, Gray might have attempted it if he had a guide.

There was nothing for it but to wait. And Gray passed the time as best he could, overhauling his rifle and small stock of ammunition, and packing with the help of Mirai Khan the food the latter bought for him.

Fate moves in strange ways. If Gray had started before the four days were up, the events that took place in the Gobi would have shaped themselves differently. For one thing, he would not have seen the tracks of the wild camel in the sand.

Nor would he have heard the story of the pale sickness.

As Mirai Khan had assured him, the Kirghiz tribe appeared at Ansichow the evening of the third day. The hunter took Gray to their aul near where Sir Lionel's encampment had been.

Acting as interpreter, he harangued the newcomers. Moreover, as he informed the American later, he did not translate what Gray said literally. If he had done so, he asserted, they would not have gone into the Gobi.

The reason that Mirai Khan set forth seemed sufficient, for after long debate, the elder of the tribe and two evil looking hunters consented to accompany Gray. They agreed to go on foot. Somewhat to the American's surprise nothing was said about turning back.
