"Chinese merchants, Excellency, or perhaps Turkestan traders from Kashgar."

Mirai Khan's respect for his companion had increased with the last few days. Gray's accurate shooting inspired his admiration, and the fortitude of the man surprised him.

On his part, Gray trusted the Kirghiz. If Mirai Khan had meant to rob him, he had enjoyed plenty of chances to do so. But the Kirghiz's code would not permit him to steal from one who was sharing his bread and salt.

"If they are Chinese," meditated the American, "it will not be wise to ride up to their camp. What say you, Mirai Khan?"

The Kirghiz puffed tranquilly at his noisome pipe.

"This. It is the hour of sunset prayer. When that is ended you and I will dismount, Excellency, and stalk the encampment. By the favor of God we will then learn if these people are Chinese or Turkomans. If the last, we shall sleep in a dry aul, which is well, for my bones like not the damp."

Whereupon Mirai Khan removed his pipe and kneeled in the sand, facing toward the west, where was the holy city of his faith. So poverty-stricken was he that he did not even own a prayer carpet. Gray watched, after tethering the three animals.

"Remember," he said sternly when Mirai Khan had finished the prayer, "there must be no stealing of beasts from the camp, whatever it may be."

The Kirghiz's weakness for horseflesh was well known to him. The hunter agreed readily and they set out under cover of the rain. By the time they were half way to the caravan the sudden twilight of the Gobi concealed them.

Guided by the occasional whinny of a horse, or the harsh bawl of a camel, Mirai Khan crept forward, sniffing the air like a dog. Several lights appeared out of the mist, and Gray took the lead.
