Then the native again inspected his restored prayer mill. He gazed at it fondly, with a great smile of joy. He pointed at the spear and shuddered and shrank away from it. Then he fairly beamed on the young airman. He dropped to the ground and placed Dave’s foot on his neck. He acted as if he wanted his new friend to know that he was his slave for life.

After the man had gone through all these manœuvers Dave held up the ring. The native made a motion to describe a long flowing beard. Adrianoffski wore such and doubtless his partner did also. Now our hero felt certain that not only was the ring familiar to the native, but likewise that he was telling that its duplicate belonged to Ben Mahanond Adasse, and that he knew the merchant.

“Where?” spoke Dave, and exhausted his pantomimic skill in trying to express the word in signs. He pointed first in one direction and then in the other. His companion followed every gesture he made intently, seeming anxious to understand what he meant.

The man pointed to the southwest, and moved his finger along the horizon. He tried to express distance. The young aviator by signs conveyed the idea that he wished to see the owner of the other ring, the man with long flowing beard.

The native nodded a dozen times with intelligence and satisfaction. He promptly took up his knapsack and spear and faced about, posed to assume the part of a guide.

The pilot of the Comet did not wish to leave his friends without apprising them of his intentions. He motioned to the native to remain where he was. He then went up the hillside about half way. He knew that his comrades could now hear him.

Dave in a sing-song voice, so as not to make the native suspect that he was speaking to anybody, managed to tell Hiram and Elmer as to his plans. When he came back to the valley the man started away and Dave followed him.

It was not more than three miles from the hill that they began to near a high enclosure. It was formed of high, thick stakes driven close together, and was a kind of palisade. The native halted at its rear. He selected one knotted stake and ran up it with the agility of a monkey. He disappeared on the other side. Then there was the sound of a metal latch moving, and a section of the palisade opened. Dave’s guide pulled him inside a yard. He led the way to a flat, broad building that filled all the front of the place. They entered a room dimly lighted, piled high with furs, pelts and wicker boxes of merchandise. It was a great warehouse, the young airman surmised, stored with rich silks from Persia, teas from China, ivory and oils from India, and miner’s supplies for the secret, guarded gold mines of Thibet.

When they came to a door with a sash in its upper part, Dave glanced curiously through this window. The front of the building was open. Upon platforms there were displayed in great confusion all kinds of goods. A noisy throng was bartering and bustling about, as if it was some street fair. Beyond them were rude wooden wheeled vehicles, and yaks, camels, and even bison, used as beasts of burden.

Rude and uncultured as the native was, his loyalty to Dave seemed to arouse some instinct of caution. He motioned his companion to remain where he was, and passed out into the emporium. In a very few minutes he returned with a long-bearded man. Dave noted his resemblance in feature and dress to Adrianoffski.
