“What does it matter?” I asked, impatiently. “We can surely keep away from Abdul Hashim and his people until morning, and by that time we ought to have gained possession of the treasure.”

The Professor shook his head, doubtfully; but he gave the command to march and we hurried away from this dangerous vicinity and approached the group of palms. The feet of the camels made no noise on the desert sands and our people were all too anxious and intent upon the adventure to speak unnecessarily; so like shadows we passed through the shifting and ghostly light that reached us from the stars, and soon gained our destination.

I had often wondered, in thinking upon the subject, how the Professor would be again enabled to locate with any degree of accuracy the buried treasure, situated as it was in a barren spot where the sand drove over it with every breeze. So now I watched him curiously as he dismounted at the palms and, drawing a line from one of the trees to another, seemed to pick out a star straight ahead to guide him and began pacing his way regularly over the desert. He gained an absolute regularity of pace in an amusing and ingenious, yet simple manner, attaching a cord from one of his ankles to the other, after carefully measuring its length. Consequently all his paces were mathematically equal, or could vary but slightly.

The rest of us followed him silently. I tried at first to count the number of paces, but from my high seat presently lost track of the count. But I had no idea it would matter to us; we should never be likely to visit this weird spot a second time.

At last the Professor came to a sudden halt and held up his hand. We leaped from our camels without waiting for them to kneel and two of our sailors promptly produced shovels from their panniers and began to dig in the spot the Professor indicated. They worked with steady industry, you may be sure, and we took turns relieving them at the task, for shoveling sand is by no means an easy job.

After going a certain depth without finding the granite slab we began making our pit wider, and within an hour a shovel wielded by Bryonia bounded back with a metallic sound that told us the search had finally been successful.

While the men quickly cleared away the remaining sand, disclosing three bronze rings imbedded in an oblong slab of granite, I could not help marveling at the Professor’s cleverness in locating the spot so accurately after several weeks of absence.

“It is a matter of simple mathematics,” he explained, while he watched the sand fly with eager eyes. “The only thing that could interfere with my calculations would be the removal of the palm trees. But I did not fear that, as they are centuries old.”

The big stone was now cleared of sand. The three sailors and Ned Britton stooped and put their shoulders to the slab, raising the ponderous weight slowly but surely until it stood upright on its edge. Then the Professor knelt down and with nervous haste threw out the padding of dried rushes and the thick layers of rotted mummy cloth that covered the contents of the vault.

Now, more gently, he began removing a number of bandaged cylinders, something like eighteen inches long and six inches in diameter. These, I supposed, were the rolls of papyrus bark that told the history of that dark period of Egypt between the Sixth and Twelfth Dynasties. From the tenderness with which Van Dorn handled these rolls—which he rewrapped in new canvas, sealed securely and then handed to Ned to be placed in one of the panniers—I had no doubt he considered them the most valuable and important part of the treasure. There were sixteen rolls; all of them, according to our bargain, Van Dorn’s personal property. After these had been cared for the Professor threw aside another layer of bandages and then, at last, the more tangible wealth of the powerful priests of Karnak was revealed to our wondering eyes.
