Dr. Cairn, taking advantage of the rugged walls, and of the blocks of stone amid which they stood, mounted upon Sime's shoulders.
"Could you carry your revolver in your teeth?" asked the latter. "I think you might hold it by the trigger-guard."
"I proposed to do so," replied Dr. Cairn grimly. "Stand fast!"
Gradually he rose upright upon the other's shoulders; then, placing his foot in a cranny of the rock, and with his left hand grasping a protruding fragment above, he mounted yet higher, all the time holding the lighted lamp in his right hand. Upward he extended his arms, and upward, until he could place the lamp upon the ledge above his head, where its white beam shone across the top of the shaft.
"Mind it does not fall!" panted Sime, craning his head upward to watch these operations.
Dr. Cairn, whose strength and agility were wonderful, twisted around sideways, and succeeded in placing his foot on a ledge of stone on the opposite side of the shaft. Resting his weight upon this, he extended his hand to the lip of the opening, and drew himself up to the top, where he crouched fully in the light of the lamp. Then, wedging his foot into a crevice a little below him, he reached out his hand to Sime. The latter, following much the same course as his companion, seized the extended hand, and soon found himself beside Dr. Cairn.
Impetuously he snatched out his own lamp and shone its beams about the weird apartment in which they found themselves—the so-called King's Chamber of the pyramid. Right and left leapt the searching rays, touching the ends of the wooden beams, which, practically fossilised by long contact with the rock, still survive in that sepulchral place. Above and below and all around he directed the light—upon the litter covering the rock floor, upon the blocks of the higher walls, upon the frowning roof.
They were alone in the King's Chamber!
