Kāra stepped back a pace, and a part of the rock, circular in shape, swung slowly out into the passage, revealing another tunnel running at right angles with the first. Unlike the other, this was no natural fissure of the rock, but an excavation cleverly made by the hands of man. The roof was arched and the floor level and smooth.
The man slipped through the opening and proceeded along the arched passage. He did not close this door behind him, for Hatatcha had warned him not to do so. The floor had a gradual slope and he knew that he was going still farther beneath the mountain at every step. The atmosphere now became hot and stifling and he found it difficult to breathe; but he continued steadily walking for a matter of five minutes—which seemed an hour—holding the lamp before him, until finally he noticed the blaze of the wick flicker, as if a breath of fresher air had reached it.
By this time his breast had seemed ready to burst, and his breathing was fitful and gasping; but he hurried forward and now found the air cooler and fresher and drew it into his lungs gratefully.
The path was no longer downward, and before him he presently discovered a huge pillar of rock, which at first sight seemed to block the tunnel. Rude hieroglyphics were graven upon it. Passing around this at the left, he found himself in a high, vaulted chamber, and stopped with a sigh of satisfaction.
The chamber was circular in shape, and not more than sixteen feet in diameter. An air-shaft in the dome evidently led to some part of the summit of the mountain, for Kāra found himself breathing naturally again.
“This,” said he, “must be the library that Hatatcha mentioned.”
All around the walls of the vault were niches, cut in regular rows and containing box-like receptacles covered with inscriptions and pictures in gaudy colors. In the center of the room stood a large round slab of granite, finely polished upon its upper surface.
Kāra drew a box from its niche and set it upon the granite slab beside his lamp. Then he took from it a roll of papyrus, which he examined with interest.
Yes; he had read it before. It was one of those so often mysteriously produced by his grandmother to assist in his education. He examined another roll, and a third, leisurely and with care. These also he knew well. There were two hundred and eighteen rolls of papyrus in this ancient library, and the knowledge they contained had all been absorbed by the young Egyptian years before. He read them easily, and knew at once from their context the different meanings of many signs that are yet puzzling less-favored students of the hieroglyphics.
The manuscripts dated from the fourth dynasty down to the days of the Ptolemies, and, in a large cavity below the rolls of papyrus, were ranged the earlier works of Herodotus, Diodorus Siculus, Manetho, Horapello, Strabo and others, as well as the volumes on modern Egyptian and European history that old Hatatcha had purchased in Cairo within the last few years. Several historical stelæ of the earlier kings of Egypt also leaned against the walls, arranged in chronological order, and this library, founded by Ahtka-Rā, which had been preserved and added to for so many centuries, was a veritable storehouse of the records of his remarkable country.
