The floor of the cave ascended from the very threshold. Stony ridges circled from wall to wall. We climbed till we were two hundred feet from the opening, yet we were not half-way to the dome.
Our horses, browsing in the sage far below, looked like ants. So steep did the ascent become that we desisted; for if one of us had slipped on the smooth incline, the result would have been terrible. Our voices rang clear and hollow from the walls. We were so high that the sky was blotted out by the overhanging square, cornice-like top of the door; and the light was weird, dim, shadowy, opaque. It was a gray tomb.
"Waa-hoo!" yelled Jones with all the power of his wide, leather lungs.
Thousands of devilish voices rushed at us, seemingly on puffs of wind. Mocking, deep echoes bellowed from the ebon shades at the back of the cave, and the walls, taking them up, hurled them on again in fiendish concatenation.
We did not again break the silence of that tomb, where the spirits of ages lay in dusty shrouds; and we crawled down as if we had invaded a sanctuary and invoked the wrath of the gods.
We all proposed names: Montezuma's Amphitheater being the only rival of Jones's selection, Echo cave, which we finally chose.
Mounting our horses again, we made twenty miles of Snake Gulch by noon, when we rested for lunch. All the way up we had played the boy's game of spying for sights, with the honors about even. It was a question if Snake Gulch ever before had such a raking over.
Despite its name, however, we discovered no snakes.
From the sandy niche of a cliff where we lunched Wallace espied a tomb, and heralded his discovery with a victorious whoop. Digging in old ruins roused in him much the same spirit that digging in old books roused in me. Before we reached him, he had a big bowie-knife buried deep in the red, sandy floor of the tomb.
This one-time sealed house of the dead had been constructed of small stones, held together by a cement, the nature of which, Wallace explained, had never become clear to civilization. It was red in color and hard as flint, harder than the rocks it glued together. The tomb was half-round in shape, and its floor was a projecting shelf of cliff rock. Wallace unearthed bits of pottery, bone and finely braided rope, all of which, to our great disappointment, crumbled to dust in our fingers. In the case of the rope, Wallace assured us, this was a sign of remarkable antiquity.
In the next mile we traversed, we found dozens of these old cells, all demolished except a few feet of the walls, all despoiled of their one-time possessions. Wallace thought these depredations were due to Indians of our own time. Suddenly we came upon Jones, standing under a cliff, with his neck craned to a desperate angle.
"Now, what's that?" demanded he, pointing upward.
High on the cliff wall appeared a small, round protuberance. It was of the unmistakably red color of the other tombs; and Wallace, more excited than he had been in the cougar chase, said it was a sepulcher, and he believed it had never been opened.
From an elevated point of rock, as high up as I could well climb, I decided both questions with my glass. The tomb resembled nothing so much as a mud-wasp's nest, high on a barn wall. The fact that it had never been broken open quite carried Wallace away with enthusiasm.
"This is no mean discovery, let me tell you that," he declared.
"I am familiar with the Aztec, Toltec and Pueblo ruins, and here I find no similarity. Besides, we are out of their latitude. An ancient race of people--very ancient indeed lived in this canyon.
How long ago, it is impossible to tell."
"They must have been birds," said the practical Jones. "Now, how'd that tomb ever get there? Look at it, will you?"As near as we could ascertain, it was three hundred feet from the ground below, five hundred from the rim wall above, and could not possibly have been approached from the top. Moreover, the cliff wall was as smooth as a wall of human make.
"There's another one," called out Jones.
"Yes, and I see another; no doubt there are many of them,"replied Wallace. "In my mind, only one thing possible accounts for their position. You observe they appear to be about level with each other. Well, once the Canyon floor ran along that line, and in the ages gone by it has lowered, washed away by the rains."This conception staggered us, but it was the only one conceivable. No doubt we all thought at the same time of the little rainfall in that arid section of Arizona.
"How many years?" queried Jones.
