"The other well is dry, of course," said Lolita. In the slaty, many-ledged formation a little lower down the canon, towards the peep of outlying open country which the cloven hills let in, was a second round hole, twin of the first. Except after storms, water was never in this place, and it lay dry as a kiln nine-tenths of the year. But in size and depth and color, and the circular fashion of its shaft, which seemed man's rather than nature's design, it might have been the real Tinaja's reflection, conjured in some evil mirror where everything was faithfully represented except the water. "It must have been a real well once," said Luis. "Once, yes." "And what made it go dry?" "Who knows?" "How strange it should be the lower well that failed, Lolita!" The boy and girl were climbing down slowly, drawing near each other as they reached the bottom of the hollow. The peep of open country was blocked, and the tall tops of the mountains were all of the outer world to be seen down here below the mesa's level. The silence was like something older than this world, like the silence of space before any worlds were made. "Do you believe it ever can go dry?" asked Luis. They were now on the edge of the Tinaja. "Father Rafael says that it is miraculous," said the girl, believingly. Opposite, and everywhere except where they were, the walls went sheer down, not slate-colored, but white, with a sudden up-cropping formation of brick-shaped stones. These also were many-layered and crumbling, cracking off into the pool if the hand hung or the foot weighed on them. No safe way went to the water but at this lower side, where the riven, tumbled white blocks shelved easily to the bottom; and Luis and Lolita looked down these natural stairs at the portent in the well. In that white formation shot up from the earth's bowels, arbitrary and irrelevant amid the surrounding alien layers of slate, four black stones were lodged as if built into the wall by some hand--four small stones shaping a cross, back against the white, symmetrical and plain. "It has come farther--more uncovered since yesterday," Lolita whispered. "Can the Tinaja sink altogether?" repeated Luis. The arms of the cross were a measurable space above the water-line, and he had always seen it entirely submerged. "How could it sink?" said Lolita, simply. "It will stop when the black stones are wholly dry." "You believe Father Rafael," Luis said, always in a low voice; "but it was only Indians, after all, who told the mission fathers at the first." "That was very long ago," said she, "and there has always been water in the Tinaja Bonita." Boy and girl had set the jar down, and forgotten it and why they had come. Luis looked uneasily at the circular pool, and up from this creviced middle of the canon to the small high tops of the mountains rising in the free sky. "This is an evil place," he said. "As for the water--no one, no three, can live long enough to be sure."
