While Francis reassured her, the last seconds of the last minute for the peon were ticking off. And when, summoning all his courage, he thrust his hand into the mouth of the goddess, the last second ticked and the clock struck. With a scream of terror he pulled back his hand and gazed at the wrist where a tiny drop of blood exuded directly above an artery. The mottled head of a snake thrust forth like a mocking, derisive tongue and drew back and disappeared in the darkness of the mouth of the goddess.

“A viperine!” screamed Leoncia, recognising the reptile.

And the peon, likewise recognising the viperine and knowing his certain death by it, recoiled backward in horror, stepped into the hole, and vanished down the nothingness which Chia had guarded with her feet for so many centuries.

For a full minute nobody spoke, then the old priest said: “I have angered Chia, and she has slain my son.”

“Nonsense,” Francis was comforting Leoncia. “The whole thing is natural and explainable. What more natural than that a viperine should choose a hole in a rock for a lair? It is the way of snakes. What more natural than that a man, bitten by a viperine, should step backward? And what more natural, with a hole behind him, than that he should fall into it——”

“That is then just natural!” she cried, pointing to a stream of crystal water which boiled up over the lips of the hole and fountained up in the air like a geyser. “He is right. Through stone itself the gods work their everlasting will. He warned us. He knew from reading the knots of the sacred tassel.”

“Piffle!” Francis snorted. “Not the will of the gods, but of the ancient Maya priests who invented their gods as well as this particular device. Somewhere down that hole the peon’s body struck the lever that opened stone flood-gates. And thus was released some subterranean body of water in the mountain. This is that water. No goddess with a monstrous mouth like that could ever have existed save in the monstrous imaginations of men. Beauty and divinity are one. A real and true goddess is always beautiful. Only man creates devils in all their ugliness.”

So large was the stream that already the water was about their ankles.

“It’s all right,” Francis said. “I noticed, all the way from the entrance, the steady inclined plane of the floors of the rooms and passages. Those old Mayas were engineers, and they built with an eye on drainage. See how the water rushes away out through the passage.—Well, old man, read your knots, where is the treasure?”

“Where is my son?” the old man counter-demanded in dull and hopeless tones. “Chia has slain my only born. For his mother I broke the Maya law and stained the pure Maya blood with the mongrel blood of a woman of the tierra caliente. Because I sinned for him that he might be, is he thrice precious to me. What care I for treasure? My son is gone. The wrath of the Maya gods is upon me.”
