As a matter of fact Andrew's man in the toga was not in evidence, except as the occasional imprint of a sandal on the floor of the cave suggested him. But the explorers were too busy surmounting the obstacles with which the tunnel was strewn to heed details that otherwise might have arrested their attention. The sharp edges of the rocky wall played havoc with their clothing, drawing from Miranda, incensed at his own rotundity, a choice series of expletives--fortunately in Spanish--and arousing the wrath even of Mrs. Quayle. After the first five hundred yards, however, the passage widened sufficiently for them to look about and take account of the perils--if there were any--facing them. The endless vista of rock, hewn in every conceivable shape and lighted dimly by the rays from their lamps, was dispiriting, to say the least. With the passing of the tunnel, however, and its alarming sense of premature entombment, even Mrs. Quayle experienced a faint return of confidence, while the schoolmaster, her companion in misery, began to feel a mild curiosity in the outcome of an adventure for the undertaking of which he had been the unwilling cause. He wondered vaguely to what further depths of this hole in the mountain the more enterprising spirits of the party would lead them. "I am sure I never came as far as this," he protested. "Well, what of that?" demanded Leighton. "He say he never come here!" crowed Miranda. "Very well, my leetle fellow, you are here now." "Yes, but--how far will we go?" he persisted. "You remember nothing of this?" asked Raoul. "I--I rather think I stopped in the beginning of the tunnel." "But here are the footprints," said Una eagerly. "They are made by sandals. I never wear sandals," said Andrew sadly. "Of course. They make by the other fellow." "By that man who wears a toga?" asked Mrs. Quayle anxiously. "It would be awful to meet him in this place." "She is afraid, this old lady--she have nerves!" announced Miranda. "She better go back." There being sound sense in the observation, the others stopped to consider it. "I could never find my way alone through that tunnel," declared Mrs. Quayle. As this was quite obvious, something had to be done. No one wished to desert the unfortunate lady; at the same time all, with the exception of Andrew, were anxious to press on without delay. Miranda, in terse Spanish, explained the difficulty to General Herran, who shrugged his shoulders disgustedly, expressing emphatic disapproval of women as explorers. "We must do something before we go any further," said Raoul. "There may be a long journey ahead of us." "Do you expect it?" asked Leighton. "I have no idea where we are." "That means----" "We have passed the dead wall." "Merciful heavens!" exclaimed Mrs. Quayle, "we are lost!" "Hardly that," said Una reassuringly. "It will be easy to go back the way we came. But this cave is too delightful to leave. I never breathed such air."
