Such a wealth of invention, such overpowering luxuriance, wore out the senses, wearied the soul. Both Jack and Dolores were glad when the sharp, salt smell of the sea struck knife-like through the enervating atmosphere. They had been travelling since dawn, and now, at noon, on the third day of their departure from Totatzine, they beheld the great waste of waters, flashing like a mirror in the sun. Jack should have greeted it as did the Hellens of Epaminondas, with a joyful cry of "Thalatta! Thalatta!" but he had forgotten his Greek, and was too weary to feel poetic. At this stage of their journey, they met with many Indians, who here landed in order to proceed to the shrine of the opal. Dolores was much afraid of their secret being discovered, and even Jack was somewhat doubtful of the efficacy of the vow of silence; but, in this case, as in others, fanaticism proved their safeguard, for they passed unharmed, even unspoken to, through the mass of savages. On arriving at the verge of the sea, Jack at once sought out the cave described by Cocom; and, leading Dolores thereto, for a short space of time, they were in safety. From this point, as Jack had learned in Totatzine, the city of Tlatonac was distant about twenty miles down the coast, and as there were plenty of canoes drawn up on the beach, it would have been easy for them to have proceeded at once on their journey. Gratitude to Cocom, however, prevented this, and they remained that night in the cave in order to await his arrival. The hiding-place was a natural cavern of wide extent, and, after making Dolores as comfortable as he could, Jack retired to the entrance, and kept guard, lest they should be surprised by some wandering savage. Throughout this perilous journey, nothing could exceed the tenderness and chivalry with which Duval behaved towards Dolores. He was tireless in his efforts to spare her all fatigues, in keeping up her spirits, in guarding her from all the annoyances consequent on travelling ill-provided through a dense forest. Dolores said nothing at the time, but took silent note of all this courtesy, and over and over again breathed a thankful prayer that the man whom she loved had proved himself so noble in the hour of danger. It was a disagreeable position to a girl brought up as she had been in strict observance of etiquette; but Jack came triumphantly through the ordeal, and gained rather than lost in her eyes by the nobility of his character, by the rare delicacy of his behaviour.
