"Well, as the Spaniards tried to get hold of it, the Indians took it inland to one of their forest retreats. The descendants of Montezuma, however, are still supposed to be its guardians, and, when one owner dies, the opal is brought secretly to Tlatonac, and shown to the new possessor; then it is taken back to its forest sanctuary." "Where did you see it?" asked Philip, curiously. "That's the whole point of the story," answered Jack, thoughtfully. "The son of Montezuma's daughter married a native woman, as I told you; their son, however, married a Spanish lady, and so the race was continued. Off and on, they married Indian and Spaniard. This mixing of race isn't good, from a philoprogenitive point of view, and Dolores is the last descendant of the original owner of the opal. Therefore, she is its guardian, and that is the reason Don Hypolito wants to marry her." "He wishes to obtain the stone as a wedding dowry?" "Yes. This Chalchuih Tlatonac is an object of superstitious veneration to the Indians. They are supposed to be converted; but they all more or less cling to their old beliefs. In one of these mysterious forests stands a temple to Huitzilopochtli, and there a good many of them go in secret to consult the opal. How they consult it I don't know, unless by its changing colours. Now, if Hypolito marries Dolores, through her he might seize the stone. If he becomes its possessor, he could do what he pleased with the Indian population. As they greatly outnumber the Spanish element, he would use them to raise himself to the Dictatorship of Cholacaca." "Then he doesn't love the girl?" "Not a bit," replied Jack, viciously; "all he wants is to marry her, and thus gain possession of the devil stone. Besides, apart from the use it would be to him, from a superstitious point of view, he would like to obtain the stone for its own sake. It is a magnificent gem." "Has he seen it also?" "Yes; at the same time as I did. Dolores' father died, and she became the ward of her uncle Don Miguel. I was a good deal about the house, and naturally enough fell in love with her." "Jack! Jack!" "You'll fall in love with her, yourself, Philip, when you see her; she's an angel." "Of course. You say that because you are in love with her. Does she return your love?" "Yes; she is as fond of me as I am of her." "And what does Don Miguel, the proud hidalgo, say?"
