Leon came up to Mercedes, and to her surprise took her by the hand.

"Little sister," he said, "I have a very serious duty to perform. I have had another request for your hand."

The girl turned pale. "You know," she said, "that I do not intend to marry, Leon; I have told you so over and over again."

"That may be so, sister; but I believe that ladies change their minds in these matters not infrequently. The gentleman who is your suitor is not unknown to you. He is of good blood and honourable position. You will, perhaps, anticipate his name. It is the Cavalero Captain Arthur Hallett, a Knight of Isabella of the first class, and a Companion of the order of Fernando the Catholic."

The girl's face, which had been set with a mutinous expression, changed suddenly, a deep wave of colour rushed over her face, and her head drooped.

"He has my willing consent to the alliance, Mercedes; indeed, I know of no one in the world to whom I could so willingly commit you and your happiness."

"I know, señora," Arthur said, "that I am very unworthy of so great a gift, but at least I can promise to do my best to make you happy."

The girl lifted her head suddenly. "Do not say that you are unworthy," she said. "It is I who should say that. Have you not saved me from death? Have you not saved Spain from being ruined? It is I who feel, above all things, honoured by your love."

Then Leon said, with a slight smile: "I don't think that there is any occasion for me to lay my orders upon you on the subject. Take her, Arthur. I can trust her happiness in your hands with a certainty that my confidence will not be abused;" and he gave her hand to Arthur, who bent down and kissed her.

The two younger girls clapped their hands loudly. "Oh, Arthur!" Inez exclaimed, "I shall never call you Don Arthur again. We are pleased! We always knew that Mercedes was fond of you--anyone could have seen that with half an eye, but we did not know what you felt towards her. We are pleased, I cannot tell you how much! I believe we are more pleased than she is."
