"Joe is our friend—our only friend!"

"Eh?" exclaimed Miss Maclan, unable to believe she had heard aright, as she fastened a frightened look on the speaker; "The Lieutenant our friend—you are jesting!"

"I repeat that he is our most devoted friend; I more than know it—I hold the proof of it."

"Oh, dear me!" ejaculated Ulla, in almost comic surprise, it was so extreme.

"Yes," went on Rosario, "when I was left by myself, he came to me, profiting by Captain Kidd's absence. He made his true character known to me, and pledged entire devotion. He said that he was in the caravan to guard and save me. After recommending me to be as wise as possible, he left me the most undeniable proof of his good faith, proof that would turn terribly against him if he were to betray me instead of serving me. What do you think of that?"

"Oh, that explains your having been so strange and excited when I came back to you," cried Miss Maclan, clapping her hands incautiously. "I understand now. But why did you not let me know before? This was unkind, as I was so uneasy about you."

"Don't bear me any ill will, for I was distraught with sudden gladness."

"What an amazing thing. That Joe fellow is very ugly," said Miss Maclan, merrily; "but I shall try to love him now!"

"Now it is you who are excited, girl. Calm yourself, lest we be overheard."

"No, no, there is nothing to fear, at least, in the immediate present. Oh, dear Rosario, what a blessing this is for you, and perhaps for me, for I am to keep by you, am I not? What a mercy it will be to flit through the grip of that nasty Captain Kidd, a gallows bird, who never even blinks behind his spectacles."
