She took his arm with a frank confidence that went to his heart; and once more laying by all serious thoughts, she entertained him, as they crossed the park, with her agreeable gaiety of mind. Near the Marble Arch they found a hansom, which rapidly conveyed them to the terminus at Euston Square; and here, in the hotel, they sat down to an excellent breakfast. The young lady's first step was to call for writing materials, and write, upon one corner of the table, a hasty note; still, as she did so, glancing with smiles at her companion. "Here," said she, "here is the letter which will introduce you to my cousin." She began to fold the paper. "My cousin, although I have never seen her, has the character of a very charming woman and a recognised beauty; of that I know nothing, but at least she has been very kind to me; so has my lord her father; so have you--kinder than all--kinder than I can bear to think of." She said this with unusual emotion; and, at the same time, sealed the envelope. "Ah!" she cried, "I have shut my letter! It is not quite courteous; and yet, as between friends, it is perhaps better so. I introduce you, after all, into a family secret; and though you and I are already old comrades, you are still unknown to my uncle. You go, then, to this address, Richard Street, Glasgow; go, please, as soon as you arrive; and give this letter with your own hands into those of Miss Fonblanque, for that is the name by which she is to pass. When we next meet, you will tell me what you think of her," she added, with a touch of the provocative. "Ah," said Challoner, almost tenderly, "she can be nothing to me." "You do not know," replied the young lady, with a sigh. "By the by, I had forgotten--it is very childish, and I am almost ashamed to mention it--but when you see Miss Fonblanque, you will have to make yourself a little ridiculous; and I am sure the part in no way suits you. We had agreed upon a watchword. You will have to address an earl's daughter in these words: '_Nigger_, _nigger, never die_'; but reassure yourself," she added, laughing, "for the fair patrician will at once finish the quotation. Come now, say your lesson." "'Nigger, nigger, never die,'" repeated Challoner, with undisguised reluctance. Miss Fonblanque went into fits of laughter. "Excellent," said she, "it will be the most humorous scene!" And she laughed again. "And what will be the counterword?" asked Challoner stiffly. "I will not tell you till the last moment," said she; "for I perceive you are growing too imperious."
