“But, my beloved child,” said the mother soothingly, “even Jean Plessis himself says he would not be able to take us both to-night to the beach. You could not surmount the difficulties of the way. Besides, your presence would render us remarkable going through the gates; he has only a pass for two.”

Thus the mother soothed her little girl, showing her how necessary it was for the salvation of both that she should put herself under the care of the young midshipman. After a time Mabel Arden allowed herself to be persuaded.

William Thornton also talked to and soothed the child; and she looked so confidingly on him, and appeared to feel his kindness to her so much, that he vowed in his heart to suffer death sooner than Mabel should be injured whilst under his care.

“I was saying,” said the Duchess, rewarding our hero with a sweet affectionate smile, “that I wish to confide this casket to your charge till we meet again. In it there are important letters and papers respecting my daughter and her relatives in England, who will at once acknowledge and receive her. There are also a few jewels of value, and money; but I trust in God we shall be able to join you to-night in the boats. At what hour do you suppose you will leave the dock basin?”

“Perhaps, after ten o’clock, madame. It was very dark last night, when we passed through the shipping; and, as there is no moon, it will be nearly as dark to-night; or at all events, it will be only star-light. You ought, madame, to be provided with a dark lantern to show a light when your hear the noise of our oars, as we row along shore.”

“No doubt Jean Plessis will provide one,” said Madame de Coulancourt; “but you will remember the ruined quay; he says you cannot mistake the spot, as it is the only erection of the kind on that line of beach. I trust I am not detaining you too long,” said the Duchess; “I have now said all I have to say; so come, my beloved child, embrace me once more, and then I will confide you to the care of your young protector, whom may God prosper and preserve!”

Mabel threw herself into her mother’s arms; again and again she kissed her passionately, whilst the tears streamed down both mother’s and daughter’s cheeks.

William Thornton was considerably affected at witnessing the suffering the separation caused Mabel and the Duchess. He spoke some kind and assuring words to the little girl, and what he said appeared to abate her grief. Madame de Coulancourt then put a boy’s cloak over her shoulders, and a cap on her head, and then summoned Jean Plessis, who kept watch without. This faithful friend of the Duchess de Coulancourt was a tall and highly respectable-looking man, in years, scarcely forty, with a fine and expressive countenance. For several moments he conversed with our hero, respecting the place at which they were to meet that night; he described the inner and outward harbour accurately, and the best way for Lieutenant Cooke to steer on leaving the basin that night, and then covering the casket with a cloth cover, William Thornton took it under his care, remarking to himself that it was, for its size, uncommonly heavy.

“I shall go on before you, monsieur,” said Jean Plessis, “till I bring you in sight of the dock gates. Should you by chance be questioned as to who the boy is with you, say your superior officer ordered you to take him with you, and that he is an English lad; they will not attempt to stop you.”

Madame de Coulancourt was greatly agitated on parting. She embraced William Thornton as she would had he been her son, and, drawing a ring from her finger, begged him to keep it in remembrance of her. Our hero was greatly impressed; he was beginning very early, indeed, to be a protector to a young girl, scarcely three years his junior; but he felt proud of the confidence placed in him, and interested beyond measure. Taking the weeping and trembling Mabel by the hand, they passed out from the house, Jean Plessis going first to see that all was clear; then making a sign to William Thornton, they all three proceeded down the street.
