"Francois," said the latter, impressively, "you know the terms on which I have consented to spare your life. Swear, then, by this cross; that you will be faithful to your trust; that neither treachery nor evasion shall be practised; and that you will, to the utmost of your power, aid in conveying these gentlemen to their destination. Kneel and swear it." "I do swear it!" fervently repeated the aubergiste, kneeling and imprinting his lips with becoming reverence on the symbol of martyrdom. "I swear to do dat I shall engage, and may de bon Dieu have mercy to my soul as I shall fulfil my oat." "Amen," pronounced the governor, "and may Heaven deal by you even as you deal by us. Bear in mind, moreover, that as your treachery will be punished, so also shall your fidelity be rewarded. But the night wears apace, and ye have much to do." Then turning to the young officers who were to be his companions,--"God bless you both; may your enterprise be successful! I fear," offering his hand to the younger, "I have spoken harshly to you, but at a moment like the present you will no longer cherish a recollection of the unpleasant past." The only answer was a cordial return of his own pressure. The Canadian in his turn now announced the necessity for instant departure, when the young men, following his example, threw their long guns carelessly over the left shoulder. Low, rapid, and fervent adieus were uttered on both sides; and although the hands of the separating parties met only in a short and hurried grasp, there was an expression in the touch of each that spoke to their several hearts long after the separation had actually taken place. "Stay one moment!" exclaimed a voice, as the little party now moved towards the gateway; "ye are both gallantly enough provided without, but have forgotten there is something quite as necessary to sustain the inward man. Duck shooting, you know, is wet work. The last lips that were moistened from this," he proceeded, as the younger of the disguised men threw the strap of the proffered canteen over his shoulder, "were those of poor Ellen Halloway." The mention of that name, so heedlessly pronounced by the brave but inconsiderate Erskine, produced a startling effect on the taller of the departing officers. He struck his brow violently with his hand, uttered a faint groan, and bending his head upon his chest, stood in an attitude expressive of the deep suffering of his mind. The governor, too, appeared agitated; and sounds like those of suppressed sobs came from one who lingered at the side of him who had accepted the offer of the canteen. The remainder of the officers preserved a deep and mournful silence. "It is times dat we should start," again observed the Canadian, "or we shall be taken by de daylight before we can clear de river."
