Beverly, anxious to avoid a collision with the wild spirits of the neighborhood, which would be disagreeable, if not dangerous, to his guests, frankly related to Harold and Arthur the tenor of the conversation that had passed. Oriana was on fire with indignation, but her concern for Harold's safety had its weight with her, and she wisely refrained from opposing their departure; and both the young men, aware that a prolongation of their visit would cause the family at Riverside manor much inconvenience and anxiety, straightway announced their intention of proceeding northward on the following morning.
But it was no part of Seth Rawbon's purpose to allow his rival, Hare, to depart in peace. The chastisement which he had received at Harold's hands added a most deadly hate to the jealousy which his knowledge of Oriana's preference had caused. He had considerable influence with several of the dissolute and lawless characters of the vicinity, and a liberal allowance of Monongahela, together with sundry pecuniary favors, enabled him to depend upon their assistance in any adventure that did not promise particularly serious results. Now the capture and mock trial of a couple of Yankee strangers did not seem much out of the way to these not over-scrupulous worthies; and Rawbon's cunning representations as to the extent of their abolition proclivities were scarcely necessary, in view of the liberality of his bribes, to secure their cooperation in his scheme.
Rawbon had been prowling about the manor house during the day, in the hope of obtaining some clue to the intentions of the inmates, and observing a mulatto boy engaged in arranging the boat for present use, he walked carelessly along the bank to the old boat-house, and, by a few adroit questions, ascertained that "Missis and the two gen'lmen gwine to take a sail this arternoon."
The evening was drawing on apace when Oriana, accompanied by Arthur and Harold, set forth on the last of the many excursions they had enjoyed on James River; but they had purposely selected a late hour, that on their return they might realize the tranquil pleasures of a sail by moonlight. Beverly was busy finishing some correspondence for the North, which he intended giving into the charge of his friend Arthur, and he therefore remained at home. Phil, a smart mulatto, about ten years of age, who was a general favorite in the family and an especial pet of Oriana, was allowed to accompany the party.
It was a lovely evening, only cool enough to be comfortable for Oriana to be wrapped in her woollen shawl. As the shadows of twilight darkened on the silent river, a spirit of sadness was with the party, that vague and painful melancholy that weighs upon the heart when happy ties are about to be sundered, and loved ones are about to part. Arthur had brought his flute, and with an effort to throw off the feeling of gloom, he essayed a lively air; but it seemed like discord by association with their thoughts. He ceased abruptly, and, at Oriana's request, chose a more mournful theme. When the last notes of the plaintive melody had been lost in the stillness of the night, there was an oppressive pause, only broken by the rustle of the little sail and the faint rippling of the wave.
"I seem to be sailing into the shadows of misfortune," said Oriana, in a low, sad tone. "I wish the moon would rise, for this darkness presses upon my heart like the fingers of a sorrowful destiny. What a coward I am to-night!"
"A most obedient satellite," replied Arthur. "Look where she heralds her approach by spreading a misty glow on the brow of yonder hill."
"We have left the shadows of misfortune behind us," said Harold, as a flood of moonlight flashed over the river, seeming to dash a million of diamonds in the path of the gliding boat.
"Alas! the fickle orb!" murmured Oriana; "it rises but to mock us, and hides itself already in the bosom of that sable cloud. Is there not a threat of rain there, Mr. Hare?"
"It looks unpromising, at the best," said Harold; "I think it would be prudent to return."
