Mem.—Each lipper of a wave works like tartar emetic on the lad in marine gear.” As no description of ours can give a more graphic account of the position of the two vessels in question, at the time named, than that which is contained in the foregoing extract, we shall take up the narrative at that moment, which the reader will see must, in the 43d degree of latitude, and in the month of June have been shortly after the close of the day. The young votary of Neptune, whose opinions have just been quoted, had indeed presumed on his knowledge of the localities, in affirming the distance and position of the cape, since the low sandy point was no longer visible from the deck. The sun had set, as seen from the vessel, precisely in the mouth of the Raritan; and the shadows from Navesink, or Neversink as the hills are vulgarly called, were thrown far upon the sea. In short, the night was gathering round the mariners, with every appearance of settled and mild weather, but of a darkness deeper than is common on the ocean. Under such circumstances, the great object was to keep on the track of the chase, during the time when she must necessarily be hid from their sight. Ludlow walked into the lee-gangway of his ship, and, leaning with his elbow on the empty hammock-cloths, he gazed long and in silence at the object of his pursuit. The Water-Witch was lying in the quarter of the horizon most favorable to being seen. The twilight, which still fell out of the heavens, was without glare in that direction; and for the first time that day, he saw her in her true proportions. The admiration of a seaman was blended with the other sensations of the young man. The brigantine lay in the position that exhibited her exquisitely-moulded hull and rakish rig to the most advantage. The head, having come to the wind, was turned towards her pursuer; and as the bows rose on some swell that was heavier than common, Ludlow saw, or fancied he saw, the mysterious image still perched on her cut-water, holding the book to the curious, and ever pointing with its finger across the waste of water. A movement of the hammock-cloths caused the young sailor to bend his head aside, and he then saw that the master had drawn as near to his person as discipline would warrant. Ludlow had a great respect for the professional attainments that his inferior unquestionably possessed; and he was not without some consideration for the chances of a fortune, which had not done much to reward the privations and the services of a seaman old enough to be his father. The recollection of these facts always disposed him to be indulgent to a man who had little, beyond his seaman-like character and long experience, to recommend him. “We are likely to have a thick night, Master Trysail,” said the young captain, without deeming it necessary to change his look, “and we may yet be brought on a bowline, before yonder insolent is overhauled.”
