In less than sixty hours they sailed, with a light but favorable wind. About 4 P. M. the second day, when they were nearly through the Mona passage, it fell calm. Within the passage, from shore to shore, there was not a ripple upon the water, and the light and buoyant little vessel, without advancing a foot, rose and fell with the mysterious undulation. A few miles ahead, without the passage, stretching from the east toward the west, the dark and ruffled surface was relieved by the white caps of the waves, whose tops were curling and breaking into sparkling foam. It was the trade wind sweeping, unobstructed by the land, toward the Great Bahama Bank. Several vessels were in sight, among them a large one, coming down before the wind, but which, less than any, excited their attention—for she seemed too burthensome for a Spanish trader to the colonies. “Captain,” said Talbot, half an hour after, “unless I am very much mistaken, that large stranger to windward is a man-of-war.” “Probably an Englishman.” replied the captain. “Scarcely, the canvas is not sufficiently dark, and the upper sails roach too much; it is evidently a frigate, and now I think of it, can hardly be a Frenchman, for they rarely cruise in this direction. Are you sure that there are no Spanish cruisers among the islands?” “None so large as this,” answered the captain, “for the Isabella went to leeward upward of a month ago.” “May it not have been a ruse?” asked Talbot. “Give me the glass,” said the captain, and he looked long and earnestly; “I cannot make her out,” he said at length, “but do not like her looks. Get out the sweeps, Mr. Long,” he added, addressing his lieutenant, “we must have the Humming-bird out of this mill-pond, or her wings will be useless.” The order was promptly obeyed, and the little vessel was soon moving at the rate of three or four knots through the water; but the larger vessel was in the mean time coming down at treble velocity. As soon as the schooner began to feel the influence of the wind, the sweeps were laid in, and all sail made to the northward, in the hope that the stranger would pass without observing them. In this, however, they were disappointed, for, as the latter was brought to bear abeam, they observed with anxiety, that she edged away toward them. “I fear that we have been deceived in our intelligence,” said the captain, in reply to a look from Talbot, as they noticed the suspicious movement of the stranger. “For Heaven’s sake, conceal your misgivings from Mr. Gillespie and his family while there is a hope,” asked Talbot; to which the captain nodded assent, and proceeded quietly to make his arrangements to elude, if possible, the grasp of his pursuer; for he now felt convinced that he saw the Isabella. The best sailing of the schooner was by the wind; instead, therefore, of keeping away before it, she was hauled close to it, and steered N. N. E. bringing the frigate to bear forward of the weather beam.
