In making up his mind as to the mode of proceeding on the present occasion, therefore, Captain Mull, while he had heard all that Mulford had to tell him, and had even encouraged Wallace to give his opinions, made up his decision for himself. After learning all that Harry had to communicate, he made his own calculations as to time and distance, and quietly determined to carry whole sail on the ship for the next four hours. This he did as the wisest course of making sure of getting to windward while he could, and knowing that the vessel could be brought under short canvas at any moment when it might be deemed necessary. The light was a beacon to let him know his distance with almost mathematical precision. It could be seen so many miles at sea, each mile being estimated by so many feet of elevation, and having taken that elevation, he was sure of his distance from the glittering object, so long as it could be seen from his own poop. It was also of use by letting him know the range of the reef, though Captain Mull, unlike Spike, had determined to make one leg off to the northward and eastward until he had brought the light nearly to the horizon, and then to make another to the southward and eastward, believing that the last stretch would bring him to the reef, almost as far to windward as he desired to be. In furtherance of this plan, the sheets of the different sails were drawn home, as soon as the boats were in, and the Poughkeepsie, bending a little to the breeze, gallantly dashed the waves aside, as she went through and over them, at a rate of not less than ten good knots in the hour. As soon as all these arrangements were made, the watch went below, and from that time throughout the night, the ship offered nothing but the quiet manner in which ordinary duty is carried on in a well-regulated vessel of war at sea, between the hours of sun and sun. Leaving the good craft to pursue her way with speed and certainty, we must now return to the Swash. Captain Spike had found the mooring of his brig a much more difficult task, on this occasion, than on that of his former attempt to raise the schooner. Then he had to lift the wreck bodily, and he knew that laying the Swash a few feet further ahead or astern, could be of no great moment, inasmuch as the moment the schooner was off the bottom, she would swing in perpendicularly to the purchases. But now one end of the schooner, her bows, was to remain fast, and it became of importance to be certain that the purchases were so placed as to bring the least strain on the masts while they acted most directly on the after body of the vessel to be lifted. This point gave Spike more trouble than he had anticipated. Fully one half of the remainder of the day, even after he had begun to heave upon his purchases, was spent in rectifying mistakes in connection with this matter, and in getting up additional securities to his masts.
