Barnstable had been several hours on board his little vessel, which was every way prepared for their reception; and as soon as the heavy cutter of the frigate was hoisted on her deck, he announced that the schooner was ready to sail. It has been already intimated that the Ariel belonged to the smallest class of sea-vessels; and as the symmetry of her construction reduced even that size in appearance, she was peculiarly well adapted to the sort of service in which she was about to be employed. Notwithstanding her lightness rendered her nearly as buoyant as a cork, and at times she actually seemed to ride on the foam, her low decks were perpetually washed by the heavy seas that dashed against her frail sides, and she tossed and rolled in the hollows of the waves, In a manner that compelled even the practised seamen who trod her decks to move with guarded steps. Still she was trimmed and cleared with an air of nautical neatness and attention that afforded the utmost possible room for her dimensions; and, though in miniature, she wore the trappings of war as proudly as if the metal she bore was of a more fatal and dangerous character. The murderous gun, which, since the period of which we are writing, has been universally adopted in all vessels of inferior size, was then in the infancy of its invention, and was known to the American mariner only by reputation, under the appalling name of a “smasher.” Of a vast calibre, though short and easily managed, its advantages were even in that early day beginning to be appreciated, and the largest ships were thought to be unusually well provided with the means of offence, when they carried two or three cannon of this formidable invention among their armament. At a later day, this weapon has been improved and altered, until its use has become general in vessels of a certain size, taking its appellation from the Carron, on the banks of which river it was first moulded. In place of these carronades, six light brass cannon were firmly lashed to the bulwarks of the Ariel, their brazen throats blackened by the sea-water, which so often broke harmlessly over these engines of destruction. In the centre of the vessel, between her two masts, a gun of the same metal, but of nearly twice the length of the other, was mounted on a carriage of a new and singular construction, which admitted of its being turned in any direction, so as to be of service in most of the emergencies that occur in naval warfare. The eye of the pilot examined this armament closely and then turned to the well-ordered decks, the neat and compact rigging, and the hardy faces of the fine young crew, with manifest satisfaction. Contrary to what had been his practice during the short time he had been with them, he uttered his gratification freely and aloud. “You have a tight boat, Mr. Barnstable,” he said, “and a gallant-looking crew. You promise good service, sir, in time of need, and that hour may not be far distant.”
