When all was ready the fore weather-sheet was let go, and the lee-sheet hauled taut. The main-sheet was slacked off a little and the _Bessy_ proceeded on her way. It was a terrible half-hour; fortunately the dense heavy clouds had broken a little, and it was lighter than it had been, but this only rendered the danger more distinct. Once in the swashway, which is the name given to a narrow channel between the sands, the waves were less high. But on either hand they were breaking wildly, for there were still but four or five feet of water over the sands. The sea was nearly abeam now, and several times Jack almost held his breath as the waves lifted the _Bessy_ bodily to leeward and threatened to cast her into the breaking waters but a few fathoms away. But the skipper knew his boat well and humoured her through the waves, taking advantage of every squall to eat up a little to windward, but always keeping her sails full and plenty of way on her. At last they were through the swashway; and though the sea was again heavier, and the waves frequently swept over the decks, Jack gave a sigh of relief. They could make out the hull of the vessel now looming up black over the white surf that surrounded it. She had ceased firing, either from the powder being wetted or her guns disabled.
