The instant that they were seen there was a general rush for telescopes on the part of all the officers on deck; and after a protracted scrutiny of them the general consensus of opinion was that they were a French privateer and a British merchantman which she had captured.  Coming down toward us, end-on as they were, it was not easy at first to determine their rig, but both were large ships, one of them being of about six hundred tons, while the other appeared to be fully as big as ourselves. That their eyes were as sharp as our own very soon became evident; for while we were still peering at them through our glasses, we saw a string of flags go soaring aloft on board the smaller craft of the two, and immediately afterward both vessels slightly altered their course, the bigger of the two hauling up a couple of points to the southward and shaping a course that would carry her across our stern at a distance of about two miles, while the other very smartly clewed up her topgallantsails, took a single-reef in her topsails, and slightly hauled her wind, as though with the purpose of intercepting us.  This action on their part at once confirmed our suspicions as to their respective characters, and at the same time enabled us to determine that they were both full-rigged ships.
