One morning, when we were about in the latitude of the islands of Martin Vaz and Trinidad, we discovered, at daybreak, a large ship broad on our weather-bow, the topsails of which were just clear of the horizon. The trades were at this time blowing fresh, and the barque was thrashing along under her main-topgallantsail, with the flying-jib stowed. No sooner, however, did Roberts come on deck and espy the stranger--which was steering the same way as ourselves--than he must needs give orders to loose and set the fore-topgallantsail and flying-jib; and while I was in the saloon at breakfast, I heard him give orders to set the two royals. Under this additional canvas, which caused the little hooker to bury her lee side to her covering-boards, and to plunge to her hawse-pipes into the long ridges of swell that came rolling up from the southward and eastward, while she sent an acre of milk-white foam roaring and hissing away from under her lee bow, we rapidly overhauled the strange sail until we had brought her square abeam. Then, having allowed us to reach this position, her people gallantly responded to our obvious challenge, and made sail until they showed precisely the same canvas to the breeze that we did. The stranger, ship-rigged, was at this time about eight miles away from us, broad on our weather-beam, her hull just showing above the horizon when she rose upon the crest of a sea; and, after taking a good look at her through our glasses, we came to the conclusion that she must be a vessel of about twelve hundred tons. That she was a remarkably smart craft under her canvas soon became evident, for though we were going eleven and a half knots by the log, we found it impossible to gain an inch upon her after she had got her additional canvas fairly set and trimmed; indeed, there were times when it seemed impossible to resist the conviction that she was, if anything, gaining the merest trifle upon us. If so, however, it was only when the breeze came down with a little extra strength; for so surely as it softened at all we immediately appeared to recover the trifle that we seemed to have previously lost.
