The Niagara Mail says, " two British ships, the Crysolite and Stornaway, have sailed a race from Canton with three American vessels, the Racehorse, Surprise, and 1 Challenge and the result is that both British ships have got homejirst, the American not having yet arrived," and adds, "and perhaps the Scientific American, who is an amateur in this sort of thing, will tell us the difference here between losing a race and being beat." We can, for we know all about it ; the Chrysolite and Stornaway, (both Aberdeen built clippers,) left Canton 11 days before the American ships. We never like tit make reckless statements; with an intention to mislead. Whenever it is shown that a British clipper ship has beat an American one in a fair race day for daywe will give the winning ship full credit for the same, and not feel the least chap-fallen. The Mail will now no doubt perhaps be kind enough to tell us since we have answered its question, why is it that none of the British skippers or ship builders have yet taken up the Boston challenge of 10,000 for a race from London to Canton and back between two ships, American and British of 1,200 tons burden each. If the British ships are swifter sailers, why do they fear to take up the challenge. There is more money in London than Boston, yet there the Boston challenge still stands unaccepted. Jonathan has thrown down his mailed glove to John, and he has not yet dared to lift it. If the people in Canada have such confidence in the Bitish ships, why do they not take up the challenge?
