It may be all very well to assert, that 'Britannia rules the waves,' and that 'Britons never will be slaves,' and so forth; only let us prove the assertions to be _true_, or not assert at all. We must appeal to the 'Shipping Intelligence' which comes to hand from every side, and determine, from actual facts, whether any one country really outsails another. Among the facts which thus present themselves to notice, is one relating to _clippers_. Who first gave the name of clipper to a ship, or what the name means, we do not know; but a clipper is understood to be a vessel so shaped as to sail faster than other vessels of equal tonnage. It is said that these swift sailers originated in the wants of the salmon shippers, and others at our eastern ports. A bulky, slow-moving ship may suffice for the conveyance to London of the minerals and manufactures of Northumberland and Durham; but salmon and other perishable articles become seriously deteriorated by a long voyage; and hence it is profitable in such case to sacrifice bulk to speed. Leith, Dundee, and especially Aberdeen, are distinguished for the speed of their vessels above those of the Tyne and the Wear; and the above facts probably explain the cause of the difference. The Aberdeen clipper is narrow, very keen and penetrating in front, gracefully tapering at the stern, and altogether calculated to 'go ahead' through the water in rapid style. As compared with one of the ordinary old-fashioned English coasting brigs of equal tonnage, an Aberdeen clipper will attain nearly double the speed. One of these fine vessels, the _Chrysolite_, in a recent voyage from China, traversed 320 nautical miles (nearly 370 English statute miles) in twenty-four hours: this was a great performance. But it must not be forgotten, that the United States claim to have attained a high ship-speed before England had thought much on the matter; the Baltimore clippers have long been known on the other side of the Atlantic as dashing, rapid, little vessels, mostly either single or double-masted.
