Thus a rapid current passes from the gulf of Florida to the N.E. along the coast of North-America, known to seamen by the name of the GULF-STREAM. A chart of this was published by Dr. Francklin in 1768, from the information principally of Capt. Folger. This was confirmed by the ingenious experiments of Dr. Blagden, published in 1781, who found that the water of the Gulf-stream was from six to eleven degrees warmer than the water of the sea through which it ran; which must have been occasioned by its being brought from a hotter climate. He ascribes the origin of this current to the power of the trade-winds, which, blowing always in the same direction, carry the waters of the Atlantic ocean to the westward, till they are stopped by the opposing continent on the west of the Gulf of Mexico, and are thus accumulated there, and run down the Gulf of Florida. Philos. Trans. V. 71, p. 335. Governor Pownal has given an elegant map of this Gulf-stream, tracing it from the Gulf of Florida northward as far as Cape Sable in Nova Scotia, and then across the Atlantic ocean to the coast of Africa between the Canary-islands and Senegal, increasing in breadth, as it runs, till it occupies five or six degrees of latitude. The Governor likewise ascribes this current to the force of the trade-winds _protruding_ the waters westward, till they are opposed by the continent, and accumulated in the Gulf of Mexico. He very ingeniously observes, that a great eddy must be produced in the Atlantic ocean between this Gulf-stream and the westerly current protruded by the tropical winds, and in this eddy are found the immense fields of floating vegetables, called Saragosa weeds, and Gulf-weeds, and some light woods, which circulate in these vast eddies, or are occasionally driven out of them by the winds. Hydraulic and Nautical Observations by Governor Pownal, 1787. Other currents are mentioned by the Governor in this ingenious work, as those in the Indian Sea, northward of the line, which are ascribed to the influence of the Monsoons. It is probable, that in process of time the narrow tract of land on the west of the Gulf of Mexico may be worn away by this elevation of water dashing against it, by which this immense current would cease to exist, and a wonderful change take place in the Gulf of Mexico and West Indian islands, by the subsiding of the sea, which might probably lay all those islands int one, or join them to the continent.] 415 Cinctured with gold while _ten_ fond brothers stand, And guard the beauty on her native land,
