The greatest river in the world, then, begins in the vicinity of Key West, Florida. There is on the globe no such stupendous flow of waters. It defies the severest droughts; in the mightiest floods it never overflows. Its current sweeps onward more rapidly than the Mississippi or the Amazon and its volume is a thousand times greater. Let us rid our mind of the idea of land. The banks and the bottom of this stupendous river are of cold, whilst its current is of warm, water. The name of it is the Gulf Stream. It might properly be called the Atlantic River. Doubtless many hundreds, even thousands, of craft have made the voyage down this river from its source to its mouth, and the trip of the _Miosen_, of Christiania, Norway, is only remarkable in this: that she virtually drifted the whole distance, four thousand two hundred and twelve miles. The _Miosen_ is a Norwegian steamer of one thousand two hundred and eighty tons, and carried a cargo of molasses, rice, and tobacco from New Orleans to Christiania. After leaving New Orleans early in April, 1903, she encountered roughish weather in the Gulf of Mexico. But it was not until they had passed the Tortugas group that Captain Westrup suspected that there was anything radically wrong with the machinery. The _Miosen_ was fitted with old-fashioned Glasgow engines, and carried a sail in case of emergency. At Key West she put in for four days to see if the engineer could patch up the propeller sufficiently to enable the vessel to cross the Atlantic. "It was at Key West," said Captain Westrup, "I met an old fellow-mariner, a Swede. "'Going down the river?' he asked. "I laughed, not understanding the joke. "'No; I'm crossing the Atlantic,' I replied. "I then told him about the fractured propeller. "'Take my advice,' he said, 'and go by the river route. Like as not you'll drift the whole way, and if you're in no hurry you can give your engines a rest. A single sheet to the wind will do your job.' "It was the first time I had heard the expression 'river' as applied to the Gulf Stream. The idea entertained me. I already began to regard my forthcoming trip as a mere jaunt down a river, and with this in my head I took pains to note everything of interest connected with this stupendous stream. And here let me say that two leagues to the south-east of Key West the Gulf mariners point to a buoy labelled in prominent letters 'F. C.,' which stands for Florida Channel. It marks the end of the Gulf of Mexico and the beginning of the Atlantic River." [Illustration: THE BUOY IN FLORIDA CHANNEL.]
