It is a curious fact worth recalling to memory that four hundred years ago, when Columbus first landed upon the island, he found that the aborigines kept turtle corrals near the beach, amply supplied with these animals. From them they procured eggs, and also furnished themselves with the only meat which it was possible to obtain, if we except that of the little "voiceless dog" which they hunted, and such birds as they could snare. Probably as many turtles were taken by those Carib Indians in 1492 as are caught by the fishermen this year of our Lord, in the same waters, showing how inexhaustible is the supply of Neptune's kingdom. Modern epicures may not therefore claim any distinction as to the priority of discovery touching turtle soup and turtle steaks, both of which were certainly indulged in by the Caribs in Columbus' time, and probably they were in vogue many centuries previous. One neither departs from nor approaches the Cuban shore without crossing that marvelous ocean river, the Gulf Stream, with banks and bottom of cold water, while its body and surface are warm. Its color, in the region of the gulf where it seems to have its rise, is indigo blue, so distinct that the eye can follow its line of demarkation where it joins the common waters of the sea in their prairie-green. Its surface temperature on the coast of the United States is from 75° to 80° Fahrenheit. Its current, of a uniform speed of four to five miles per hour, expends immense power in its course, and moves a body of water in the latitude of the Carolina coast fully two hundred miles wide. This aqueous body exceeds in quantity the rivers of the Mississippi and the Amazon multiplied one thousand times. Its temperature diminishes very gradually, while it moves thousands of leagues, until one branch loses itself in Arctic regions, and the other breaks on the coast of Europe. It is well known to navigators that one branch of the Gulf Stream finds its outlet northward from the Caribbean Sea through the Windward Passage, and that here the current extends to the depth of eight hundred fathoms; the width, however, in this section is not over ten miles. It will be nothing new to tell the reader that the sea, especially in its proximity to the continents, has a similar topographical conformation beneath its surface. The bottom consists of hills, mountains, and valleys, like the surface of the earth upon which we live. A practical illustration of the fact is afforded in the soundings taken by the officers of our Coast Survey in the Caribbean Sea, where a valley was found giving a water depth of three thousand fathoms, twenty-five miles south of Cuba. The Cayman islands, in that neighborhood, are the summit of mountains bordering this deep valley at the bottom of the sea. It is known to extend over seven hundred miles, from between Cuba and Jamaica nearly to the head of the bay of Honduras, with an average breadth of eighty miles. How
