The Atlantic Ocean is one of the oceans that separate the Old World from the New．For centuries it kept the America from being discovered by the people of Europe．

　　The Atlantic Ocean is only half as big as the pacific, but it is still very large．It is more than 4,000 miles （6,000 km） wide where Columbus crossed it．Even at its narrowest it is about 2,000 miles （3,200 km） wide．

　　There is so much water in the Atlantic that it is hard to imagine how much there is．But suppose no more rain fell into and no more water was brought to it by rivers．It would take the ocean about 4,000 years to dry up．On the average the water is a little more than 2 miles （3．2 km） deep, but in some places it is much deeper．The deepest spot is near Puerto Rico．This "deep" measures 30,246 feet --- almost six miles （9．6 km）．

　　Several hundred miles eastward from Florida there is a part of the ocean called the Sargasso Sea．Here the water is quiet, for there is little wind．Today the Atlantic is a great highway．It is not, however, always a smooth and safe one．Storms sweep across it and pile up great waves．Icebergs float down from the Far North across the paths of ships．We now have such fast ways of travelling that this big ocean seems to have grown smaller．Columbus sailed for more than two months to cross it．A fast modern steamship can make the trip in less than four days．Airplanes fly from New York to London in only eight hours and from South America to Africa in four!
