Round this bleak point the sea is often very rough and stormy. Icebergs, or huge blocks of ice, sometimes drift past this .cape. The Andes highland extends northward from Cape Horn. How long is this highland ? The widest part of the Andes highland is near the great bend in the Pacific coast. Here the ranges inclose a lofty plateau. On this part of the highland lies the beauti- ful Lake Titicaca. It is about two miles and a half above the level of the sea. Steamers cross this lake, and connect the villages with a railroad that winds down to the coast. Rich grainfields spread round Lake Titicaca, and the mountains that inclose its basin have rich silver mines. What part of South America is crossed by the equator ?? Near the equator stands a group of noted volcanoes. Among them the high plains wind like long avenues. Where is the isthmus of Panama? The Andes highland covers about one sixth of this grand division. The long slope of South America is east of the Andes highland.
