Arequipa on Lake Titicaca is one of the pleasantest places in the world: mountain air, bright sunshine, warm days, cool nights, and a sparkling atmosphere dear to the hearts of star-gazers. The city lies on a plateau, surrounded by mighty snow-capped volcanoes, Chachani (20,000 ft.), El Misti (19,000 ft.), and Pichu Pichu (18,000 ft.). Arequipa is located on Puno bay. 

The bay of Puno grows quantities of totoras, giant bulrushes sometimes twelve feet long. Ages ago the lake dwellers learned to dry the totoras, tie them securely in long bundles, fasten the bundles together, turn up the ends, fix smaller bundles along the sides as a free-board, and so construct a fishing-boat, or balsa. Of course the balsas eventually become water-logged and spend a large part of their existence on the shore, drying in the sun. Even so, they are not very buoyant.  

Tiahuanaco, at the southern end of Lake Titicaca, in Bolivia, is famous for the remains of a pre-Inca civilization. Unique among prehistoric remains in the highlands of Peru or Bolivia are its carved monolithic images. Although they have suffered from weathering and from vandalism, enough remains to show that they represent clothed human figures. The richly decorated girdles and long tunics are carved in low relief with an intricate pattern. While some of the designs are undoubtedly symbolic of the rank, achievements, or attributes of the divinities or chiefs here portrayed, there is nothing hieroglyphic. The images are stiff and show no appreciation of the beauty of the human form. Probably the ancient artists never had an opportunity to study the human body. In Andean villages, even little children do not go naked as they do among primitive peoples who live in warm climates. The Highlanders of Peru and Bolivia are always heavily clothed, day and night. Forced by their climate to seek comfort in the amount and thickness of their apparel, they have developed an excessive modesty in regard to bodily exposure.

 Among the thirty-six islands in Lake Titicaca, some belong to Peru, others to Bolivia. Two of the latter, Titicaca and Koati, were peculiarly venerated in Inca days. They are covered with artificial terraces, most of which are still used by the Indian farmers of today. On both islands there are ruins of important Inca structures.  

The present-day Indians, known as Aymaras, seem to be hard working and fairly cheerful. During several months of the year everything is dried up and parched. The brilliant sun of the tropics, burning mercilessly through the rarefied air, causes the scant vegetation to wither. Then come torrential rains. Needless to say, such downpours tend to wash away the soil, which the farmers have painfully gathered for field or garden. The sun in the daytime is extremely hot, yet the difference in temperature between sun and shade is excessive. Furthermore, the winds at night are very damp; the cold is intensely penetrating. Fuel is exceedingly scarce, there is barely enough for cooking purposes, and none for artificial heat. 

Food is hard to get. Few crops can be grown at 12,500 feet. Some barley is raised, but the soil is lacking in nitrogen. The principal crop is the bitter white potato, which, after being frozen and dried, becomes the insipid chuño, chief reliance of the poorer families. The Inca system of bringing guano from the islands of the Pacific coast has long since been abandoned.
