“ These houses are sometimes built of stone, but oftener of adobe, several storeys high, each storey receding from the one below. The common plan is a hollow square or curved figure, though in some cases the form of a pyramid is followed. A feature of each town is the underground chamber used for tribal ceremonies. Many of the towns are built on high table-lands inaccessible except by steep trails. The Pueblos are a short, sturdy type of American Indians, very active, but mild-mannered and much darker than those of the plains. ”
