146 INDIANS OF THE SOUTHWEST. 
The Navajo live in winter in earth-covered lodges. 
The house has for its chief support three large logs with 
forked tops. These are locked together by placing 
the fork of one in the fork of a second, and thrusting 
the fork of the third between them. Other logs and 
small poles are laid on these until a conical house is 
enclosed. Brush is placed in the larger cracks and 
Navajo House. 
earth is piled on to a depth of several inches. Such 
a house only leaks after a long, hard rain. A doorway 
is made on the east side and between the doorway and 
the apex a large hole is left to admit light and air and 
through which the smoke may escape.  Six-sided 
houses are also built of logs placed horizontally. By 
drawing them in gradually after the walls have been 
carried to a proper height, the roof is formed. A 
smoke hole is left at the apex. During the summer the 
Navajo generally camp with only a shelter of brush or a 
stone wall to protect them from the prevailing winds.
