The Navaho are an Athabascan tribe of nomadic or semi-nomadic habit
occupying a reservation in northeast Arizona, northwest New Mexico
and southeast Utah. In 1906 they were roughly estimated at 28,500.
Sheep raising and weaving are their main industries. In many ways
their ceremonial life appears like that of their neighbors, the Pueblo
Indians, but the relationship of the two peoples in ceremonialism, as
in other respects, has not been studied.
