In the United States, there were some well-constructed houses for native Indians, ranging from the simple
brush shelter to the five-storied pueblo.
In the eastern United States, one of the existing types was that commonly know under the Algonkian name
of wigwam in which the Iroquois Indians lived. The wigwams were of wagon-top shape with straight sides
and ends, made by bending young trees to form the round shape. Over this shape pieces of tree bark were laid
to protect the Indians from bad weather. Over the bark dried grass was added. A small hole allowed smoke to
escape from the top. Doorways at each end served also as windows, The Iroquois Indians built trunk walls all
around their villages. The wall had only one opening, They could quickly close this opening if their enemies
came near.
Interestingly, the Choctaw Indians in Mississippi also lived in a wigwam of a most primitive (原始的)
construction, but different from those of the Iroquois Indians. The Choctaw Indians' wigwams, made from
mud, cane and straw, were in the form of a bee-hive. The covering was made of a long, tough grass. A post
in the centre supported the roof. A hole in the top admitted the light, and allowed the smoke to pass out.
The tipi tent-housing of the upper lake and plains area was put up with poles set lightly in the ground, tied
together near the top, and covered with bark and grass in the lake country. It was easily portable, and two
women could set it up or take it down within an hour.
The Pawnee, Mandan and other Indian tribes (部落) along the Missouri built solid ring-shaped structures
of trunk, covered with earth and dried grass, housing a dozen families.
