Barbara and Barry Zucker--- Pinchoff, both doctors from New York City, took their three
daughters on a walking safari(旅行)last year in Tanzania. Barbara told about their experience in
Kinbero, "It is the most remote(遥远的)place we have ever been to," camping with a few other
Americans, two Tanzanian guides, and several Hadza(哈扎人)who had time to sit and chat
because they had just killed a giraffe.
About 400 members of the Eastern Hadza tribe(部落)live in Tanzania today, the only
hunter-gatherers who remain in Africa. The Hadza hunt game, gather edible plants and honey,
and move from place to place whenever the weather changes. Every two weeks or so, they move
to a new campsite.
At the Pinchoffs' campsite, three Hadza men stopped by to visit and ended up staying three
days. One of the guides gave the men a cigarette. They took out the tobacco, put it in a pipe, and
lit the pipe with fire they started.
It takes less than two hours for Hadza women to build a new camp. They make huts(茅屋)by
bending branches into round structures about six feet high, and then covering them with long,
golden grass. If the weather is very wet, the women may choose a dry cave to set up a camp. Some
rock caves have been used over thousands of years and are decorated(装饰)with ancient rock
paintings. Whether they sleep in huts, caves or in the open, the Hadza cover themselves only with thin
cloths and depend on fire to keep them warm.
The Hadza refuse to be "settled" into villages or to have the life of farmers. By 1979, almost all of
them had returned to their old ways. They Hadza may be the only tribe in Africa that has never paid
taxes.
