 Apache. They had great fear of houses in which death

 Such customs prevented the building of permanent

 people lived scattered over considerable areas in large 

 family groups under a minor chief. Only at long 

 intervals and on special occasions did they all come 

 together for the celebration of tribal ceremonies. 



On the other hand the present day and prehistoric 

 sedentary peoples of the Southwest practised agri-

 be made to last from season to season. A provident 

 people makes provision against crop failure and feels 

 the need of at least a year's supply to ward off famine.
