Some pre-circumcision candidates in the Western Desert culture area are tak
en on a journey to gather people for the final ceremony. Since Aboriginal p
eople started to own cars in the 1960s, these journeys have expanded to suc
h an extent that the outward journey discussed here covered 2250 km. The qu
estion of why it is the initiation ceremony, rather than some other ceremon
ial form, that is becoming the basis for the integration of this expanding
Aboriginal domain is addressed and the fragmentary evidence on the historic
al growth of the journeys presented. Three kinds of ceremonial integration
are distinguished and a suggestion made as to why it is the initiation form
that is the focus of this expansion.
