The use of a combined program written by R.G. Matson,

Dept. of Anthropology and Sociology, the University of

British Columbia, (for the main program), J.J. Wood, Dept.

of Anthropology, Northern Arizona University, (for the sub-

routine of hierachical grouping), and R.J. Sampson, (for

the subroutine to print dendrogram), permits the quick and

accurate calculation of Jaccard's coefficient of distance

among each pair of sites and the efficient grouping of

similarity. The results of the cluster analysis (simple

1
average) appear i n the form of a dendrogram (Fig. 2 ) .
"There is no necessary implication of •genetic* relation-

ship i n the dendrogram; i t should be interpreted merely

as an indicator of taxonomic distance, not as a family

tree" (Matson & True 1 9 7 0 i 1 2 0 2 ) . The dendrogram exhibits

1
the following patterns* (cluster I) sites 14, 3; (cluster
1
II) sites 18, 2, 11, 10; (cluster III) site 16; (cluster
IV) sites 17, 15; (cluster V) sites 6, 5, 4; (cluster VI)

sites 19, 8, 9t 7, 2; and (cluster VII) sites 3 and 1.

Cluster I, II, III and IV show exactly the same results

as that of traditional classifications. In other words,
