Note 157 — APPENDIX A.

Wampum is the current money among the Indians. It is of two sorts, white and purple: the white is worked out of the insides of the great Congues into the form of a bead, and perforated so as to be strung on leather; the purple is worked out of the inside of the muscle shell. They are wove as broad as one's hand, and about two feet long; these they call belts, and give and receive them at their treaties, as the seals of friendship. For lesser motives, a single string is given; every bead is of a known value; and a belt of a less number is made to equal one of a greater, by so many as is wanted being fastened to the belt by a string.—Buchanan's North American Indians.
