The well-known Spiro Mound, clearly prehistoric, furnished some examples of basketry, matting, cord, and cloth. The samples were sent to the writer by Mr. H. M. Trowbridge, Bethel, Kansas.

A comparison of materials in prehistoric collections reveals an excess of animal materials in the artifacts from Spiro Mound. One gets the impression that in Spiro textiles strings of vegetable fiber are usually surfaced with hair or other animal materials to increase the softness of the product. This may account for the almost exclusive use of canebrake and pawpaw, both relatively coarse fibers used without preliminary treatment. A striking contrast is between the slipshod way of making string and the highly precise fine techniques of covering it with hair and feathers.
