Paradoxically, in presenting fluted point measurements and proportions the percentage or ratio relationship of maximum (or minimum or average) fluting to total blade length is not completely a matter of mathematics. This seems to have escaped the notice of many students of the paleo-Indian flint industries. The problem involved has come to the attention of the writer in the course of studying several series of northeastern and Great Lakes area fluted points, with the result that he has been as frequently bewildered as enlightened in attempting to compare his data with those obtained by other archaeologists.
