[Various (1967)] Its theme is the stemmed point, and a stemmed point, according to those who have learned the art of flint knapping, is harder to shape than a notched-blade point. For the latter, once a satisfactorily thin ovoid or trianguloid blank has been roughed out, notches can be worked in at will anywhere, from any angle and to any depth with a punch-like flaking tool and a few twists of the wrist. The stemmed point requires that the stem be shaped in the blank. Many accomplished workers in notched blades will not even try to produce a stemmed point; they can produce much more exotic looking pieces by pressure flaking of blanks made out of flakes. The fact that the Taconic theme is a simple stemmed point makes it a fairly simple one to recognize. What can be said in summary, then, is that within a projectile point tradition of any time duration there will be phases, that is, groups of points of clearly similar style that may be called "vogues," or the fashion of particular moment, and there will be intermediates, hybrids, and erratics. All this is what we would expect of a line of individually handmade items, but it makes difficult the creation of a model of the tradition. The only possible model, as implied in the definition, is evolutionary, a model of change through time. This would long since been done pragmatically for the Taconic series of points had we the kind of stratified sites worked by Coe.
