[Various (1967)] Thus the 4750 ± 160 (Y-1761), confirmed by a Geochron Laboratory date of 4725 ± 60 (Gx-0762) obtained by the author on a hearth at the Twombly Landing site, Palisades Park, New Jersey and establishing an order of age for the narrow-bladed, stemmed, small point there, is the oldest date so far obtained for this tradition or "specific theme" in the Northeast or elsewhere. The actual projectile point dated by the Twombly hearth charcoal, which Ritchie has judged to resemble the Wading River style, was found within two feet of the hearth horizontally, and in the same stratigraphic situation. But the association is not direct. The point was found beneath an intact dump or small heap of shell that had to have been in place when the fire was kindled. The point may be a season or two older than the hearth, or a matter of decades, even centuries; it is impassible to say. But the 4750 date of the hearth is at least a stop-date forward for the earliest Taconic tradition point we know of and it can be relied on for this purpose. Attention should be called here to a recent development in C14 dating. It has been discovered, through comparison with tree ring dates and C14 dates from about 2200 B. P. to 6000 B. P. (Stuiver and Suess, 1966). During this period of about 4000 years the rate of divergence shows annual age as greater than C14 age according to the formula: Annual age = C14 age X 1.4-1100. The divergence begins to decrease after 6000 B. P. and at 10,000 B. P.
