[Various (1971)] Farther east, in southern New England, we have a hearth charcoal radiocarbon date of 2270 B.C. ± 160 years (Y-1530) attributable to a weak Laurentian manifestation in Stratum 4 at the Hornblower II site on Martha's Vineyard (Ritchie 1969b: 52, 213, 220); another date of 2350 B.C. ± 250 years (M-696) on charcoal from a cremated burial with a ground stone ulo at the Wapanucket No. 6 site in Middleboro, Mass. (Robbins 1960: 32); and a very similar date of 2390 B.C. ± 120 years (Y-1664) for hearth charcoal from the Vosburg level of the Binette site in Naugatuck, Conn. (Thompson 1969). For the Brewerton phase of central New York (Ritchie 1965a: 87-103) there are only two dates, both from hearth charcoal in the Brewerton horizon at the base of the stratified O'Neil site in Cayuga County. These dates are 2050 B.C. ± 220 years (I-424) and 2010 B.C. ± 100 (Y-1273) (Ritchie 1965a: 91; Ritchie and Funk, n.d.a). A supporting figure of 1900 B.C. ± 95 years (I-5266) for these approximately 4000-yearold Brewerton features was recently obtained on a sample of human bone from our excavations on the Frontenac Island site, also in Cayuga County.
