In accordance with the decision of the Fifth Radio- carbon Dating Conference, Cammbridge, 1962, all dates published in this volume (as in previous volumes) are based on the Libby value, IF 5570 ± 30 yr, for the half life. This decision was reaffirmed at the 8th International Conference on Radiocarbon Dating, Wellington, New Zealand, 1972. Because of various tnicertainties, when 1'C measurements are expressed as dates in years B.P. the accuracy of the dates is limited, and refinements that take some but not all uncertainties into account may be misleading. The mean of three recent determinations of the half life, 5730 ± 40 yr, (Nature, v. 195, no. 1845, p. 984, 1962), is regarded as the best value presently available. Published dates in years B.P., can be converted to this basis by multiplying them by 1.03. A.D./B.C. dates. As agreed at the Cambridge Conference in 1962, A.D. 1950 is accepted as the standard year of reference for all dates, whether B.Y. or in the A.D./B.C. system. 7 Meaning of 6''C. In Volume 3, 1961, we iudorsed the notation v (La- '-'C ment VI11, 1961) for geocliemical nmcasureumeats of activity, corrected for isotopic fractionation in samples and ill the NBS oxalic-acid standard. The value of 81'C that entered the calculation of -' was defined by refer- ence to Lamont VI, 1959, and was corrected for age. This fact has been lost sight of, by the editors as well as by authors, and recent papers have used 8'''C as the observed deviation from the standard. At the New Zealand Radiocarbon Dating Conferee cc it was recommended to use only for age-corrected saniples. Because we have 110 complete transcript of time reconnmiendations made by the conference, we will comment in more detail in the next issue of Radiocarbon. Radiocarbon Measurements: Comprehensive Index, 1950-1965.

Except where otherwise stated in the text, all samples were collected in 1970 or 1971 during fieldwork by one of the authors (M.B.), and were pretreated with hot 2N HCl to remove any possible contamination by pedogenic carbonate.
