Boston—At a meeting of the Materials Research Society here earlier this month, a Malaysian and an American researcher presented a chemical analysis that links volcanic glass at a 6000-year-old archaeological site on Borneo to sources on islands 3500 kilometers to the east. The finding pushes back the earliest dates for long-distance sea trading on the Pacific by 2500 years, to 4000 B.C.
