Messenger - Vol. 1, No. 3, Page 5 Spring 1992 Pieces of the past Barbara Hsiao Silber, Delaware '89, examines a stone point that was hand-hewn by Native Americans who migrated through Delaware some 4,000 years ago. Silber was crew chief at an archaeological site near St. Georges, Del., where the points, pieces of pottery and remains of several hearths were uncovered. The artifacts now are under analysis at the University's Center for Archaeological Research. Postholes from prehistoric pits at the site suggest that migratory households built doughnut-shaped subterranean houses, perhaps laying beams on the top and covering them with branches.
