You can learn alot about a tree by slicing through it and looking at its cross section. Unfortunately it kills the tree too, so we don't recommend this. But Dr. Neil Pedersen is Research Assistant Professor in the Tree Ring Laboratory at Lamont-Doherty Easth Observatory at Columbia University and he's an expert at figuring out what ancient trees were used to construct historic buildings and boats, including the Bush-Holley House in Greenwich, by inspecting the tree rings that remain. Hear him speak Thursday at the Greenwich Historical Society. Go science!
Greenwich Historical Society, 39 Strickland Road, Greenwich. Thu., Jan. 24, 7 p.m. Free, reservations suggested. (203) 869-6899, ext. 10. greenwichhistory.org.
