A large, unsightly tree stump on upper Water Street is gone. DPW workers came out Thursday afternoon and pulled and grinded the old stump down to nothing, leaving just sawdust. Remember it? The stump was about three feet tall and was the only thing left of a large maple cut down by the town almost three years ago.  Last spring the ugly stump briefly became home to the Lorax, Dr. Suess's mythical animal that speaks for the trees. An unknown artist made the plywood Lorax and left it on the tree, though it only lasted a few days before someone stole it. The DPW's Judy Fardig said there was talk more recently of having a Warren chainsaw artist shape the stump into a sea captain, but the stump was too rotted out to carve.
