For anyone that might be interested in such things and find themselves in the area, much of the water works and related infrastructure is now part of the Lowell National Historic Park. The canals are still largely intact. One of the old industrial buildings, Wannalancit Mill, has been restored an= d turned into a museum. A bunch of years back I heard of plans to run the turbine at Wannalancit Mill for real as a demonstration, but I don't know i= f that ever happened. There is also a museum in another area, with canal tours available. It's all rather well done, and worth a afternoon if you'r= e interested in such things. Dave may chime in with more accurate and complete information. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
