digs," Dr. Emerson told me. "Only a floating buoy marks the site." One day Edward Place of the Saint Law rence Seaway Development Corporation took me to a lonely spot on the New York shore north of Massena. "Under that bay lies the Tracy farm that gave its name to Tracy Landing," Ed said, "and over there is what's left of Long Sault Island. Swinging a Bridge of Ice "The river was so swift here it didn't freeze over in mild winters, but heavy ice formed alongshore. On a real bone-chilling day, a gang of men would cut loose a strip of shore-fast ice, a piece just long enough and a bit more to span the channel to Long Sault Island. They'd moor the lower end by posts and ropes to the mainland, and then let the current swing out the upstream end. "When the far end of the frozen raft struck 330 the opposite bank, it would freeze solid to the shore ice," Ed told me. "Then, as long as thick ice stayed, horses and sleds could go back and forth between the island farms and the mainland. They called it 'swinging the bridge.' " Towns and factories on both sides of the border already have put to work the kilowatts pouring from Moses-Saunders Powerdam. Some of the U. S. power will go as far as the Mohawk Valley and Vermont. Industries in Massena and its vicinity will use half the U. S. share of Moses-Saunders power, mostly to make aluminum. The people of Massena, incidentally, have a particular interest in the dikes along the edge of Lake St. Lawrence. Their business section is as much as 33 feet below the surface of the newly created lake. Aluminum making seeks out sources of abundant, inexpensive electricity. It takes 10,000 watts to smelt a pound of the metal.
