Anonymous, History of Steam on the Erie Canal
“ Hence, when fastened to a pier, it is all developed in its receding currents, and per contra when moving; if its machinery had a perfect fulcrum, it would all be developed in the run of the boat; consequently, on rivers and lakes, with fine-lined steamers, that cut the water like a knife, it is like standing in a small boat and pushing from a large one, but on canals, with their full bows, it is like standing in a large boat and pushing from a small one; the little one runs away with the power. ”
