The majority then set forth that no canal with locks can fulfil these requirements and that the sea-level canal is the only type of canal that can give reasonable assurance of safe and uninterrupted navigation. They refer to three accidents in the preceding nine years arising from collisions between steamers and lock gates on the "Soo," and to three accidents of a like nature on the Manchester Canal, and to the disastrous results that would have followed such accidents at the locks
