126 NICHOLLS'S SEAMANSHIP AND NAUTICAL KNOWLEDGE Docking Telegraphs are fitted in big ships, usually one at the stem and sometimes another at the bow. They are geared to their corres- ponding telegraphs on the bridge in the same way as the engine-room telegraph. The dials are marked so as to distinguish clearly between the mooring ropes on the starboard side and those on the port side as indicated in the adjoining illustration which, in this case, admits of the following orders being transmitted from the bridge to the officer attending to the mooring of the ship.
