SIX GREAT GATES.
HOW TIDES LIFTED THEM. The task of removing and repairing six giant lock weighing ICO tons each, has just been successfully completed by the L.M.S. Railway Company at Grangemouth Docks. These great gates, which control the entrance to the docks from the sea, measure 47ft by 35ft and in thickness vary from 2ft to over 6ft. They wore removed, rep a i red and replaced without interfering with tne working of the docks. , .. ~ For the removal the power or the sea itself was used by tli e engineers. The gates, which are hollow, and filled with water to give weight to them, were emptied and mad© water-tight, and the rising tide then floated them off their bearings. After being repaired they were towed back to the locks and placed over the hearings at high tide,; and with the ebb they sank slowly to rest.
