 Great hauling power being necessary, and, as it was not possible to execute a powerful pull directly from the tugs working in the shoal water, it was decided to do the work by means of heavy steam capstans on shore. Chain cables were passed through the bow hawse pipes of the wreck, and connected by 8in. wire ropes to the shackles on the shore station. These were passed through a ioo-ton leading block, to which in turn were shackled ioo-ton wire purchases, the falls being taken to the capstans. Pumping operations were then com- menced, but in consequence of the great damage amidships, it was considered impracticable to pump out the two damaged boiler rooms. This first pumping operation resulted in the vessel altering her angle of heel by io deg., and she was considerably eased up from the bed by the pontoons. The capstans were started, and the attendant tugs were utilised as far Copyright. Photo No. 60. One of the Steel Pontoons being placed in position. as possible. After the vessel had been moved about 6ft. shorewards, she was brought up owing to the forward bridge, which projected beyond the tumble-home of the hull, cutting into the sea-bed. The velocity of the tide being- so great, it was decided not to continue the oper- ation, but the vessel had already been swung parallel with the shore. The forward bridge was removed, the pumps were restarted, and the capstan^ and tugs succeeded in moving the ship a further 30ft. inshore. It was then decided to proceed with the work of uprighting the vessel. Five additional cylinders had in the meantime been constructed, each of these later ones being divided into three compartments. The sizes of the seven cylinders used were : one 75ft. by 12ft. dia. ; two 40ft. by 12ft. ; two 50ft. by 10ft. ; and two 50ft. by 12ft. The five first mentioned were arranged on the starboard side, the largest being placed alongside the l34
