From the capstans, to stout chain cables passed through the hawse pipes at the bows of the cruiser, stretched very strong wire ropes, each able to stand a strain of about 400 tons. feet until she lay parallel to the shore. At this point her forward bridge fouled with the bottom, and operations came to a standstill while the obstruction was being removed with the aid of pneumatic tools. A second spell of hauling brought her 10 yards nearer shore, DIAGRAM TO SHOW PURPOSE OF “ CAMELS ” AND TRIPODS. A, “Camels ” fixed (c in its first position).

When all was ready the pumps began to draw water in cataracts from the interior of the vessel, while air-compressors forced the water out of the camels. Sim- ultaneously the capstans got to work, and sundry tugs lent their assistance. The com- bined effects of increased buoy- ancy and haulage were soon felt, and the Gladiator's bows swung slowly round for 6 and then the winding cable gave way ; so she was allowed to remain in this position while preparations were made for the more difficult process of bringing her on to an even keel. For this task the shore capstans were of no use, as the masts, which would give the necessary leverage, pointed land- wards. The Ranger and Enterprise were ac- cordingly brought up and moored by 7-ton anchors, in line with the two masts, and at THE MASTS ABOVE WATER—TUGS PULLING ON ROPES OVER TRIPODS. Photo, S.

Since a direct pull on the masts would have tended vessel into deeper water, two great tripods were erected on the port side, abreast of the masts. Over their tops passed the hauling ropes from the salvage steamers to the mast- heads, so that the pull on these last might be obliquely upwards.
