Faster and faster it went and yet it seemed a long time before they plunged into the water, which was nigh a hundred feet below the surface.

Fortunately the rope was considerably longer than was necessary, and they sank many feet into the water, still retaining their hold.

Then clinging to the rope they hauled themselves to the surface.
"We cannot hold on here five minutes," Ralph exclaimed, "my armour is dragging me down." "We will soon get rid of that," Walter said.
"There go our helmets; now I will hold on with one hand and help you to unbuckle your breast and back pieces; you do the same for me." With great efforts they managed to rid themselves of their armour, and then held on with ease to the rope.

They hauled the bucket to the surface and tied a knot in the slack of the rope, so that the bucket hung four feet below the level of the water.

Putting their feet in this, they were able to stand with their heads above the surface without difficulty.
"This is a nice fix," Ralph exclaimed.
