Josh, who had been the first to oppose the descent, was now the first to help, by seizing the back lead left upon the barrel head, and, with cat-like agility, leaping to the ladder and going down to the swimmer.

A dozen voices were shouting words of advice to Will, but the lad paid no heed; he merely drew himself up on the ladder, saw that the life-line was slack, and, clasping the leaden back-piece with both hands, with the life-line running loosely between his arms to act as a guide, he once more plunged into the sea, the weight seeming to take him down with tremendous force.

One instant the ponderous lead struck the water, the next there was a confused foam on the surface, and Will was gone.

The moments that followed seemed prolonged to hours. There was an indistinct movement visible in the disturbed water; the bubbles of air seemed to be lashing up more fiercely as the life-line was drawn rapidly through the hands that held it, and then, once more, Will’s head appeared, and he swam towards the ladder.

He could not speak, but made a sign with one hand.

“Haul!” cried Josh; “haul away!” as he reached out, caught Will’s arm, and drew him to the ladder; holding him up, for he was utterly exhausted, and could hardly get his breath.

And there they stayed while the line was hauled up, and the diver once more appeared above the surface; the poor fellow being hoisted on deck and his helmet rapidly unfastened and removed.

The men looked helplessly from one to the other as they lifted their eyes from the blackened countenance that one of the lighter’s men was supporting on his arm. No one seemed to know what would be best to do, and a couple were ordered into the boat to row ashore for the doctor.

“Why don’t you take off them gashly things?” cried Josh, who had now helped Will to the deck, where he stood holding on by a stay, trembling in every limb.

Two men immediately began to take off the heavy india-rubber diving suit, with its copper collar and heavy leaden-soled boots, with the result that when the poor fellow was freed from these encumbrances and once more laid upon the dock, the lifting and moving he had received proved so far beneficial that he uttered a low sigh, and the purple tinge began to die out from his face.
