In a few seconds the air came hissing into the helmet, showing that the two men who wrought it were equal to their duty, though inexperienced.

“All right?” asked Rooney a second time.

The reply was given, “Yes,” and the bull’s-eye was screwed on.

Rooney then sprang up the ladder and through the manhole; took his station at the signal-line and air-pipe, while the engineer of the works watched the air-pump. The rickety steam-engine was then stopped, and, as had been predicted, the water rose quickly. It rose over Baldwin’s knees, waist, and head, and, finally, rushed out at the manhole, deluging Rooney’s legs.

Our diver was now fairly imprisoned; an accident, however trifling in itself, that should stop the air-pump would have been his death-knell. Fully impressed with this uncomfortable assurance, he felt his way slowly down the second ladder, knocking his head slightly against cross-beams as he went, holding on tightly to his bag and hammer, and getting down into darkness so profound as to be “felt.” He soon reached the head of the third ladder, and then the fourth.

But here, at a depth of about thirty feet, an unexpected difficulty

occurred which had well-nigh caused a failure. The head of the fourth ladder was covered with wood, through which a square manhole led to the bottom of the well. Of course Joe Baldwin discovered this only by touch, and great was his anxiety when, passing his hand round it, he found the hole to be too small for his broad shoulders to pass. At this point, he afterwards admitted, he “felt rather curious,” the whole structure being very frail. However, with characteristic determination he muttered to himself, “never mind, Joe, do it if you can,” and down he went through the hole, putting one arm down with his body, and holding the other up and drawing it down after him, by which process he squeezed his shoulders through at an angle. After reaching the bottom of the well, a feeling of alarm seized him lest he should be unable to force his way upwards through the hole. To settle this question at once he ascended to it, forced himself through, and then, being easy in mind, he redescended to the bottom and went to work with the hammer and wooden pegs.

At first he had some difficulty in finding the holes in the great cylinder, but after a dozen of them had been plugged it became easier, as the water rushed in through the remaining holes with greater force. While thus engaged his foot suddenly slipped. To save himself from falling—he knew not whither—he let go the bag of pegs and the hammer—the first of which went upwards and the latter down. To find the hammer in total darkness among the brick-work at the bottom was hopeless, therefore Joe signalled that he was coming up, and started for the top after the bag, but failed to find it. In much perplexity he went to the upper manhole and put up one of his hands.

To those who were inexperienced it was somewhat alarming to see the hand of an apparently drowning man with the fingers wriggling violently, but Rooney understood matters.
