Rooney was a man of contrivance and resource. He soon fitted the pump to the new dress and found that it worked well, though the helmet was destitute of the modern regulating valves under the diver’s control, and he knew that it must needs therefore leave the diver who should use it very much at the mercy of the men who worked the pumps.

After the fire, Rooney removed with his family to the house of a Chinese labourer named Chok-foo, whose brother, Ram-stam, dwelt with him. They were both honest hard-working men, but Chok-foo was beginning, as we have seen, to fall under the baleful influence of opium-smoking. Ram-stam may be said to have been a teetotaler in this respect. They were both men of humble spirit.

Chok-foo took the destruction of his pipe and the rough collaring that followed in good part, protesting, in an extraordinary jargon, which is styled Pidgin-English, that he had only meant to have a “Very littee smokee,” not being able, just then, to resist the temptation.

“Blathers!” said Rooney, as they walked along in the direction of the lower part of the town, “you could resist the timptation aisy av you’d only try, for you’re only beginnin’, an’ it hasn’t got howld of ’ee yit. Look at your brother Ram, now; why don’t ’ee take example by him?”

“Yis, Ram-stam’s first-chop boy,” said Chok-foo, with a penitential expression on his fat visage.

“Well, then, you try and be a first-chop boy too, Chok, an’ it’ll be better for you. Now, you see, you’ve kep’ us all waiting for full half an hour, though we was so anxious to try how the dress answers.”

In a few minutes the son of Erin and the Chinaman entered the half ruinous pagoda which was their habitation. Here little Mrs Machowl was on her knees before an air-pump, oiling and rubbing up its parts. Ram-stam, with clasped hands, head a little on one side, and a gentle smile of approbation on his lips, admired the progress of the operation.

“Now then, Chok and Ram,” said Rooney, sitting down on a stool and making the two men stand before him like a small awkward squad, “I’m goin’ to taich you about pumps an’ pumpin’, so pay attintion av ye plaze. Hids up an’ ears on full cock! Now then.”

Here the vigorous diver began an elaborate explanation which we will spare the reader, and which his pupils evidently did not comprehend, though they smiled with ineffable sweetness and listened with close attention. When, however, the teacher descended from theory to practice, and took the pump to pieces, put it up again, and showed the manner of working, the Chinamen became more intelligent, and soon showed that they could turn the handles with great vigour. They were hopelessly stupid, however, in regard to the use of the signal-line—insomuch that Rooney began to despair.

“Niver mind, boys,” he cried, hopefully, “we’ll try it.”
