Farther back in the gloom stood a strange-looking air-pump; while in various directions, coiled and trailed like snakes, great lengths of india-rubber tubing, apparently in disorder, but really carefully kept ready for instant use, this being Rasp's special task, of which he was proud to a degree. "This is a teaser," said Dutch to himself, after making sundry lines on the paper before him, and then pausing, compasses in one hand, pen in the other. "Valve A to close tube B--escape-valve at A dash--small copper globe at B dash, as a reservoir, and--hum--ha--yes--to be sure, small stop-cock in the middle of the copper tube at H. That's it! I've got it at last." "Of course you have--I knew you would," said a short quick voice. Dutch started, and turned sharply round, to confront the little, square-built man who had entered the office quietly, and stood peering over his shoulder. "Ah, Mr Parkley! I didn't hear you come in," said Dutch, smiling. "Too busy over your work," said the new-comer, who seemed all hat and comforter, from between which peered a pair of keen, restless eyes. "I knew you'd work that out, Dutch, or else I shouldn't have given you the job. Dutch Pugh, I'd give something for your cleverness with pen and pencil. Look at me, sir, a man dragged up instead of brought up--a man who never signs his name because he can't write decently--a man who can hardly read a newspaper, unless the type's big. Ignorant, ignorant to a degree--a man--" "Of sound judgment, sir," said Dutch, interrupting him, "who from the power of his brain and long experience has suggested more improvements in hydraulic machinery than any of our greatest scientists, and who has not only originated and made his great business, but whose opinion is sought from everywhere in all great diving cases." "Stuff--stuff--stuff, Dutch! I'm ashamed of my ignorance." "And who is one of the wealthiest men in Ramwich." "Gammon and flattery, Dutch, my lad," said the other, taking off his great hat to place it jauntily on one of the diving-helmets, and then returning into the light, with his broad bald head shining, and his dark, restless eyes twinkling good-humouredly. "Here, catch hold of that," he continued, thrusting one hand into his chest, and dragging out the fringed end of his white woollen comforter. Dutch Pugh laid down his compasses, smiling, and took hold of the end of the comforter, when its wearer began slowly to turn round before the fire, as if he was being roasted, unwinding about three yards of comforter from his neck, and then giving a sigh of relief as he again went into the back part of the office, and hung the woollen wrap round one of the diver's necks. "I've managed to make bread and cheese, Pugh--bread and cheese," he said, chuckling, as he came back, climbed upon a stool by that of his assistant, and sat with his hands on his knees. "Yes, bread and cheese; beef and horse-radish. Pugh, how's the little wife?"
