"This old see-saw that Hardock and the engineer want us to have, of course."

"Well, can't you see how good it will be?"

"No, I can't, nor you neither."

"But don't you see it sends the men all down eighteen feet into the mine?"

"Of course I can. Never mind the men. Suppose it's me, and I step on.

It sends me down eighteen feet."

"Yes, at one stride, and then comes up again; can't you see that?"

"Of course, I can. It comes up again, and brings me up with it, ready to go down again. Why, it's no good. It will be only like a jolly old up-and-down."

Gwyn stared at his companion.

"What are you talking about?" he said, but in a less confident tone.

"You know, this gimcrack thing that was to do so much. Why the idea's all wrong. Don't you see?"

Gwyn stared at his companion again.

"Nonsense!" he cried, "it's all right. There'll be a man step on to it at every platform, and then down he'll go."

"Of course, and when he has gone down eighteen or twenty feet, up he'll come again. It sounds very pretty, but it's all a muddle. It's just like the story of the man who wanted to go to America, so he went up in a balloon and stayed there for hours and waited till the world had turned round enough, so as to come down in America."

"Oh, but this is all right; they explained it exactly to my father, and I saw it all plainly enough then: it was as clear as could be," said Gwyn, thoughtfully. "A man stepped on and went down."

"Yes, and the beam rose and he came up again."

Gwyn scratched his head and looked regularly puzzled, and the more he tried to see the plan clearly, the more confused he grew.

"Here, I can't make it out now," he said at last.

"Of course you can't, my lad; it's all wrong."

"But if it is, there will be a terrible loss."

"To be sure there will."

"Let's go and talk to my father about it."

"Or mine," said Joe.

"Our place is nearest, or perhaps father's in the office," cried Gwyn, excitedly. "Mind, I don't say you're right, because I seemed to see it all so clearly, though it has all turned misty and stupid like now."

"I know how it was," said Joe. "Sam Hardock had got the idea in his head, and he explained it all so that it seemed right; but it isn't, and the more I think about it, the more I wonder that no one saw what a muddle it was before."

"Gammon!" cried Gwyn, springing up, and the two lads started back toward the mine; but they were not destined to reach it then, for they had not gone above a hundred yards along by the edge of the cliff, when they came upon Dina.s.s seated with his back to a rock, smoking his pipe and gazing out to sea between his half-closed eyelids.

"Hallo!" shouted Gwyn; "what are you doing here?"

"Smoking," said the man, coolly.

"Well, I can see that," cried Gwyn. "How is it you are not at work?"

"'Cause a man can't go on for ever without stopping. Man aren't a clock, as only wants winding up once a week; must have rest sometimes."

"Well, you have the night for rest," said Gwyn, sharply.

"Sometimes," said Dina.s.s; "but I was working the pump all last night."

"Oh, then you're off work to-day?"

"That's so, young gentleman, and getting warm again in the sun. It was precious cold down there in the night, and I got wet right through to my backbone. I'm only just beginning to get a bit dried now."

"Look here, Ydoll," said Joe, sharply; "he'll have been talking to Sam Hardock about it, I know. Here, Tom Dina.s.s, what about that hobby up-and-down thing Sam Hardock wants to have in the mine?"

"'Stead of ladders? Well, what about it?"

"It's all nonsense, isn't it?"

"Well, I shouldn't call it nonsense," said the man, thoughtfully, as he took his pipe out of his mouth and sat thinking.

"What do you call it, then?" said Joe.

"Mellancolly, sir, that's what I call it--mellancolly."

"Because it won't work?" cried Joe.

"But it would work, wouldn't it?" said Gwyn.

"Oh, yes, sir, it would work," said the man, "because the engine would pump it up and down."

"Of course it would," said Joe; "but what's the use of having a thing that pumps up and down, unless it's to bring up water?"

"Ay, but this is a thing as pumps men up and down," said Dina.s.s.

"Gammon! It's impossible."

Dina.s.s looked at him in astonishment.

"No, it aren't," he said gruffly. "I've been pumped up and down one times enough, so I ought to know."

"You have?" said Gwyn, eagerly.

"Ay, over Redruth way."
