“But what form of work could you devise which would employ so vast a number for so long a time, and yet not compete with any existing industry? To do the latter would simply mean to shift the misery from one class to another.”
“Precisely so. I should compete with no one. What I thought of doing was of sinking a shaft through the earth's crust, and of establishing rapid communication with the Antipodes. When you had got a certain distance down—how far is an interesting mathematical problem—the centre of gravity would be beneath you, presuming that your boring was not quite directed towards the centre, and you could then lay down rails and tunnel as if you were on the level.”
Then for the first time it flashed into Robert McIntyre's head that his father's chance words were correct, and that he was in the presence of a madman. His great wealth had clearly turned his brain, and made him a monomaniac. He nodded indulgently, as when one humours a child.
“It would be very nice,” he said. “I have heard, however, that the interior of the earth is molten, and your workmen would need to be Salamanders.”
“The latest scientific data do not bear out the idea that the earth is so hot,” answered Raffles Haw. “It is certain that the increased temperature in coal mines depends upon the barometric pressure. There are gases in the earth which may be ignited, and there are combustible materials as we see in the volcanoes; but if we came across anything of the sort in our borings, we could turn a river or two down the shaft, and get the better of it in that fashion.”
“It would be rather awkward if the other end of your shaft came out under the Pacific Ocean,” said Robert, choking down his inclination to laugh.
“I have had estimates and calculations from the first living engineers—French, English, and American. The point of exit of the tunnel could be calculated to the yard. That portfolio in the corner is full of sections, plans, and diagrams. I have agents employed in buying up land, and if all goes well, we may get to work in the autumn. That is one device which may produce results. Another is canal-cutting.”
“Ah, there you would compete with the railways.”
“You don't quite understand. I intend to cut canals through every neck of land where such a convenience would facilitate commerce. Such a scheme, when unaccompanied by any toll upon vessels, would, I think, be a very judicious way of helping the human race.”
“And where, pray, would you cut the canals?” asked Robert.
