To put it quite clearly, it was exactly as though one line of rails had separated into two lines of rails, as often enough they do, and an observer standing on high ground between could see them both vanishing into tunnels to the right and left, but far apart.
The second notable thing was that the right-hand groove, where first we saw it at the point of separation, was not polished like the left-hand groove, although at some time or other it seemed to have been subjected to the pressure of the same terrific weight which cut its fellow out of the bed of rock or iron, as the sharp wheels of a heavily laden wagon sink ruts into a roadway.
"What does it all mean, Lord Oro ?" I asked when he had led us back to the spot where the one groove began to be two grooves, that is, a mile or so away from the razor-edged cliff.
"This, Humphrey," he answered.

"That which travels along yonder road, when it reaches this spot on which we stand, follows the left-hand path which is made bright with its passage.

Yet, could a giant at that moment of its touching this exact spot on which I lay my hand, thrust it with sufficient strength, it would leave the left-hand road and take the right-hand road." "And if it did, what then; Lord Oro ?" "Then within an hour or so, when it had travelled far enough upon its way, the balance of the earth would be changed, and great things would happen in the world above, as once they happened in bygone days.

Now do you understand, Humphrey ?" "Good Heavens! Yes, I understand now," I answered.

"But fortunately there is no such giant." Oro broke into a mocking laugh and his grey old face lit up with a fiendish exultation, as he cried: "Fool! I, Oro, am that giant.
