“More like a piece falling somewhere inside—beneath our feet—and I distinctly heard a soft, echoing rumble.”

“Come along down, old man,” said Dickenson. “It’s too hot to be up here, and if we stop any longer we shall have something worse than being hungry—a bad touch of the sun. I feel quite ready to go off my head and imagine all sorts of things. For instance, there’s a swimming before my eyes which makes me fancy I can see puffs of smoke rising out yonder, and a singing and cracking in my ears like distant firing.”

“Where?” cried Lennox excitedly. “Yes, of course. I can see the puffs plainly, and hear the faint cracking of the fire. Bob, my lad, then that sharp sound we heard must have been the reverberation of a gun.”

“Oh dear!” groaned Dickenson. “Come along down, and let’s get our heads in the cool stream and drink like fishes.”

“Don’t be foolish! Get out your glass.”

“To drink with?”

“No! Absurd! To watch the firing.”

“There is no firing, man,” cried Dickenson.

“There is, I tell you.”

“Oh, he has got it too,” groaned Dickenson. “Very well; all right—there is fighting going on out there a couple of miles away, and I can see the smoke and hear the cracking of the rifles. But come on down and let’s have a drink of water all the same; there’s plenty of that.”
