But Cleek stood there at the window with his hands in his trousers' pockets, humming a little tune and watching this amazing phenomenon which a whole village had believed to be witchcraft, as though the thing surprised him not one whit; as though, in fact, he was a trifle amused at it. Which indeed he was.
Finally he swung round upon his heels and looked at each of the faces in turn, his own broadening into a grin, his eyes expressing incredulity, wonderment, and lastly mirth. At length he spoke:
"Gad!" he ejaculated with a little whistle of astonishment. "You mean to tell me that a whole township has been hanging by the heels, so to speak, upon as ridiculously easy an affair as that?" He jerked his thumb outward toward the flames and threw back his head with a laugh. "Where is your 'general knowledge' which you learnt at school, man? Didn't they teach you any? What amazes me most is that there are others—forgive me—equally as ignorant. Want to know what those flames are, eh?"
"Well, rather!"
"Well, well, just to think that you've actually been losing sleep on it! Shows what asses we human beings are, doesn't it? No offence meant, of course. As for you, Mr. Narkom—or Mr. Gregory Lake, as I must remember to call you for the good of the cause—I'm ashamed of you, I am indeed! You ought to know better, a man of your years!"
"But the flames, Cleek, the flames!" There was a tension in Merriton's voice that spoke of nerves near to the breaking point. Instantly Cleek was serious. He reached out a hand and laid it upon the young man's shoulder. Merriton was trembling, but he steadied under the grip, just as it was meant that he should.
"See here," Cleek said, bluntly, "you oughtn't to work yourself up into such a state. It's not good for you; you'll go all to pieces one of these days. Those flames, eh? Why I thought any one knew enough about natural phenomena to answer that question. But it seems I'm wrong. Those flames are nothing more nor less than marsh gas, Sir Nigel, evolved from the decomposition of vegetation, and therefore only found in swampy regions such as this. Whew! and to think that here is a community that has been bowing down to these things as symbols from another world!"
"Marsh gas, Mr.—"
"Headland, please. It is wiser, and will help better to remember when the necessity arises," returned Cleek, with a smile. "Yes, that is all they are—the outcome of marsh gas."
"But what is marsh gas, Mr.—Headland?" Merriton's voice was still strained.
