"And it was because of all this that the bacteriologists had so little chance in fighting the germs. They were killed in their laboratories even as they studied the germ of the Scarlet Death. They were heroes. As fast as they perished, others stepped forth and took their places. It was in London that they first isolated it. The news was telegraphed everywhere. Trask was the name of the man who succeeded in this, but within thirty hours he was dead. Then came the struggle in all the laboratories to find something that would kill the plague germs. All drugs failed. You see, the problem was to get a drug, or serum, that would kill the germs in the body and not kill the body. They tried to fight it with other germs, to put into the body of a sick man germs that were the enemies of the plague germs--"

"And you can't see these germ-things, Granser," Hare-Lip objected, "and here you gabble, gabble, gabble about them as if they was anything, when they're nothing at all. Anything you can't see, ain't, that's what. Fighting things that ain't with things that ain't! They must have been all fools in them days. That's why they croaked. I ain't goin' to believe in such rot, I tell you that."

Granser promptly began to weep, while Edwin hotly took up his defense.

"Look here, Hare-Lip, you believe in lots of things you can't see." Hare-Lip shook his head.

"You believe in dead men walking about. You never seen one dead man walk about."

"I tell you I seen 'em, last winter, when I was wolf-hunting with dad."

"Well, you always spit when you cross running water," Edwin challenged.

"That's to keep off bad luck," was Hare-Lip's defence.

"You believe in bad luck?"

"Sure."

"An' you ain't never seen bad luck," Edwin concluded triumphantly.

"You're just as bad as Granser and his germs. You believe in what you don't see. Go on, Granser."
