"If you must drink water," said the Professor with authority, "have it
distilled."

"Jeeroosalem!" exclaimed Dan. "That's a gilt-edged idea. Perfessor,
ye're a pathologist, ain't yer?"

The Professor nodded. Genius, however exalted, acknowledges
unsolicited testimonials from any source. He saw plainly that in Dan's
eyes he loomed gigantic.

"I am," he replied graciously.

"A path-finder, a seeker-out of noo tracks to knowledge?"

"You might express it worse," said the Professor. "What can I do for
you?"

"I'm a mighty sick man," said Dan solemnly.

The Professor was so astonished that he nearly bit through his
excellent cigar; but at once a flame sparkled in his grey eyes. If
Dan, with his appearance of robust health, was really a mighty sick
man, why, then, his case challenged attention. He stood up and, so to
speak, spread his wings, hovering over his lawful prey.

"What's wrong?" he demanded.

"I'm afire with itching. At this moment I feel as if some dev'lish

"Oceans!"

"My poor fellow, I am distressed beyond words. I promise you that you
shall have every care and attention. I won't leave this ranch till--

that you ought to put your house in order."

"Hav'n't got no house," said Dan, not quite comprehending, but sadly
frightened. "Me and Mame expected to build next year, but that's off."

"Next year!" echoed the Professor testily. "The question is: Where
will you be next week?"

Dan staggered. The Professor, having long retired from active
practice, remembered with a qualm that he might have broken this
appalling news more considerately. He said quietly--

"I beg your pardon. I ought to have tempered this; but you are an
American, and strong enough at this moment to know the truth. I may
pull you through. Without boasting, there is not another man in
America, or Europe either, who would say as much."

"Christopher Columbus!"

"I don't call myself that," said the Professor modestly, "but I may
claim to have discovered pathogenic continents. Now, my boy"--he took
hold firmly of Dan's arm--"I am g
