ll listed and double-catalogued by name and by disease.

"Genuine. Provably genuine, every one. There's romance in some of 'em.
And gratitude; good Lord! Sometimes when I look 'em over, I wonder I
don't run for President of the United States on a Certina platform."

From the testimonial room they went to the art department where Dr.
Surtaine had some suggestions to make as to bill-board designs.

"You'll never get another puller like Old Lame-Boy," Hal heard the head
designer say with a chuckle, and his father reply: "If I could I'd start
another proprietary as big as Certina."

"Where does that lead to?" inquired Hal, as they approached a side
passage sloping slightly down, and barred by a steel door.

"The old building. The manufacturing department is over there."

"Compounding the medicine, you mean?"

"Yes. Bottling and shipping, too."

"Aren't we going through?"

"Why, yes: if you like. You won't find much to interest you, though."

Nor, to Hal's surprise, did Dr. Surtaine himself seem much concerned
with this phase of the business. Apparently his hand was not so close in
control here as in the other building. The men seemed to know him less
well.

"All this pretty well runs itself," he explained negligently.

"Don't you have to keep a check on the mixing, to make sure it's right?"

"Oh, they follow the formula. No chance for error."

They walked amidst chinking trucks, some filled with empty, some with

fortified odor underlying it, greeted the unaccustomed nose of the
neophyte.

"Good!" he sniffed. "How clean and appetizing it smells!"

Enthusiasm warmed the big man's voice once more.

"Just what it is, too!" he exclaimed. "Now you've hit on the second big
point in Certina's success. It's easy to take. What's the worst thing
about doctors' doses? They're nasty. The very thought of 'em would gag a
cat. Tell people that here's a remedy better than the old medicine and
pleasant to the taste, and they'll take to it like ducks to water.
Certina is the first proprietary that ever tasted good. Next to Old
Lame-Boy, it's my biggest idea."

"Are we going into the mixing-room?" asked his son.

"If you like. But you'll see
