attering the blessings
of Certina amongst a grateful proletariat?"

"Not exactly. I'm down here on some other business."

"Well, I won't keep you from it, Dr. Surtaine. Good-bye."

The swinging doors of a saloon opened almost upon her, and a short,
broad-shouldered foreigner, in a ruffled-up silk hat, bumped into her
lightly and apologized. He jogged up to Dr. Surtaine.

"Hello, De Vito," said Dr. Surtaine.

"At the service of my distinguish' confrere," said the squat Italian.
"Am I require at the factory?"

"No. I've come to look into this sickness. Where is it?"

"The opposite eemediate block."

Dr. Surtaine eyed with disfavor the festering tenement indicated. "New
cases?"

"Two, only."

"Who's treating them?"

"Nobody knows he is owner. And it pays twelve per cent," said the
Italian mildly. He paused at the door. "Do we go in?" he asked.

An acrid-soft odor as of primordial slime subtly intruded upon the
sensory nerves of the visitor. The place breathed out decay; the decay
of humanity, of cleanliness, of the honest decencies of life turned
foul. Something lethal exhaled from that dim doorway. There was a stab
of pestilence, reaching for the brain. But the old charlatan was no
coward.

"Show me the cases," he said.

For an hour he moved through the black, stenchful passageways, up and
down ramshackle stairs, from human warren to human warren, pausing here
to question, there to peer and sniff and poke with an exploring cane.
Out on the street again he drew full, heaving breath.

"O'Farrell's got to clean up. That's all there is to that," he said
decisively.
