ither and thither
seeking his victims. Here he would take the husband from the wife, here
the child from its mother, here the statesman from his duty, and here the
toiler from his trouble. He would follow the water-mains, creeping along
streets, picking out and punishing a house here and a house there where
they did not boil their drinking-water, creeping into the wells of the
mineral water makers, getting washed into salad, and lying dormant in
ices. He would wait ready to be drunk in the horse-troughs, and by unwary
children in the public fountains. He would soak into the soil, to reappear
in springs and wells at a thousand unexpected places. Once start him at
the water supply, and before we could ring him in, and catch him again,
he would have decimated the metropolis."
He stopped abruptly. He had been told rhetoric was his weakness.
"But he is quite safe here, you know--quite safe."
The pale-faced man nodded. His eyes shone. He cleared his throat. "These
Anarchist--rascals," said he, "are fools, blind fools--to use bombs when
this kind of thing is attainable. I think----"
A gentle rap, a mere light touch of the finger-nails, was heard at the
door. The Bacteriologist opened if. "Just a minute, dear," whispered his
wife.
When he re-entered the laboratory his visitor was looking at his watch. "I
had no idea I had wasted an hour of your time," he said. "Twelve minutes
to four. I ought to have left here by half-past three. But your things
were really too interesting. No, positively I cannot stop a moment longer.
I have an engagement at four."
He passed out of the room reiterating his thanks, and the Bacteriologist
accompanied him to the door, and then returned thoughtfully along the
passage to his laboratory. He was musing on the ethnology of his visitor.
Certainly the man was not a Teutonic type nor a common Latin one. "A
morbid product, anyhow, I am afraid," said the Bacteriologist to himself.
"How he gloated over those cultivations of disease germs!" A disturbing
thought struck him. He turned to the bench by the vapour bath, and then
very quickly to his writing-table. Then he felt hastily in his pockets and
then rushed to the door. "I may have put it down on the hall table," he
said.
"Minnie!" he shouted hoarsely in the hall.
"Yes, dear," came a remote voice.
"Had I anything in my hand when I spoke to you, dear, just now?"
