"I'd like to take a revolver, too," said the Very Young Man. "It might
come in awful handy."

"As I remember Rogers's description," said the Doctor thoughtfully, "the
trip out is more difficult than going down. We mustn't overlook
preparations for that; it is most imperative we should be careful."

"Say, talking about getting back," burst out the Very Young Man. "I'd
like to see that other drug work first. It would be pretty rotten to get
in there and have it go back on us, wouldn't it? Oh, golly!" The Very
Young Man sank back in his chair overcome by the picture he had conjured
up.

"I tried it," said the Doctor. "It works."

"I'd like to see it again with something different," said the Big
Business Man. "It can't do any harm." The Banker looked his protest, but
said nothing.

"What shall we try, a lizard?" suggested the Very Young Man. The Doctor
shrugged his shoulders.

"What'll we kill it with? Oh, I know." The Very Young Man picked up a
heavy metal paper-weight from the desk. "This'll do the trick, fine," he
added.

Then, laying the paper-weight carefully aside, he dipped up a spoonful
of water and offered it to the Doctor.

"Not that water this time," said the Doctor, shaking his head with a
smile.

The Very Young Man looked blank.

"Organisms in it," the Doctor explained briefly. "All right for them to

and come out at us, do we?"

"Holy Smoke, I should say not," said the Very Young Man, gasping; and
the Banker growled:

"Something's going to happen to us, playing with fire like this."

The Doctor produced a little bottle. "I boiled this water," he said. "We
can use this."

It took but a moment to give the other drug to one of the remaining
lizards, although they spilled more of the water than went down its
throat.

"Don't forget to hit him, and don't you wait very long," said the Banker
warningly, moving nearer the door.

"Oh, I'll hit him all right, don't worry," said the Very Young Man,
brandishing the paper-weight.

The Doctor knelt down, and held the reptile pinned to the floor; the
Very Young Man knelt beside him. Slowly the lizard began to increase in
size.

"He's growing," said the Banker. "Hit him, boy, what's the use of
waiting; he's growing."

The lizard was nearly a foot long now, and struggling violently between
the Doctor's fingers.

"You'd better kill him," said the Doctor, "he might get away
