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 from me." The Very Young Man obediently brought his weapon down with a thump upon the reptile's head.

"Keep on," said the Banker. "Be sure he's dead."

The Very Young Man pounded the quivering body for a moment. The Big Business Man handed him a napkin from the tray and the Very Young Man wrapped up the lizard and threw it into the waste-basket.

Then he rose to his feet and tossed the paper-weight on to the desk with a crash.
