everything!”
“That ain’t so,” Tubby muttered.
But now the lecturer was illustrating
his point. He had a little turn-table gadget that looked like the record turn-table of a
phonograph.
He put a small white cardboard pillbox
on it
“That box is held there by gravity,” he
said. “Now I will slowly rotate the table.”
The turn-table disc began to revolve
slowly. The pill-box stayed in its place.
“That’s the Earth and us on it,” the
lecturer said. “But now if the rotation is

The turn-table went faster. Presently

“Nothin’ could make me slide off the Earth.
I’m too heavy. That ain’t right.”
“But it is right!” a strange voice hissed
in his ear. “It’s right, and it’s vital! It’s illuminating. Oh, now I realize that it fits in exactly with all the terrible facts!”
A hand was gripping Tubby’s fat
shoulder—a long-fingered bony hand that
shook with excitement. Tubby turned and
stared into the face of the man behind him. It was a long, thin, bony face that looked like skin drawn over a skull.
The man’s eyes were blazing.
“You said you were too heavy to slide
off the Earth,” he addressed Tubby. “How
much do you weigh?”
“Me? Hun’erd an’ ninety-two pounds,”
Tubby said proudly. “More maybe.”
The cadaverous man gulped.
“You—you look it. Yes, you’re a little
safer than the rest of us, but not much.”
“Safer?” Tubby gasped. “What’s the
