eyes and clasping
his hand on his brow with a tragic gesture. He was suddenly taken
by the collar and shaken violently, and left more dazed than ever.
"Don't be a fool," said the Voice.

"I'm--off--my--blooming--chump," said Mr. Marvel. "It's no good.
It's fretting about them blarsted boots. I'm off my blessed blooming
chump. Or it's spirits."

"Neither one thing nor the other," said the Voice. "Listen!"

"Chump," said Mr. Marvel.

"One minute," said the Voice, penetratingly, tremulous with
self-control.

"Well?" said Mr. Thomas Marvel, with a strange feeling of having
been dug in the chest by a finger.

"You think I'm just imagination? Just imagination?"

"What else _can_ you be?" said Mr. Thomas Marvel, rubbing the back of
his neck.

"Very well," said the Voice, in a tone of relief. "Then I'm going
to throw flints at you till you think differently."

"But where _are_ yer?"

The Voice made no answer. Whizz came a flint, apparently out of
the air, and missed Mr. Marvel's shoulder by a hair's-breadth.
Mr. Marvel, turning, saw a flint jerk up into the air, trace a
complicated path, hang for a moment, and then fling at his feet
with almost invisible rapidity. He was too amazed to dodge. Whizz

"_Now_," said the Voice, as a third stone curved upward and hung in
the air above the tramp. "Am I imagination?"

Mr. Marvel by way of reply struggled to his feet, and was
immediately rolled over again. He lay quiet for a moment. "If you
struggle any more," said the Voice, "I shall throw the flint at
your head."

"It's a fair do," said Mr. Thomas Marvel, sitting up, taking his
wounded toe in hand and fixing his eye on the third missile. "I
don't understand it. Stones flinging themselves. Stones talking.
Put yourself down. Rot away. I'm done."

The third flint fell.

"It's very simple," said the Voice. "I'm an invisible man."

"Tell us something I don't know," said Mr. Marvel, gasping with
pain. "Where you've hid--how you do it--I _don't_ know. I'm beat."

"That's all," said the Voice. "I'm invisible. That's what I want
you to understand."

"Anyone could see that. There is no need for you to be so confounded
impatient, mister. _Now_ then. Give us a notion. How are you hid?"

"I'm invisible. That'
