emember that the key of an alarm clock turns as the alarm
works. That's all there is to it. Set the alarm when you want to wake
up--see--like this. Alarm goes off, winds up spring, throws weight off
balance, weight falls, shuts the window, opens the register and you
stay under the covers. Practical demonstration now proceeding."

The mechanism worked exactly as he had predicted. The Tennessee Shad
and the Wild Irishman, transfixed with awe, watched with dropped
mouths the operation. Finnegan, the first to recover, salaamed in true
Oriental fashion.

"Mr. Edison," he said in a whisper, "don't take advantage of two
innocent babes in the wood. Did you honestly just work this out?"

"Oh, no, of course not," said Dink loftily. "My father told me,--it
cost him a fortune; he gave years of his life to perfecting it!"

"And this to me!" said the exponent of the superlative reproachfully.

The Tennessee Shad rose and offered his hand with a gesture worthy of
Washington.

"Sir to you. I am your humble servant. Wonderful! Marvelous! Smashing!
Terrific! Sublime!"

"Do it again," said Dennis de Brian de Boru.

"What's wrong?"

"You would call in the whole House, would you?"

"Why not?" said Dink, thirsting for the applause of the multitude.

"Dink, oh, Dink!" said the Shad, in profound sorrow. "You would throw
away a secret worth millions, would you?"

Dink looked at Dennis, who returned the look, and then with a
simultaneous motion they sat down.

"This invention has millions in it, millions," said the Tennessee
Shad, promoter. "It is simple, but revolutionary. Every room in the
school must be equipped with it."

"Then there's all the apartment houses," said Dennis eagerly.

"That will come later," said the Tennessee Shad.

"We'll patent it," said Stover, seeing clouds of gold.

"Certainly," said the promoter. "We will patent the principle."

"Let's form a comp
