e stepped over to a cabinet, poured a small quantity of
the liquid into a test tube and did some hurried experimenting.

"The regulation knockout drops," he smiled grimly. "Now, help
me to take off your friend's overcoat. Whew! There is the smell
of alcohol here!

"Only on the overcoat, I guess, doctor," suggested Dave. "You
don't notice any on my friend's breath, do you?

"No," replied the doctor.

"There has been a plot on foot to make it appear that my friend
had been indulging in liquor. Doctor, I hope you can prove positively
that such was not the case."

"I shall have to pump the young man's stomach out. That is the
first step in getting him back to consciousness. That will also
show convincingly whether he has been using alcoholic drinks."

Within three minutes Dr. Stewart was positive that Dan had not
been using strong drink.

Soon after Dan regained consciousness. Dr. Stewart quickly gave
him something to restore his faculties.

Catching sight of the office clock Dave broke in:

"Doctor, if it is barely possible, we must be back for supper

deep breaths as you can."

Dave, in the meantime, was standing near fan attending to driving
the fumes from his friend's coat.

A few minutes later Dr. Stewart gave Dalzell a third draught.
Dan was now recovering steadily from his mental numbness.

"You can take your friend away safely, now," declared Dr. Stewart,
at last. "He can thank a strong constitution for recovering so
quickly under treatment."

"Shall I take him near the gate in a cab, or walk him there?"
asked Darrin.

"It will bring about his recovery more completely if he walks."

"Pardon me for a moment, then, and I'll go outside and release
the driver."

Then, returning, Darrin added:

"Doctor, if you'll hand me your bill, Mr. Dalzell will
