rce my
request. If you are at all doubtful, call up the Attorney General and
ask him."

The warden hesitated.

"If you don't mind, I think I will call Washington, Doctor," he said.
"I will have to get authority to turn No. 9764 over to you in any
event."

"Call all you wish, Mr. Lawson. Mr. Carnes is talking to Washington
now and we'll have a clear line through for you in a few minutes.
Meanwhile, get a set of shackles on Karuska and get him ready to
travel by plane. He appears to be suffering from mental paralysis, but
I don't know how his case will develope. He may go violently insane at
any moment and I don't care to be aloft in a plane with an unbound
maniac."

Major Martin looked up from the prone figure of Karuska.

"His condition duplicates that of Lieutenant Breslau, Dr. Bird," he
said. "We received your telephoned message this afternoon and we kept
Breslau in a flood of sunlight until dusk, and then put him under
sun-ray lamps. I don't know how you got on to that treatment, but it
is having a very beneficial effect. He can already make inarticulate
sounds, and his eyes are not quite as vacant at they were. If he keeps
on improving as he has, he should be able to talk intelligently in a
few days. If you wish to question this man, why not give him the same
treatment?"

"I haven't time, Major. I must make him talk to-night if it is humanly
possible. I called you in because you are the most eminent authority
on the brain in the government service. Is there any way of
artificially stimulating this man's brain so that we can force the
secrets of his subconscious mind from him?"

The major sat for a moment in profound thought.

"There _is_ a way, Doctor," he said at length, "but it is a method
which I would not dare to use. By applying high frequency electrical
stimulations to the medulla oblongata, at the same time bathing the
cerebellum with ultra-violet, it might be done, but the chances are
that either death or insanity would result. I would not do it."

"Major Martin, this man is a reckless and dangerous international
criminal. If his gang carries out the plan which I fear they have
formed, the lives of thousands, yes, of millions, may pay for your
hesitation. I will assume full responsibility for the test if you will
make it, and I have the authority of the President of the United
States behind me."

"In that case, Doctor, I have no choice. The President
