n us to understand that he had this power you describe?" asked
Captain Parkinson.

"In his grasp. Then comes a practical gentleman with a steel hook. A
follower of dreams, too, in his way. Conflicting interests--you know how
it is. One well-aimed blow from the more practical dreamer, and the
greater vision passes.... I'm getting ahead of myself. Just a moment."

His cigarette glowed fiercely in the dimness before he took up his tale
again.

"You all know who Dr. Schermerhorn was. None of you know--I don't know
myself, though I've been his factotum for ten years--along how many varied
lines of activity that mind played. One of them was the secret of energy:
concentrated, resistless energy. Man's contrivances were too puny for him.
The most powerful engines he regarded as toys. For a time high explosives
claimed his attention. He wanted to harness them. Once he got to the point
of practical experiment. You can see the ruins yet: a hole in southern New
Jersey. Nobody ever understood how he escaped. But there he was on his
feet across a ten-foot fence in a ploughed field--yes, he flew the fence--
and running, running furiously in the opposite direction, when the dust
cleared away. Someone stopped him finally. Told him the danger was over.
'Yet, I will not return,' he said firmly, and fainted away. That disgusted
him with high explosives. What secrets he discovered he gave to the
government. They were not without value, I believe."

"They were not, indeed," corroborated Barnett.

"Next his interest turned to the natural phenomena of high energy. He
studied lightning in an open steel network laboratory, with few results
save a succession of rheumatic attacks, and an improved electric
interrupter, since adopted by one of the great telegraph companies. The
former obliged him to stop these experiments, and the invention he
considered trivial. Probably the great problem of getting at the secret of
energy led him into his attempts to study the mysterious electrical waves
radiated by lightning flashes; at any rate he was soon as deep into the
subject of electrical science as his countryman, Hertz, had ever been. He
used to tell me that he often wondered why he hadn't taken up this line
before--the world of energy he now set out to explore, waves in that
tremendous range between those we hear and those we see. It was natural
that he should then come to the most prominent radio-active elements,
uranium, thorium, and radium. But t
