ward which they were
falling, and reported quietly:

"We made a lot of distance, but not enough. Everything goes in, this
time."

He tore out the single remaining light-wire, leaving the car in darkness
save for the diffused light of his electric torch, and broke up the only
remaining motor. He then took his almost priceless Swiss watch, his
heavy signet ring, his scarf pin, and the cartridges from his pistol,
and added them to the collection. Flashing his lamp upon Perkins, he
relieved him of everything he had which contained copper.

"I think I have a few pennies in my pocketbook," suggested Dorothy.

"Get 'em," he directed briefly, and while she was gone he searched
Margaret, without result save for the cartridges in her pistol, as she
had no jewelry remaining after her imprisonment. Dorothy returned and
handed him everything she had found.

"I would like to keep this ring," she said slowly, pointing to a slender

He threw all the metal into the central chamber and the vessel gave a
tremendous lurch as the power was again applied. It was soon spent,

unmoved scientist, who struck him with the butt of his pistol as he
leaped, the mighty force of DuQuesne's blow crushing his skull like an
eggshell and throwing him backward to the opposite side of the vessel.
Margaret lay in her seat in a dead faint. Dorothy and DuQuesne looked at
each other in the feeble light of the torch. To the girl's amazement,
the man was as calm as though he were safe in his own house, and she
made a determined effort to hold herself together.

"What next, Doctor DuQuesne?"

"I don't know. We have a couple of days yet, at least. I'll have to
study awhile."

"In that time Dick will find us, I know."

"Even if they do find us in time, which I doubt, what good will it do?
