becomes the evidence that a uniform plan links every form in manifold
nature."

The great scientist pointed to another Bose instrument.

"I will show you experiments on a piece of tin. The life-force in
metals responds adversely or beneficially to stimuli. Ink markings
will register the various reactions."

Deeply engrossed, I watched the graph which recorded the characteristic
waves of atomic structure. When the professor applied chloroform
to the tin, the vibratory writings stopped. They recommenced as
the metal slowly regained its normal state. My companion dispensed
a poisonous chemical. Simultaneous with the quivering end of the
tin, the needle dramatically wrote on the chart a death-notice.

"Bose instruments have demonstrated that metals, such as the steel
used in scissors and machinery, are subject to fatigue, and regain
efficiency by periodic rest. The life-pulse in metals is seriously
harmed or even extinguished through the application of electric
currents or heavy pressure."

I looked around the room at the numerous inventions, eloquent
testimony of a tireless ingenuity.

"Sir, it is lamentable that mass agricultural development is
not speeded by fuller use of your marvelous mechanisms. Would it
not be easily possible to employ some of them in quick laboratory
experiments to indicate the influence of various types of fertilizers
on plant growth?"
