to illustrate this fact. Originally pins were
stuck upon a paper web by hand, and placed in
rows, equidistant from each other. This necessitates
the cooperative function of the fingers and
the eye. An expert pin sticker could thus assemble
from four to five thousand pins a day.

The first mechanical pinsticker placed over
500,000 pins a day on the web, rejecting every bent
or headless pin, and did the work with greater
accuracy than it was possible to do it by hand.
There was not the suggestion of an eye, or a finger
in the entire machine, to show that nature furnished
the type.

NATURE NOT THE GUIDE AS TO FORMS.--Nature
does not furnish a wheel in any of its mechanical
expressions. If man followed nature's form
in the building of the locomotive, it would move
along on four legs like an elephant. Curiously
enough, one of the first road wagons had "push
legs,"--an instance where the mechanic tried to
copy nature,--and failed.

THE PROPELLER TYPE.--The well known propeller
is a type of wheel which has no prototype in
nature. It is maintained that the tail of a fish
in its movement suggested the propeller, but the
latter is a long departure from it.
