result of accidental discovery. Until man pondered over such simple
facts and coördinated them so that he could extend his knowledge by
general reasoning, his progress could not be rapid. But the sluggish
mind of primitive man is capable of devising improvements, however
slowly, and the art of making fire by means of rubbing fire-sticks
gradually became more refined. Mechanical improvements resulted from
experience, with the consequence that finally one stick was rubbed to
and fro in a groove, or was rapidly twirled between the palms of the
hands while one end was pressed firmly into a hole in a piece of wood.
In the course of a few seconds or a minute, depending upon skill and
other conditions, a fire was obtained. It is interesting to note how
civilized man is often compelled by necessity to adopt the methods of
primitive beings. The rubbing of sticks is an emergency measure of the
master of woodcraft at the present time, and the production of fire in
this manner is the proud accomplishment or ambition of every Boy Scout.

Where only such crude means of kindling fire were available it became
the custom in some cases to maintain a fire burning continuously in a
public place. Around this pyrtaneum the various civil, political, and
religious affairs were carried on by the light and warmth of the public
fire. Many quaint customs evolved, apparently, from this ancient
procedure.

The tinder-box of modern centuries doubtless originated in very early
times, for it is inconceivable that the earliest beings did not become
aware of the production of sparks when certain stones were struck
together. In the stone age, when human beings spent much of their time
chiseling implements and utensils from stone by means of tools of the
same substance, it appears certain that this means of producing fire was
ever apparent. Many of their sharp implements, such as knives and
