cotta, glass, concrete and plaster, none
of which materials are to be found in nature.

The untutored savage might cross a stream astride a floating tree trunk.
By and by it occurred to him to sit inside the log instead of on it, so
he hollowed it out with fire or flint. Later, much later, he constructed
an ocean liner.

Cain, or whoever it was first slew his brother man, made use of a stone
or stick. Afterward it was found a better weapon could be made by tying
the stone to the end of the stick, and as murder developed into a fine
art the stick was converted into the bow and this into the catapult and
finally into the cannon, while the stone was developed into the high
explosive projectile. The first music to soothe the savage breast was
the soughing of the wind through the trees. Then strings were stretched
across a crevice for the wind to play upon and there was the AEolian
harp. The second stage was entered when Hermes strung the tortoise shell
and plucked it with his fingers and when Athena, raising the wind from
her own lungs, forced it through a hollow reed. From these beginnings we
have the organ and the orchestra, producing such sounds as nothing in
nature can equal.

The first idol was doubtless a meteorite fallen from heaven or a
fulgurite or concretion picked up from the sand, bearing some slight
resemblance to a human being. Later man made gods in his own image, and
so sculpture and painting grew until now the creations of futuristic art
could be worshiped--if one wanted to--without violation of the second
commandment, for they are not the likeness of anything that is in heaven
above or that is in the earth beneath or that is in the water under the
earth.

In the textile industry the same development is observable. The
primitive man used the skins of animals he had slain to protect his own
skin. In the course of time he--or more probably his wife, for it is to
the women rather than to the men that we owe the early steps in the arts
and sciences--fastened leaves together or pounded out bark to make
garments. Later fibers were plucked from the sheepskin, the cocoon and
the cotton-ball, twisted together and woven into cloth. Nowadays it is
possible to make a complete suit of clothes, from hat to shoes, of any
desirable texture, form and color, and not include any substance to be
found in nature. The first metals available were those found free in
nature such as gold and copper. In a later age it was found
