+FORMS DERIVED BY IMITATION.+ 
Clay has no inherent qualities of a nature to impose a given form or 
class of forms upon its products, as have wood, bark, bone, or stone. It 
is so mobile as to be quite free to take form from surroundings, and 
where extensively used will record or echo a vast deal of nature and of
coexistent art. 
In this observation we have a key that will unlock many of the 
mysteries of form. 
In the investigation of this point it will be necessary to consider the 
processes by which an art inherits or acquires the forms of another art 
or of nature, and how one material imposes its peculiarities upon 
another material. In early stages of culture the processes of art are 
closely akin to those of nature, the human agent hardly ranking as more 
than a part of the environment. The primitive artist does not proceed by 
methods identical with our own. He does not deliberately and freely 
examine all departments of nature or art and select for models those 
things most convenient or most agreeable to fancy; neither does he 
experiment with the view of inventing new forms. What he attempts 
depends almost absolutely upon what happens to be suggested by 
preceding forms, and so narrow and so direct are the processes of his 
mind that, knowing his resources, we could closely predict his results. 
The range of models in the ceramic art is at first very limited, and 
includes only those utensils devoted to the particular use to which the 
clay vessels are to be applied; later, closely-associated objects and 
utensils are copied. In the first stages of art, when the savage makes a 
weapon, he modifies or copies a weapon; when he makes a vessel, he 
modifies or copies a vessel. 
This law holds good in an inverse ratio to culture, varying to a certain 
extent with the character of the material used. 
Natural originals.--Natural originals, both animal and vegetable, 
necessarily differ with the country and the climate, thus giving rise to 
individual characters in art forms often extremely persistent and 
surviving decided changes of environment. 
The gourd is probably the most varied and suggestive natural vessel. 
We find that the primitive potter has often copied it in the most literal 
manner. One example only, out of the many available ones, is 
necessary. This is from a mound in southeastern Missouri.
In Fig. 464, a illustrates a common form of the gourd, while b 
represents the imitation in clay.

gourd.] 
All nations situated upon the sea or upon large rivers use shells of 
mollusks, which, without modification, make excellent receptacles for 
water and food. Imitations of these are often found among the products 
of the potter's art. A good example from the Mississippi Valley is 
shown in Fig. 465, a being the original and b the copy in clay. 
In Africa, and in other countries, such natural objects as cocoanut shells, 
and ostrich eggs are used in like manner. 
Another class of vessels, those made from the skins, bladders, and 
stomachs of animals, should also be mentioned in this connection, as it 
is certain that their influence has frequently been felt in the 
conformation of earthen utensils. 
In searching nature, therefore, for originals of primitive ceramic forms 
we have little need of going outside of objects that in their natural or 
slightly altered state are available for vessels.

shell.] 
True, other objects have been copied. We find a multitude of the higher 
natural forms, both animal and vegetable, embodied in vessels of clay, 
but their presence is indicative of a somewhat advanced stage of art, 
when the copying of vessels that were functionally proper antecedents 
had given rise to a familiarity with the use of clay and a capacity in 
handling it that, with advancing culture, brought all nature within the 
reach of the potter and made it assist in the processes of variation and 
development. 
Artificial originals.--There is no doubt that among most peoples art had 
produced vessels in other materials antecedent to the utilization of clay.
These would be legitimate models for the potter and we may therefore 
expect to find them repeated in earthenware. In this way the art has 
acquired a multitude of new forms, some of which may be natural 
forms at second hand, that is to say, with modifications imposed upon 
them by the material in which they were first shaped. But all materials 
other than clay are exceedingly intractable, and impress their own 
characters so decidedly upon forms produced in them that ultimate 
originals, where there are such, cannot often be traced through them. 
It will be most interesting to note the influence of these
