brought into use for the first time by more advanced races will never pass through the elementary stage of decoration, but will take its ornament greatly from existing art and carry this up in its own peculiar way through succeeding generations. The character of the ornamentation does not therefore depend upon the age of the art so much as upon the acquirements of the potter and his people in other arts.

ORIGIN OF FORM

In order to convey a clear idea of the bearing of the preceding statements upon the history of form and ornament, it will be necessary to present a number of points in greater detail.

The following synopsis will give a connected view of various possible origins of form.

FORMS SUGGESTED BY ADVENTITION.

The suggestions of accident, especially in the early stages of art, are often adopted, and become fruitful sources of improvement and progress. By such means the use of clay was discovered and the ceramic art came into existence. The accidental indentation of a mass of clay by the foot, or hand, or by a fruit-shell, or stone, while serving as an auxiliary in some simple art, may have suggested the making of a cup, the simplest form of vessel.

The use of clay as a cement in repairing utensils, in protecting combustible vessels from injury by fire, or in building up the walls of shallow vessels, may also have led to the formation of disks or cups, afterwards independently constructed. In any case the objects or utensils with which the clay was associated in its earliest use would impress their forms upon it. Thus, if clay were used in deepening or mending vessels of stone by a given people, it would, when used independently by that people, tend to assume shapes suggested by stone vessels. The same may be said of its use in connection with wood and wicker, or with vessels of other materials. Forms of vessels so derived may be said to have an adventitious origin, yet they are essentially copies, although not so by design, and may as readily be placed under the succeeding head.

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.

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.

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,
