In the pursuit of this class of enrichment there is occasionally noticeable a tendency to overload the subject with extraneous details. This is not apt to occur, however, in the indigenous practice of an art, but comes more frequently from a loss of equilibrium or balance in motives or desires, caused by untoward exotic influence. When, through suggestions derived from contact with civilized art, the savage undertakes to secure all the grace and complexity observed in the works of more cultured peoples, he does so at the expense of construction and adaptability to use. An example of such work is presented in Fig. 290, a weak, useless, and wholly vicious piece of basketry. Other equally meretricious pieces represent goblets, bottles, and tea pots. They are the work of the Indians of the northwest coast and are executed in the neatest possible manner, bearing evidence of the existence of cultivated taste. [Illustration: FIG. 290. Basket made under foreign influence, construction and use being sacrificed to fancied beauty--1/3.] It appears from the preceding analyses that _form_ in this art is not sufficiently sensitive to receive impressions readily from the delicate touch of esthetic fingers; besides, there are peculiar difficulties in the way of detecting traces of the presence and supervision of taste. The inherent morphologic forces of the art are strong and stubborn and tend to produce the precise classes of results that we, at this stage of culture, are inclined to attribute to esthetic influence. If, in the making of a vessel, the demands of use are fully satisfied, if construction is perfect of its kind, if materials are uniformly suitable, and if models are not absolutely bad, it follows that the result must necessarily possess in a high degree those very attributes that all agree are pleasing to the eye. In a primitive water vessel function gives a full outline, as capacity is a prime consideration; convenience of use calls for a narrow neck and a conical base; construction and materials unite to impose certain limitations to curves and their combinations, from which the artist cannot readily free himself. Models furnished by nature, as they are usually graceful, do not interfere with the preceding agencies, and all these forces united tend to give symmetry, grace, and the unity that belongs to simplicity. Taste which is in a formative state can but fall in with these tendencies of the art, and must be led by them, and led in a measure corresponding to their persistency and universality. If the textile art had been the only one known to man, ideas of the esthetic in shape would have been in a great measure formed through that art. Natural forms would have had little to do with it except through models furnished directly to and utilized by the art, for the ideas of primitive men concentrate about that upon which their hands work and upon which their thoughts from necessity dwell with steady attention from generation to generation.
