is such that the results, however varied, harmonize thoroughly with
indigenous textile forms.

To make these points quite clear it will be necessary to analyze
somewhat closely the character and scope of textile combination and of
the resultant and associated phenomena.

We may distinguish two broad classes of constructive phenomena made
use of in the expression of relieved enrichment. As indicated above,
these are, first, essential or actual constructive features and,
second, extra or superconstructive features.

First, it is found that in the practice of primitive textile art a
variety of methods of combination or bindings of the parts have been
evolved and utilized, and we observe that each of these--no matter
what the material or what the size and character of the filamental
elements--gives rise to distinct classes of surface effects. Thus it
appears that peoples who happen to discover and use like combinations
produce kindred decorative results, while those employing unlike
constructions achieve distinct classes of surface embellishment. These
constructive peculiarities have a pretty decided effect upon the style
of ornament, relieved or colored, and must be carefully considered in
the treatment of design; but it is found that each type of combination
has a greatly varied capacity of expression, tending to obliterate
sharp lines of demarkation between the groups of results. It sometimes
even happens that in distinct types of weaving almost identical
surface effects are produced.

It will not be necessary in this connection to present a full series
of the fundamental bindings or orders of combination, as a few will
