Figure 213 represents the rather angular and monotonous chip carving motive. It is, however, a simple form of carved enrichment for wood construction. Figure 214 shows the more rhythmic flow of a carved and modeled enrichment. Two methods of leaf treatment are given at _A_ and _B_.
Figures 215, 216, and 217 are industrial and public school examples of the forms of surface enrichment treated in this chapter.
Plate 35 shows the necessary working drawings for wood inlay and is supplied as a typical high school problem by Mr. C.E. Partch of Des Moines, Iowa. See Figure 216c.
(_a_) Draw the primary rectangle, appendage, etc.
(_b_) Subdivide the rectangle into its horizontal and vertical subdivisions.
(_c_) Design very simple contour enrichment.
(_d_) Determine the location of zone of enrichment, and the amount and method of enriching the surface.
(_e_) Make several preliminary sketches to determine the best design and add the one finally selected to the structure. Correlate with contour enrichment.
(_f_) Add additional views, dimension, and otherwise prepare the drawing for shop use.
Design a walnut side table 3 feet high and enrich with a double band inlay of ebony.
SUMMARY OF RULES Rule 6a. _Surfaces to be enriched must admit of enrichment._
Rule 6b. _Surface enrichment must be related to the structural contours but must not obscure the actual structure._
Rule 6c. _The treatment must be appropriate to the material._
Rule 6d. _Bands and borders should have a consistent lateral, that is, onward movement._
Rule 6e. _Bands and borders should never have a prominent contrary motion, opposed to the main forward movement._
Rule 6f. _All component parts of a border should move in unison with the main movement of the border._
Rule 6g. _Each component part of a border should be strongly dynamic and, if possible, partake of the main movement of the border._
Rule 6h. _Borders intended for vertical surfaces may have a strongly upward movement in addition to the lateral movement, provided the lateral movement dominates._
Rule 6i. _Inlayed enrichment should never form strong or glaring contrasts with the parent surface._
Rule 6j. _Carved surface enrichment should have the appearance of belonging to the parent mass._
