The above points of approach to surface enrichment represent a logical reasoning process which supplies a line of sequential and developmental pictures that will reduce to a minimum the element of doubt and fog through which the average designer approaches his problem. The steps will, in time, become practically automatic and may be thought out in a surprisingly short period of time.

Rule 11c. The type of design unit for large masses should be bolder than similar designs for small primary masses.

Large Masses and Their Treatment

As may be expected from briefly considering the illustrations for this chapter as compared with those for small primary masses, [Chapter XIII], it is seen that the units for base and precious metals are larger and bolder than those used for smaller masses. The more effective designs are those whose appropriateness, simplicity, and correct structural proportions and relations appeal to our sense of fitness and beauty.

[Figures 403], [404], and [406] are composed of projects designed mainly on vertical inceptive axes or center lines. The freely balanced natural units in [Figure 403] have the zone of enrichment in the upper portion of the appendage (handles), and the point of concentration in the upper portion of the zone of enrichment. Formal symmetrical balance controls the placing of enrichment in [Figure 404]. Initial letters, through lack of consideration of design principles, are frequently misplaced on masses with little or no consideration given to their mass relations with the structural contours. As a contrast to this, notice the carefully considered relations between the letter W on the tea strainer in [Figure 404] and its adaptation to the contours of the appendage. The stone enrichment on the handle of the paper cutter in [Figure 404] in no way interferes with its use as a cutter and is therefore appropriate as surface enrichment.
