Today a divergence in ideals is beginning to be apparent. The portion of the leisure class that has been consistently exempt from work and from pecuniary cares for a generation or more is now large enough to form and sustain opinion in matters of taste. Increased mobility of the members has also added to the facility with which a "social confirmation" can be attained within the class. Within this select class the exemption from thrift is a matter so commonplace as to have lost much of its utility as a basis of pecuniary decency. Therefore the latter-day upper-class canons of taste do not so consistently insist on an unremitting demonstration of expensiveness and a strict exclusion of the appearance of thrift. So, a predilection for the rustic and the "natural" in parks and grounds makes its appearance on these higher social and intellectual levels. This predilection is in large part an outcropping of the instinct of workmanship; and it works out its results with varying degrees of consistency. It is seldom altogether unaffected, and at times it shades off into something not widely different from that make-believe of rusticity which has been referred to above. A weakness for crudely serviceable contrivances that pointedly suggest immediate and wasteless use is present even in the middle-class tastes; but it is there kept well in hand under the unbroken dominance of the canon of reputable futility. Consequently it works out in a variety of ways and means for shamming serviceability--in such contrivances as rustic fences, bridges, bowers, pavilions, and the like decorative features. An expression of this affectation of serviceability, at what is perhaps its widest divergence from the first promptings of the sense of economic beauty, is afforded by the cast-iron rustic fence and trellis or by a circuitous drive laid across level ground. The select leisure class has outgrown the use of these pseudo-serviceable variants of pecuniary beauty, at least at some points. But the taste of the more recent accessions to the leisure class proper and of the middle and lower classes still requires a pecuniary beauty to supplement the aesthetic beauty, even in those objects which are primarily admired for the beauty that belongs to them as natural growths.
