It is a difference in the traditions of propriety with respect to the kinds of things which may, without derogation to the consumer, be consumed under the head of objects of taste and art.

With a certain allowance for variations to be accounted for on other grounds, these traditions are determined, more or less rigidly, by the pecuniary plane of life of the class.
Everyday life affords many curious illustrations of the way in which the code of pecuniary beauty in articles of use varies from class to class, as well as of the way in which the conventional sense of beauty departs in its deliverances from the sense untutored by the requirements of pecuniary repute.

Such a fact is the lawn, or the close-cropped yard or park, which appeals so unaffectedly to the taste of the Western peoples.
It appears especially to appeal to the tastes of the well-to-do classes in those communities in which the dolicho-blond element predominates in an appreciable degree.

The lawn unquestionably has an element of sensuous beauty, simply as an object of apperception, and as such no doubt it appeals pretty directly to the eye of nearly all races and all classes; but it is, perhaps, more unquestionably beautiful to the eye of the dolicho-blond than to most other varieties of men.

This higher appreciation of a stretch of greensward in this ethnic element than in the other elements of the population, goes along with certain other features of the dolicho-blond temperament that indicate that this racial element had once been for a long time a pastoral people inhabiting a region with a humid climate.
