The round eyes of childhood typify innocence; the narrowed line of the flirt's optic proves the invasion of art. The horizontal mouth is the mark of determined cunning; who has not read Nature's most spontaneous lyric in lips rounded for the candid kiss? Beauty is Nature in perfection; circularity is its chief attribute. Behold the full moon, the enchanting golf ball, the domes of splendid temples, the huckleberry pie, the wedding ring, the circus ring, the ring for the waiter, and the "round" of drinks. On the other hand, straight lines show that Nature has been deflected. Imagine Venus's girdle transformed into a "straight front"! When we begin to move in straight lines and turn sharp corners our natures begin to change. The consequence is that Nature, being more adaptive than Art, tries to conform to its sterner regulations. The result is often a rather curious product--for instance: A prize chrysanthemum, wood alcohol whiskey, a Republican Missouri, cauliflower _au gratin_, and a New Yorker. Nature is lost quickest in a big city. The cause is geometrical, not moral. The straight lines of its streets and architecture, the rectangularity of its laws and social customs, the undeviating pavements, the hard, severe, depressing, uncompromising rules of all its ways--even of its recreation and sports--coldly exhibit a sneering defiance of the curved line of Nature. Wherefore, it may be said that the big city has demonstrated the problem of squaring the circle. And it may be added that this mathematical introduction precedes an account of the fate of a Kentucky feud that was imported to the city that has a habit of making its importations conform to its angles. The feud began in the Cumberland Mountains between the Folwell and the Harkness families. The first victim of the homespun vendetta was a 'possum dog belonging to Bill Harkness. The Harkness family evened up this dire loss by laying out the chief of the Folwell clan. The Folwells were prompt at repartee. They oiled up their squirrel rifles and made it feasible for Bill Harkness to follow his dog to a land where the 'possums come down when treed without the stroke of an ax. The feud flourished for forty years. Harknesses were shot at the plough, through their lamp-lit cabin windows, coming from camp-meeting, asleep, in duello, sober and otherwise, singly and in family groups, prepared and unprepared. Folwells had the branches of their family tree lopped off in similar ways, as the traditions of their country prescribed and authorized. By and by the pruning left but a single member of each family. And then Cal Harkness, probably reasoning that further pursuance of the controversy would give a too decided personal flavour to the feud, suddenly disappeared from the relieved Cumberlands, baulking the avenging hand of Sam, the ultimate opposing Folwell.
