The citation of primitive examples is more to our purpose, and I select first two games in which bits of wood are employed in lieu of balls. One in the Holstein Klink- or Klischspiel. A chip of a peculiar shape is balanced on the end of a stake driven diagonally into the ground and then hit from below with a sort of club. The other is simpler still: it is called Porscheck in the game books.[243] A cigar-shaped bit of wood is so placed that one end is free, and a blow on this free end sends it whirling in the air. In Heidelberg, where this game is much cultivated, and is dignified by frequent contests, the man about to strike asks “Tenez?” whereupon his antagonist answers “Oui,” neither party having the slightest suspicion that they are speaking French—a proof of the power of tradition.[244] Similar games are played by children, one being accompanied by singing as the piece of wood or arrow is shot into the air, and Rochholz suspects that this is a survival of a religious ceremony symbolic of the flight of winter before the fiery darts of spring. If so, it is one of many games which originated in this way. But how did the religious custom arise? Does not tracing its origin lead us in a circle back to playful experimentation, as we found to be in all probability the case with the discovery and application of some musical instruments? It is most likely. (_c_) Rolling, Spinning, Shoving, and Skipping Foreign Bodies In this division I group together such plays as lend a special character to the movement of the object, including them all, however, in the general class of throwing play, since it would unnecessarily complicate matters to make a separate class of them. In all plays with rolling balls, such as tenpins and billiards, pleasure in motion as such forms the undercurrent of the satisfaction afforded, even when they develop into important contests. The thundering roll and crash of the heavy wooden ball, and the noiseless, lightning-quick motion of the elastic ivory one, each has its charm. In a billiard room it is amusing to note how irresistible is the impulse to most players to take the balls from their pockets and roll them on the green surface after the game is over. Primitive forms of such games no doubt originated in experimentation with the round or disc-shaped stones found in every river or brook bed. Many fruits, too, are used in the same way—the horse chestnut, for example, being a favourite plaything wherever it grows. Yet the manufacture of artificial balls is no doubt very ancient, but inquiry into that must not detain us here. After the first years of life, when rolling in itself is an object, such balls are used in relation to some goal, perhaps partly because they are constantly getting lost when knocked aimlessly about, and the children do not wish to risk their precious possessions.
