This figure has been found in Northern Europe, Africa, America, Oceania and Northern Asia. Every- where it is used to illustrate a story. The figure may be made thus : (1) Hold the left hand open with the palm facing you, and the thumb upright and the fingers pointing to the right and slightly upwards. With the right hand, loop the string over the left thumb, crossing the strings if you like, and let one string hang down over the palm and the other over the back of the hand—we may call these the palmar and dorsal strings. (2) Pass the right index-finger from below under the palmar string, and then between the left thumb and index-finger, and with its front tip hook up a loop of the dorsal string; pull this loop between the left thumb and index-finger back on to the left palm; then with the right index-finger give the loop one twist clockwise, and put it over the palmar string on to the left index-finger; pull the two pendant strings so as to tighten the loops on the thumb and index-finger. (3) In the same way pass the right index-finger from below under the.
