The string is then taken up similarly by theright hand. The hands are now drawn apart. This is called the * first position. 358 STRING FIGURES [CH. XVIII Next with the back of the index of the right hand take up from the proximalside ( from below) the left palmar string, and return : in these descriptionsthe word return is used to mean a return to the position occupied at thebeginning of the movement by the finger or fingers concerned. Then,similarly, with the back of the index of the left hand take up from the proximalside that part of the right palmar string which lies across the base of the rightindex, and return. The figure now consists of six loops on the thumb, index,and little-finger of each hand. The resulting figure, in a horizontal plane, isshown in the diagram, looking down at it from Opening A. Opening B. Opening B is obtained as above, save that, in the second partof the Opening, the right palmar string is taken up by the left index beforethe left palmar string is taken up by the right index. In most of the figuresdescribed below it is immaterial whether we begin with Opening A or Opening B. Movement T. There is also another movement which ismade in the construction of many of the figures and whichmay be described once for all. This movement is when we have on a finger two loops, one proximal andthe other distal, and the proximal loop is pulled up over the distal loop, thenover the tip of the finger, and then dropped on the palmar side. I term this theMovement T. A Door. The first example I will give is a Door—seefigure V—which comes from the Apache Red Indians. Itaffords a good introduction to the Oceanic Varieties, for it isone of the easiest figures to construct, as the movements aresimple and involve no skill in manip
