Mathematical recreations and essays . theloop. There are now two dorsal strings and one palmar string on the righthand. Third. P puts a similar loop on the left hand by bending it overoutside the radial string and up into the space between the hands. with the back of the right middle-finger takes up from the proximal side { below) the left palmar string. And then similarly with the back of theleft middle-finger takes up from the proximal side that part of the right palmar 352 STRING FIGURES [CH. XVIII string which lies across the base of the right middle-finger. The hands arenow drawn apart so as to make the strings taut. The figure known as Snuffer-Trays—^eo. figure ii—ie formedby six loops, three on each hand. Four of the strings crossdiamond-wise in the middle so as to form two side crosses andtwo end crosses, the other two strings are straight, one beingnear and the other far. All the strings lie in a horizontalplane. This figure is also known as Soldiers Bed, the GhurchWindow, and the Figure ii. Snuffer-Trays. Snuffer-Trays can be got from the Cradle thus. I suppose that the Cradleis held by one operator, P, and that the other operator, Q, faces P. inserts the thumb and index-finger of his left hand from his far side in thoseangles of the cross of the Cradle farthest from him which lie towards Ps Q inserts the thumb and index-finger of his right hand from his nearside in those angles of the cross nearest to him which lie towards Ps hands,both thumbs being towards Ps right hand, and his index-fingers towards Psleft hand. Second. Q takes hold of each cross by the tips of the thumb andfinger, then pulls each cross outwards { away from the centre of the figure)over and beyond the corresponding horizontal string, then down, and thenround the corresponding horizontal strings. Third. Q turns the thumbs andfingers upwards through a right angle, thus passing the cross up between thetwo horizontal strings. By t
