Mathematical recreations and essays . ing the thumb and index-finger of onehand in opposite angles of the cross, holding the cross with thethumb and finger, and then turning the plane containing thethumb and finger through one or two right angles. When oneplayer takes the strings from the other, it is assumed that hedraws his hands apart so as to keep the string stretched. The initial figure is termed the Cradle; from this we canproduce Snuffer-Trays. From Snuffer-Trays we can obtainforms known as a Pound-of-Candles, Cats-Eye, and Trellis-Bridge. From each of these forms again we can proceed invarious ways. I will describe first the figures produced whenthe string is taken off so as to lead successively from theCradle to Snuffer-Trays, Cats-Eye, and Fish-in-a-Dish. Thisis the normal sequence. The Cradle—see figure i—is formed by six loops, three oneach hand: there are two horizontal strings, one near and theother far, and two pairs of strings which cross one another,each cross being over one of the horizontal Figure i. The Cradle. The Cradle is produced thus. First. One of the operators, P, loops thestring over the four fingers of each hand, which are held upright, palm towardspalm, the near or radial string lying between the thumbs and index-fingers, andthe far or ulnar string beyond the little fingers. Second. P puts a second loopon the right hand by bending it over outside the radial string and up into 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.
