    loose fly-piece over which the lacing passes. Cut D 13 illustrates the lee: applied. . If the end of the stump is small and has no prominences on the side the socket and core of the foot, which are integrally one piece, are carved from a block of wood the grain of which curves on the line of greatest strains. When the end of the stump is large and it is desired to incase it in a socket of minimum thickness, aluminum must be employed for reasons given. , Partially End-Bearing.—If only a part of the weight oi the wearer can be borne on the end of the stump the top of the socket must be made annular and fitted so that it will impinge against the sloping part of the leg below the knee. Cuts D 14 and D 16 Cut D 14. Cut D 15. illustrate suitable legs for the same and Cuts D 15 and D 17 show them applied. It is obvious that a stump, being inserted from the top of the socket of either, will not enter further than the top of the socket will permit, and this is just far enough to limit x pressure on the end or to avoid it altogether. When pressure can be taken on the end, it is regulated by the thickness of the pad placed in the bottom of the socket on which the end of the stump rests. A socket that admits the stump from the front, as in Cuts D 12 and D 14, is objectionable when the end of the stump is very large. The material necessary for strength is on the sides of the stump and increases the diameter of the ankle. It also affords but little
