but the expression of a well-made man appears not only in his face ; it is in his limbs and joints also , it is curiously in the joints of his hips and wrists ; it is in his walk , the carriage of his neck , the flex of his waist and knees-dress does not hide him ; the strong , sweet supple quality he has , strikes through the cotton and flannel ; to see him pass conveys as much as the best poem , perhaps more ; you linger to see his back , and the back of his neck and shoulder-side .
