The White Linen Nurse was so tired that her noble expression ached. Incidentally her head ached and her shoulders ached and her lungs ached and the ankle-bones of both feet ached quite excruciatingly. But nothing of her felt permanently incapaci-tated except her noble expression. Like a strip of lip-colored lead suspended from her poor little nose by two tugging wire-gray wrinkles her persistently conscientious sickroom smile seemed to be whanging aimlessly against her front teeth. The sensation certainly was very unpleasant. Looking back thus on the three spine-curving, chest-cramping, foot-twinging, ether-scented years of her hospital training, it dawned on the White Linen Nurse very suddenly that nothing of her ever had felt permanently incapacitated except her noble expression! Impulsively she sprang for the prim white mirror that capped her prim white bureau and stood staring up into her own entrancing, bright-colored Novia Scotian reflection with tense and unwonted interest. Except for the unmistakable smirk which fatigue had clawed into her plastic young mouth-lines there was certainly nothing special the matter with what she saw.
