It was a look so intelligent, yet inexplicable, perverse, sometimes so malicious, but generally accompanied by a wild flow of spirits, that Hester could not help questioning at such moments whether Pearl was a human child. She seemed rather an airy sprite, which, after playing its fantastic sports for a little while upon the cottage floor, would flit away with a mocking smile. Whenever that look appeared in her wild, bright, deeply black eyes, it invested her with a strange remoteness and intangibility: it was as if she were hovering in the air, and might vanish, like a glimmering light that comes we know not whence and goes we know not whither. Beholding it, Hester was constrained to rush towards the child--to pursue the little elf in the flight which she invariably began--to snatch her to her bosom with a close pressure and earnest kisses--not so much from overflowing love as to assure herself that Pearl was flesh and blood, and not utterly delusive. But Pearl's laugh, when she was caught, though full of merriment and music, made her mother more doubtful than before.

     Heart-smitten at this bewildering and baffling spell, that so often came between herself and her sole treasure, whom she had bought so dear, and who was all her world, Hester sometimes burst into passionate tears. Then, perhaps--for there was no foreseeing how it might affect her--Pearl would frown, and clench her little fist, and harden her small features into a stern, unsympathising look of discontent. Not seldom she would laugh anew, and louder than before, like a thing incapable and unintelligent of human sorrow. Or--but this more rarely happened--she would be convulsed with rage of grief and sob out her love for her mother in broken words, and seem intent on proving that she had a heart by breaking it. Yet Hester was hardly safe in confiding herself to that gusty tenderness: it passed as suddenly as it came. Brooding over all these matters, the mother felt like one who has evoked a spirit, but, by some irregularity in the process of conjuration, has failed to win the master-word that should control this new and incomprehensible intelligence. Her only real comfort was when the child lay in the placidity of sleep. Then she was sure of her, and tasted hours of quiet, sad, delicious happiness; until--perhaps with that perverse expression glimmering from beneath her opening lids--little Pearl awoke!
