We are not contending that there is no difference whatever in the mental constitution of the two sexes. There may be less tendency to ratiocination in woman; there is certainly more of feeling, a quicker and more sensitive nature. One sees this especially in children. Mark them in their play-hours, in their holiday freedom, when they are left to themselves to find matter of enjoyment,--how much more pleasure does the girl evidently derive from any beautiful or living thing that comes before it than the boy! We have an instance of it almost as we write. There is a group of children on the beach. The little girl is in perfect ecstasies, as she looks at the sparkling waves that come bounding to her feet; she shouts, she leaps, she herself bounds towards them, then springs back as they approach, half frightened and half pleased--she knows not how to express her delight at this great playfellow she has found. Meanwhile the boy, her brother, does nothing but throw stones at it--of that he seems never wearied. The beach is a perfect armoury to him, and he pelts the graceful waves remorselessly. What is their grace to him? So, too, in an inland scene, a garden or a lawn, we have often noticed what exquisite pleasure a little girl will feel, as she watches a sparrow alight near her upon the ground, in search of crumbs or other food. Her little frame quite thrills as this other little piece of life comes hopping and pecking about her. She loads it, but with suppressed voice, with all the endearing epithets her vocabulary supplies. She is evidently embarrassed that they are so few: she makes up by their frequent repetition. She absolutely _loves_ the little creature, with all whose movements she seems to have the keenest sympathy. Her brother, the boy, he has nothing for it but his unfailing stone, or he flings his hat at it. Unfailing, fortunately, the stone is not; for, if his skill as a marksman responded to his destructive zeal, there is nothing that a stone would kill that would be left alive, or that a stone would break that would be left whole. A mere blind animal-activity seems, at that very interesting age, to distinguish the future lord of the creation.
