MARY. I think WE may, perhaps, manage it; but I cannot at all understand how the crystals do. It seems to imply so much preconcerting of plan, and so much giving way to each other, as if they really were living. L. Yes, it implies both the concurrence and compromise, regulating all wilfulness of design: and, more curious still, the crystals do NOT always give way to each other. They show exactly the same varieties of temper that human creatures might. Sometimes they yield the required place with perfect grace and courtesy; forming fantastic, but exquisitely finished groups: and sometimes they will not yield at all; but fight furiously for their places, losing all shape and honor, and even their own likeness, in the contest. MARY. But is not that wholly wonderful? How is it that one never sees it spoken of in books? L. The scientific men are all busy in determining the constant laws under which the struggle takes place; these indefinite humors of the elements are of no interest to them. And unscientific people rarely give themselves the trouble of thinking at all, when they look at stones. Not that it is of much use to think; the more one thinks, the more one is puzzled. MARY. Surely it is more wonderful than anything in botany? L. Everything has its own wonders; but, given the nature of the plant, it is easier to understand what a flower will do, and why it does it, than, given anything we as yet know of stone-nature, to understand what a crystal will do, and why it does it. You at once admit a kind of volition and choice, in the flower; but we are not accustomed to attribute anything of the kind to the crystal. Yet there is, in reality, more likeness to some conditions of human feeling among stones than among plants. There is a far greater difference between kindly-tempered and ill- tempered crystals of the same mineral, than between any two specimens of the same flower: and the friendships and wars of crystals depend more definitely and curiously on their varieties of disposition, than any associations of flowers. Here, for instance, is a good garnet, living with good mica; one rich red, and the other silver white; the mica leaves exactly room enough for the garnet to crystallize comfortably in; and the garnet lives happily in its little white house; fitted to it, like a pholas in its cell. But here are wicked garnets living with wicked mica. See what ruin they make of each other! You cannot tell which is which; the garnets look like dull red stains on the crumbling stone. By the way, I never could understand, if St. Gothard is a real saint, why he can't keep his garnets in better order. These are all under his care; but I suppose there are too many of them for him to look after. The streets of Airolo are paved with them. MAY. Paved with garnets?
