Nothing is more incomprehensible to girls than the love and admiration sometimes given to middle-aged women. They cannot understand it; and nothing but experience will ever make them understand it. In their eyes, a woman is out of the pale of personal affection altogether when she has once lost that shining gloss of youth, that exquisite freshness of skin and suppleness of limb, which to them, in the insolent plenitude of their unfaded beauty, constitute the chief claims to admiration of the one sex from the other. And yet they cannot conceal from themselves that the pretty maid of eighteen is often deserted for the handsome woman of forty, and that the patent witchery of their own youth and brilliant colouring goes for nothing against the mysterious charms of a mature siren. What can they say to such an anomaly? There is no good in going about the world disdainfully wondering how on earth a man could ever have taken up with such an antiquated creature!--suggestively asking their male friends what could he see in a woman of her age, old enough to be his mother? There the fact stands; and facts are stubborn things. The eligible suitor who has been coveted by more than one golden-haired girl has married a woman twenty years her senior, and the middle-aged siren has quietly carried off the prize which nymphs in their teens have frantically desired to win. What is the secret? How is it done? The world, even of silly girls, has got past any belief in spells and talismans, such as Charlemagne's mistress wore, and yet the man's fascination seems to them quite as miraculous and almost as unholy as if it had been brought about by the black art. But if they had any analytical power they would understand the _diablerie_ of the mature siren clearly enough; for it is not so difficult to understand when one puts one's mind to it.
