That, I suppose, is the best argument on the other side, and if you look straight at it for six seconds, you will see it dissolve like a lump of sugar in a tumbler of water and disappear under your very eyes. For the fact remains that when I listen to the receding footsteps of my little charmer, the sigh that escapes me expresses something of relief as well as regret. The signs of change have perhaps not yet appeared, and I wish not to see them. Good-bye, little one, we part in good time, and may we never meet again! Undoubtedly one loses something, but it cannot balance the gain. The loss in any case was bound to come, and had I waited for it no gain would have been possible. As it is, I am like that man in _The Pilgrim's Progress_, by some accounted mad, who the more he cast away the more he had. And the way of it is this; by losing my little charmers before they cease from charming, I make them mine for always, in a sense. They are made mine because my mind (other minds, too) is made that way. That which I see with delight I continue to see when it is no more there, and will go on seeing to the end: at all events I fail to detect any sign of decay or fading in these mind pictures. There are people with money who collect gems--diamonds, rubies and other precious stones--who value their treasures as their best possessions, and take them out from time to time to examine and gloat over them. These things are trash to me compared with the shining, fadeless images in my mind, which are my treasures and best possessions. But the bright and beauteous images of the little girl charmers would not have been mine if instead of letting the originals disappear from my ken I had kept them too long in it. All because our minds, our memories are made like that. If we see a thing once, or several times, we see it ever after as we first saw it; if we go on seeing it every day or every week for years and years, we do not register a countless series of new distinct impressions, recording all its changes: the new impressions fall upon and obliterate the others, and it is like a series of photographs, not arranged side by side for future inspection, but in a pile, the top one alone remaining visible. Looking at this insipid face you would not believe, if told, that once upon a time it was beautiful to you and had a great charm. The early impressions are lost, the charm forgotten.
