These miracles are being worked all around us so easily and so cheaply that most people have ceased to think of them as marvels. There is a photographer established in every considerable village,--nay, one may not unfrequently see a photographic _ambulance_ standing at the wayside upon some vacant lot where it can squat unchallenged in the midst of burdock and plantain and apple-Peru, or making a long halt in the middle of a common by special permission of the "Selectmen." We must not forget the inestimable preciousness of the new Promethean gifts because they have become familiar. Think first of the privilege we all possess now of preserving the lineaments and looks of those dear to us. "Blest be the art which can immortalize," said Cowper. But remember how few painted portraits really give their subjects. Recollect those wandering Thugs of Art whose murderous doings with the brush used frequently to involve whole families; who passed from one country tavern to another, eating and painting their way,--feeding a week upon the landlord, another week upon the landlady, and two or three days apiece upon the children; as the walls of those hospitable edifices too frequently testify even to the present day. Then see what faithful memorials of those whom we love and would remember are put into our hands by the new art, with the most trifling expenditure of time and money. This new art is old enough already to have given us the portraits of infants who are now growing into adolescence. By-and-by it will show every aspect of life in the same individual, from the earliest week to the last year of senility. We are beginning to see what it will reveal. Children grow into beauty and out of it. The first line in the forehead, the first streak in the hair are chronicled without malice, but without extenuation. The footprints of thought, of passion, of purpose are all treasured in these fossilized shadows. Family-traits show themselves in early infancy, die out, and reappear. Flitting moods which have escaped one pencil of sunbeams are caught by another. Each new picture gives us a new aspect of our friend; we find he had not one face, but many. It is hardly too much to say, that those whom we love no longer leave us in dying, as they did of old. They remain with us just as they appeared in life; they look down upon us from our walls; they lie upon our tables; they rest upon our bosoms; nay, if we will, we may wear their portraits, like signet-rings, upon our fingers. Our own eyes lose the images pictured on them. Parents sometimes forget the faces of their own children in a separation of a year or two. But the unfading artificial retina which has looked upon them retains their impress, and a fresh sunbeam lays this on the living nerve as if it were radiated from the breathing shape. How these shadows last, and how their originals fade away!
