Thus we are reminded that all this loveliness, this exquisite beauty, is the work of natural selection--the result of the survival of favourable variations in the struggle for existence. These minute symmetrical forms, this wax-like texture, these marvellous rows of coloured, enamel-like encrustation, have been selected from almost endless and limitless possible variations, and have been accumulated and maintained there as they are in all their beauty, by survival of the fittest--by natural selection. All beauty of living things, it seems, is due to Nature's selection, and not only all beauty of colour and form, but that beauty of behaviour and excellence of inner quality which we call "goodness." The fittest, that which has survived and will survive in the struggle of organic growth, is (we see it in these flowers) in man's estimation the beautiful. Is it possible to doubt that just as we approve and delightedly revel in the beauty created by "natural selection," so we give our admiration and reverence, without question, to "goodness," which also is the creation of Nature's great unfolding? Goodness (shall we say virtue and high quality?) is, like beauty, the inevitable product of the struggle of living things, and is Nature's favourite no less than man's desire. When we know the ways of Nature, we shall discover the source and meaning of beauty, whether of body or of mind. As these thoughts are drifting through our enchanted dream we suddenly hear a deep and threatening roar from the mountain-side. We look up and see an avalanche falling down the rocks of the Jungfrau. The vast mountain, with its dazzling vestment of eternal snow, and its slowly creeping, green-fissured glaciers, towers above into the cloudless sky. In an instant the mind travels from the microscopic details of organic beauty, which but a moment ago held it entranced, to the contemplation of the gigantic and elemental force whose tremendous work is even now going on close to where we stand. The contrast, the range from the minute to the gigantic, is prodigious yet exhilarating, and strangely grateful. How many millions of years did it take to form those rocks (many of them are stratified, water-laid deposits) in the depths of the ocean? How many more to twist and bend them and raise them to their present height? And what inconceivably long persistence of the wear and tear of frost and snow and torrent has it required to excavate in their hard bosoms these deep, broad valleys thousands of feet below us, and to leave these strangely moulded mountain peaks still high above us? And that beauty of the sun-lit sky and of the billowy ice-field and of the colours of the lake below and of the luminous haze and the deep blue shade in the valley--how is that related to the beauty of the flowers? Truly enough, it is not a beauty called forth by natural selection. It is primordial; it is the beauty of great light itself. The response to its charm is felt by every
