The happiness of a perfect marriage, which enhances the vitality of the private life, renders one not only capable of adding to the stream of the life-blood of the community in children, but by marriage one is also rendered a fitter and more perfect instrument for one's own particular work, the results of which should be shared by society as a whole, and in the tempering and finishing of which society plays a part. Thus it is the concern of the whole community that marriage should be as perfect, and hence as joyous, as possible; so that the powers which should be set free and created for the purpose of the whole community should not be frittered away in the useless longing and disappointment engendered by ignorance, narrow restrictions, and low ideals. In the world the happily mated pair should be like a great and beautiful light; a light not hid under a bushel, but one whose beams shine through the lives of all around them. Chapter XI. The Glorious Unfolding Let knowledge grow from more to more, but more of reverence in us dwell. TENNYSON. We are surrounded in this world by processes and transmutations so amazing that were they not taking place around us hourly they would be scouted as impossible imaginings. A mind must be dull and essentially lacking in wonderment which, without amazement, can learn for the first time that the air we breathe, apparently so uniform in its invisible unity, is in reality composed of two principal, and several other, gases. The two gases, however, are but mixed as wine may be with water, and each gas by itself is a colourless air, visually like that mixture of the two which we call the atmosphere. Much greater is the miracle of the composition of water. It is made of only two gases, one of them a component of the air we breathe, and the other similarly invisible and odourless, but far lighter. These two invisible gases, when linked in a proportion proper to their natures, fuse and are no longer ethereal and invisible, but precipitate in a new substance--water. The waves of the sea with their thundering power, the sparkling tides of the river buoying the ships, are but the transmuted resultants of the union of two invisible gases. And this, in its simplest terms, is a parable of the infinitely complex and amazing transmutations of married love. Ellis expresses the strange mystery of one of the physical sides of love when he says:
