In'like manner, in going through this book of mine after so many years I am amused at the way it is colored by the little cults and crazes, and modes of thought of the 'eighties of the last century. They were so important then, and now, if remembered at all, they appear so trivial! It pleases me to be diverted in this way at A Crystal Age — to find, in fact, that I have not stood still while the world has been moving. This criticism refers to the case, the habit, of the book rather than to its spirit, since when we write we do, as the red man thought, impart something of our souls to the paper, and it is probable that if I were to write a new dream of the future it would, though in some respects very different from this, still be a dream and picture of the human race in its forest period.
