We might almost look upon the nature-spirits as a kind )f astral humanity, but for the fact that none of them—not ;ven the highest—possesses a permanent reincarnating ndividuality. Apparently, therefore, one point in which their line of evolution differs from ours is that a much greater proportion of intelligence is developed before permanent individualization takes place ; but of the stages through which they have passed, and those through which they have yet to pass, we can know little. The life-periods of the different subdivisions vary greatly, some being quite short, others much longer than our human lifetime. We stand so entirely outside such a life as theirs that it is impossible for us to understand much about its conditions; but it appears on the whole to be a simple, joyous, irresponsible kind of existence, much such as a party of happy children might lead among exceptionally favourable physical surroundings.
