NOTHING is so wonderful in modern times as the marvelous communion and circulation of life. Thought and feeling in perpetual currents of living intercourse, literature, politics, books, visibly and invisibly, ebb and flow over the whole earth. Like the rain, they fall everywhere; like water, they find their own level, and if checked in one place reappear as fountains in another. Rock and clay are omnipotent to dam them back from themselves, by an omnipotence, which sends them as rivulets with fertilizing power elsewhere. This little book put forth with many misgivings as a bit of life, yet with some confidence that what came from life would touch the lives of others, has not belied that hope. Its reception as a text book for teachers over a large district in America, with the welcome it has received in the United States, bears witness to workers in fresh fields of labour finding it helpful to them in their work. So the writer commends it once more to all fellow-workers, who are able and willing to receive these fruits of his life.
