There is something highly refreshing in what we read 'about the kindergarten child (by which is meant the child of from three to seven years old). We gain a vivid impression of the wealth and activity which human nature exhibits when it un folds itself under favourable conditions, and of the many possibilities which it includes. But for the teacher and the educator, the problem is so much the greater if he is so to order his instruction and his education as to bring to perfection, and if possible to surpass, what nature thus offers spontaneously if, indeed, he is simply to avoid spoiling what has already unfolded itself. I am convinced that the indefatigable observer and enthusiastic educationist who has written these books will find comprehending and interested readers in other languages besides that of his Homeland.
