At the request of the author, I have read this book in proof sheets, and, from the point of view of one interested in psychology, I have suggested many amendments which have all, I think, been adopted.

As will be seen by the intelligent reader, the best sleep involves more than a normal body; it involves healthy thought and the application to our daily lives of the moral principles laid down by our great spiritual teachers.

The cure of sleeplessness has hitherto been left largely to the physician, who is not always a specialist on that subject and who will welcome a treatise that will enable his patient to co-operate with his restorative measures. Mr. Hall has already shown in Three Acres and Liberty and in The Garden Yard his ability to put into clear, popular language and readable form scientific truths that non-scientific people need to know and wish to learn.

The proper management of our own bodies is even more essential to our happiness and well-being than the proper management of the land, and I hope that this book will be no less welcome to students and physicians than to the great mass who for lack of knowledge or of attention do not wholly avail themselves of the freely offered gift of sleep.

The book may be useful to many who find it difficult to harmonize their lives with their surroundings, and may bring to many a happier view of the ways of God to man.
