A good portion of the material in this volume was printed in serial form in _The Delineator_, to whose editors and publishers I am deeply indebted for the sympathy and encouragement that were necessary to bring my ideas on boy training into the circle of general parenthood. As a result of the publicity gained through the medium of that magazine’s wide circulation, many letters were received by the magazine and by myself; and in this mass of correspondence there was a distinct note of appeal for the publication of the essays between covers. It was quite without any knowledge of this demand, however, that the present publishers, acting independently, became interested in the series, and decided, after due consideration, to issue it in book form. It was surprising that of the many letters received while these articles were appearing serially, only a small minority of the writers disagreed with my views, and those few protests were confined to one or two subjects. So far as could be reasonably expected of one whose time is much occupied in pursuing a livelihood, I replied to all such communications. If in some instances I failed, the omission was not because I was lacking in a keen appreciation of the interest, the sympathy, the suggestions and the criticisms thus expressed. As to those who disagreed with me, I would like to repeat here what I have said to them in personal replies: They may be right, and I wrong. This much only, I know--That Providence is kind in that He permits me to retain a distinct picture of the boy’s cosmos; that as a man and a father I can still see--and feel--from the boy’s viewpoint; and that, preserving that visuality, I have tried, with the best judgment and most constant effort of which I am capable, to employ it for the greatest good. Everything that I have written about boy training is solidly fixed on this foundation; and everything that I have written has been or is being employed, to the very letter, in my stewardship of one who is infinitely more precious to me than life itself--my own boy. If I have erred, may God forgive me; but on this score my conscience is as clear as a crystal pool, for so far as human vision penetrates not one duty has been left undone and not one endeavour has gone astray. And happily, though I say it with a prayer on my lips and humility in my heart, every passing year adds its living testimony to the principles which I advocate and for which I plead. C. W. Bringing up the Boy I FROM BABY TO BOY Your son, madam, while passing a vacant house, paused, poised his arm and deliberately sent a small stone crashing through one of the windows. Then, turning on his heel, he ran nimbly up the street and disappeared around the corner.
