I take up pen for this foreword with the fear of one who knows that he cannot do justice to his subject, and the trembling of one who would not, for a good deal, set down words unpleasing to the eye of him who wrote Green Mansions, The Purple Land, and all those other books which have meant so much to me. For of all living authors--now that Tolstoi has gone I could least dispense with W. H. Hudson. Why do I love his writing so? I think because he is, of living writers that I read, the rarest spirit, and has the clearest gift of conveying to me the nature of that spirit. Writers are to their readers little new worlds to be explored; and each traveller in the realms of literature must needs have a favourite hunting-ground, which, in his good will--or perhaps merely in his egoism--he would wish others to share with him.
