It was as the secretary of an old Charity Trust that Mr. Arthur Morrison first made his acquaintance with East London, and by dint of several years' residence and attentive study acquired his knowledge of the East End and its myriad denizens. Right in the midst of the great square bounded by the Thames, the Lea, the City, Kingsland, and the Hackney open spaces lie the dreary "Mean Streets" which Mr. Morrison has described with uncommon power and vigor, and among which the operations of his secretaryship engaged him laboriously for years. The possibility of presenting his observations of East London in narrative form began to grow upon him while casting around for literary pabulum to convert into magazine articles, and in October, 1891, appeared his first sketch, entitled "A Street," in "Macmillan's Magazine." This, in a remodelled form, now serves as an introductory chapter to the present collection. The article in "Macmillan's" attracted a good deal of attention, and won for its author the good fellowship of Mr. W. E. Henley, who encouraged him in his idea of writing a series of short stories and studies which should describe East End life with austerity, restraint, and frankness. A large number of the "Tales" appeared in the "National Observer" and several followed in the "Pall Mall Budget." The dedication to Mr. Henley of "Tales of Mean Streets" is a grateful acknowledgment by the author of the kindly and frank counsel of his friendly critic; whose criticism, it may be added, has been mainly directed towards the author's craftsmanship--his conceptions of the life he was portraying the critic was wise enough to let alone. Mr. Morrison has also been indebted on the side of art in fiction to Mr. Walter Besant, whom he met in the East End.
