The editor hopes that he has allotted a proportionate and equitable amount of space and emphasis to each type, department, and section of the collection. He had it in mind, at least, to give as many pages over to poetry, for example, in proportion to prose, as many pages to fairy stories, for example, in proportion to myths, as would indicate roughly the average child's interests. If this proportion is not due and just, as the editor sometimes fears, it is to be hoped that critics will realize the web of difficulties in which such a task as this is entangled. A word as to the classification and nomenclature. The editor realizes that this is neither original nor accurate. It is certainly not scientific, as the types overlap here and there, and the names are based partly on form and partly on content. But classification and class names were indispensable in a book of this nature, and it seemed a better policy to employ the classification and the names already firmly established in common use than to attempt to subject to a new system of scientific terms that which is by nature not amenable to scientific laws and scientific precision. The classification appears only in the Contents; it does not stand forth in the book itself. It should be said, further, that the order in which the different types are placed in the book is more or less arbitrary, having been determined largely by the succession in which children take them up from year to year, beginning with the simpler forms and more childish themes, and somewhat by the principle of similarity and contrast in the types themselves. Needless to say, teachers will change the order in which the species and specimens are studied in accordance with any well-defined plan of their own. A distinct service has been rendered, the editor hopes, by presenting the definitive and authoritative versions of all the selections given. This has meant a painstaking reading of every line in every selection and the collation with editions that are trustworthy. Every student of children's literature knows that it has been almost impossible to find exact readings, and that most selections have been distorted and garbled to suit the purposes of editors. No changes from the originals have here been made except to abridge in a few instances where it seemed imperative in a book intended for reading and discussion in classes of both sexes. The editions used and the changes made are given in the Notes. The problems involved in selecting the best versions of certain stories and the best translations from other languages have been difficult. In general, the editor endeavored to choose the form which seemed to have the highest literary value. In cases where two translations seemed to possess equal merit, both are represented.
