But on the whole, the teacher must be very expert, and must have extraordinary needs, to feel justified in going outside the established canon of fairy-tales for his material. For there is a canon more or less fixed, into which have entered those stories that have from long and perpetual use taken on a more or less acceptable form; stories from those nations whose culture has blended to produce the modern occidental tradition. The canon includes Grimm's tales, Perrault's _Mother Goose_ tales, a few of Madame d'Aulnoy's, a few Danish and Norwegian stories, some from Italian sources and through Italian media, some from the _Arabian Nights_, some unhesitatingly admitted lately from collections of English folk-tales made in our own day, two or three chapbook stories, a few interlopers like _The Three Bears_, _Goody Two Shoes_, and some of Andersen's--not popular tales at all, but having in them some mysterious charm that opened the door to them. One cannot attempt to fix the limits more narrowly, for he has no sooner closed the list than he realizes that every teacher who has used them, every mother who has read them to her little people, every boy or girl who loves them, will have some other tale to insert, some perfect thing not provided for in this tentative catalogue. Besides, from time to time there does appear a new claimant with every title to admission, such as some of the Irish tales told by Seumas McManus or Douglas Hyde, or certain of the Zuñi folk-tales collected by Cushing. But on the whole, may we not agree that the list indicated constitutes the authentic accepted canon of fairy-tales established and approved by the teachers and children of occidental tradition and rearing? Still, there are choices to be made among these folk-tales of the accepted list. No child should be told all of them. Practically all children do have too many fairy-tales told them, and suffer in this, as in most of the things supplied them, from the discouraging and confusing "too much." For a whole year in which the main stories are taken from the folk-tales, a half-dozen stories will be enough.
