This ought to be a pushover, in these days when Spanish is being introduced into public school curricula, when a working knowledge of Spanish is accepted as a sine qua non to sincere brotherly love between North and South America. For here, at last, is a self-teaching method, starting with simple conversations, in which, progressively, a vocabulary is built so naturally that the sense (plus the illustrations which I've not seen) carries over without reference to the vocabulary at the end of the book. Then, after successive lessons along these lines, some elements of grammar are amplified, and simple composition or story telling is introduced, followed by more difficult reading. Again, a further elaboration of the elements of grammar, so that the working knowledge is put into a frame for further self-development. From an outsider's standpoint, it seems good.
