A model in suggestions for elementary teaching is offered in _California Plants in their Homes_,[19] by _Alice Merritt Davidson_, formerly of the State Normal School, California. The book consists of two parts, a botanical reader for children and a supplement for the use of teachers, both divisions being also published in separate volumes. It is well illustrated, provided with an index and an outline of lessons adapted to different grades. The treatment of each theme is fresh, and the grouping novel, as is indicated by the chapter headings: Some Plants that lead Easy Lives, Plants that know how to meet Hard Times, Plants that do not make their own Living, Plants with Mechanical Genius. Although specially designed for the study of the flora of southern California, embodying the results of ten years' observation by the author, it may be recommended to science teachers in any locality as an excellent guide. The pupil in this vicinity will have to forego personal inspection of the shooting-star and mariposa lily, while he finds the century plant, yuccas, and cacti domiciled in the greenhouse. In addition to these, however, attention is directed to a sufficient number of familiar flowers, trees, ferns, and fungi for profitable study, and the young novice in botany can scarcely make a better beginning than in company with this skillful instructor.
