Of this series of Science Readers, Books I, II, and III are adapted to secondary grades comprising pupils who are in their third and fourth years of school work. Both the reading and the subject matter of Books IV, V, and VI are suitable for grammar grades. The lessons in Books IV, V, and VI contain lessons sufficiently full and definite to enable the teacher to find out both the matter and method for the preliminary lessons, whenever such are needed. All the lessons bearing on Physics should thus be prepared, but many of the others may be successfully used as reading, pure and simple, making them vivid to the children by showing them living illustrations. Many of these can be easily secured for the asking from wholesale grocery houses and manufacturing establishments, while others must be bought or collected by the teacher. Tea, the various stages in the preparation of the coffee berry and of cocoa, palm oil fruit, cocoanuts in their natural state, crude rubber, camphor, resin, turpentine, tar, pitch, cotton balls, crude wool, are some of the things illustrating these lessons which can be secured at small expense. [Revised and adapted for use in schools, with a preface by Mrs. L. L. W. Wilson. For Book IV, see ED623551.]
