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 the products mentioned in this volume, such as the grains, fruits, nuts, spices, the various stages in the preparation of cotton, linen, woolen, silk goods and leather may be had for the asking from wholesale grocery houses and manufacturing establishments. [Revised and adapted for use in schools, with a preface by Mrs. L. L. W. Wilson. For Book V, see ED623552.]
