In the use of this book there are no lessons to “commit and recite.” The pupil commences with actual specimens of plants which every one is able to collect, and learns to look with his own eyes and think with his own mind. Children can begin to study plants successfully by this method as soon as they can write, and any teacher, without previous knowledge of the subject, can conduct them through the exercises without difficulty.

Miss Youmans claims that Botany may be made to do for the observing faculties what mathematics does for the reasoning faculty, and, in preparing a book by which this work may be commenced, she has met the profoundest need of popular educa. tion.

The volume is as practical as possible. To aid the student in identifying the stars and constellations, the fine Celestial Charts of Arago, which answer all the purposes of a costly Atlas of the Heavens, are appended to the work-this being the only text-book, as far as the Publishers are aware, that possesses this great advantage. Directions are given for finding the most in. teresting objects in the heavens at certain hours on different evenings throughout the year. Every device is used to make the study interesting; and the Publishers feel assured that teachers who once try this book will be unwilling to exchange it for any other.
