OLNEY'S GEOGRAPHICAL SERIES.

1. OLNEY'S OUTLINE MAPS, AND PRIMARY GEOGRAPHY.— These works are intended for young pupils and form an appropriate in troduction to the larger works.

2. OLNEY'S QUARTO GEOGRAPHY.-The Maps in this work contain but little besides what the pupil is required to learn, consequently it facilitates the progress of the pupil, and saves labor on the part of the teacher. This Geography was prepared at the suggestion of many of the teachers, and is already extensively introduced from preference. Few books have proved so uniformly acceptable for common schools. Its statistical information is very valuable.

3. OLNEY'S SCHOOL GEOGRAPHY AND ATLAS.-This world renowned book is not behind any of its competitors, in point of execution and accuracy. The Atlas is probably superior to any other, and contains a Map of the World as known to the Ancients, besides numerous important tables. The whole work is as complete and correct as a new book, and will continue to maintain its character, though alterations will b avoided as far as possible.

THE BEGINNER'S SERIES.

BENTLEY'S PICTORIAL SPELLING BOOK.-A beautifully illustrated and highly attractive book for children.

GALLAUDET'S ILLUSTRATIVE DEFINER.-The best book for teach ing the right use of words, and the art of composition.

THE STUDENT'S SPEAKER, for young pupils.

THE STUDENT'S SPELLING BOOK, on the Analytical plan, by the author of the "Student's Primer." This new and greatly improved text-book is just published, and destined, when known, to supersede all others, in public favor. Its classification of words and arrangement

of tables are such, that, "by learning to spell and define five thousand words, the pupil will obtain a knowledge of the spelling and significa tion of about fifteen thousand." This feature alone makes it two hundred per cent cheaper, at the same price, than any other Spelling Book
