PREFACE

The one definite purpose of this book is to provide an abundance of thoroughly usable material for the grades below the sixth year in school.

While the valuable features of the Lower Book of the Pupils' Series of Arithmetics are retained, there is interspersed much work that is new; in the present volume, which is, therefore, both a revision and an expansion, the increased material, carefully graded, has been so arranged as to employ judiciously the topical and the spiral plan of teaching arithmetic.
