PREFACE.

A book may be as noteworthy for what it omits as for what it contains. Arithmetical conundrums," "mathematical monstrosities," " "examples," in which the thing exemplified is lost to the pupil in long rows of figures, and problems suited only to maturity, are omitted from this book. The work presented can be thoughtfully performed by students ten to thirteen years of age if they have been properly prepared for it in the preceding

years.

As in Book I. of this series, classification is made subordinate to gradation. Every set of problems-every problem, has been selected with careful reference to the supposed thought-power of the pupil, and bears close relation to what precedes and to what follows.

The decimal arrangement of the parts of the book whereby a topic is re-presented on every tenth page, insures at once systematic review and the proper relating of the new to the old.
