The object of this little book is threefold: first, to show the pupil some practical uses of the graphic method; second, to plan a course in graphic algebra that will lead naturally and along interesting paths to the work in the solution of equations; and finally to save both teacher and pupil time and energy needed to hunt up suitable material. Every type of work outlined in the book has been tested and found suitable for classroom use. The writer has done a considerable amount of work in this line with her classes for the past nine years, and has never failed to find it a spring by means of which she has been enabled to arouse an interest in the mathematics. Though elementary in its form, it is believed the monograph will be found to be thoroughly scientific. It endeavors to introduce in simple form ideas which the pupil will come to deal with in more advanced work and in no case introduces an idea which must sooner or later be unlearned. In the Appendix at the end of the book may be found a number of statistical tables, obtained chiefly from theB ureau of Statistics at Washington, from which teacher and pupil may freely draw without waste of time. The writer has aimed to cover a wide variety of topics and at the same time to select those in which figures were not too large for convenient use. MATILDA AUERBACH, Ethical Culture High School.
