DUNBAR'S A Presentation of Business Methods Based upon Inductively Developed Principles. By J. H. Dunbar, A. M., Claremont, N. H. Published in Four Parts, Parts I and II now ready, Parts III and IV in preparation. The following are the two points of special superiority claimed for this work: It develops arithmetical principles, in place of presenting arbitrary arithmetical rules; it thus stimulates the interest and expands the mind of the pupil. It aims to present direct, common-sense, business-like methods, and thus to produce correct and rapid accountants. That these claims are not without some foundation will, we think, be admitted by those who read the testimonials in this circular from prominent business men and well-known educators and school officials. An idea of the plan followed in the development of principles may be obtained from the sample page on the back of this circular. Such development of a principle is always followed by model solutions, complete and systematic explanations, and a large number of exercises for practice. THE HOWE PRESS, GRANTHAM, N. H. Comes to the Hartford, Vt., Aug. 8, 1894. Prof. J. H. Dunbar, Dear Sir: I have carefully examined your “InPlain of (ompre ductive Arithmetic,” and find it more than interesting. hension It presents a method of instruction for the school room which is at once original, clear, and plain of comprehension to the student mind. Its arrangement is methodical, building on from one branch to another in logical sequence, so as to present a truly inductive A truly inductive system of instruction. system Its propositions and definitions are terse and come directly to the point. From the business man's standpoint it also has superior suggestions and practical methods. Its ready ways of calculation in every-day transactions, and particularly in matters of interest computations, are quick and economize one's time. A complete directly mastery of this work by the student would seem to equip him for point all the arithmetical problems of commercial and ordinary business life. Your treatise deserves success and will command it. Truly yours, (Ex-Governor of Vermont, and President Samuel E. Pingree. of White River Saving Bank ) lepart Bethel, Vt., June 28, 1894. J. H. Dunbar, Esq., Dear Sir: I have recently examined a copy of your Arithmetic with much interest. It is a new departure in the Educates line of text-books. The arrangement is admirable, and the style instructs clear, simple, and logical. It seems calculated to stimulate the mind of the pupil and suggest practical methods to the instructor; to educate as well as to instruct. The treatment of the subject of interest is the best I have ever seen, accurate and plain.

Dear Sir: Effects qnick, results, and the way in which from first to last the pupil is led to correct solutions reason logically. Because its methods thus effect quick, correct solutions, and at the same time tend to develop the reason, it meets equally the demand both of the business man and the teacher. The pupil must receive from its study that intellectual stimulus Meets cle mund which he fails to get from those arithmetics which merely frame both of business rules for purely mechanical processes. mart and Yours cordially, teacher Prin.

We never have had any book so good for supplementary work or one which awakened the reasoning faculties in children so well. I should recommend its use in any school advanced enough to use it.
