WENTWORTH'S ARITHMETICS. 



Crystallized from years of study and experience ; sharp in outline ; 

 clear in substance. These books are characterized, like the author's 

 academic text-books, by the closest adaptation to the needs of the 

 pupil and the requirements of class-room study. They economize 

 time and mental energy, while they secure the most distinct and 

 lasting impressions. Note the following testimonials : 



PBIMABY ARITHMETIC, 

 Warren Holden, Prof. Mathematics, 

 Girard College, Philadelphia : I think 

 it admirably adapted for the purpose 

 intended. 



J. A. Graves, Prin. South Gram- 

 mar School, Hartford, Conn.: I am 

 glad to find at last a real Primary 

 Arithmetic. 



T. M. Balliet, Supt. Schools, Spring- 

 field, Mass. : It is based on right prin- 

 ciples, and the details are worked out 

 with care. 



E. C. Branson, Supt. Schools, Ath- 

 ens, Ga. : The best to date in America ; 

 and, in fact, the only Primary Arith- 

 metic worth putting into the hands of 

 pupils at all. 



J. M. Green, Prin. State Normal and 

 Model Schools, New Jersey : It is a 

 book in which the authors manifest 

 what seems to me to be the true un- 

 derstanding of what constitutes pri- 

 mary work in number. 



S. A. Ellis, Supt. Schools, Rochester, 

 N. Y. : The methods followed are ap- 

 proved by our best educators. The 

 examples are practical and sufficiently 

 numerous ; and, in fact, nothing seems 

 to have been omitted that would tend 

 to give a young pupil a clear and sat- 

 isfactory idea of the various processes 

 in Arithmetic. 



GRAMMAR SCHOOL ARITHMETIC. 



A. B. Fifield, Prin. Eaton School, 

 New Haven, Conn.! It is a model 

 text-book. 



John R. Dunton, Prin. Grammar 

 School, Lewiston, Me. : It is an excel- 

 lent book. Both its matter and meth- 

 ods of treatment are well adapted to 

 grammar school needs. 



E. C. Willard, Prin. High School, 

 Westerly, R.I.: Nearly every page 

 bears the characteristic marks of the 

 author, who easily leads to-day in 

 mathematical book-making. 



P. T. Bugbee, Prin. Union School, 

 Newark, N. Y.: It has stood the test 

 of several years with us, and I consider 

 it superior to any other Arithmetic of 

 grammar grade which I have seen. 



G. S. Albee, Pres. State Normal 

 School, Oshkosh, Wis.: The abun- 

 dance of concrete problems tending 

 to exercise the pupil in more respects 

 than in a mere process, is a very com- 

 mendable feature. 



Edward Taylor, Supt. Schools, Vm- 

 cennes, Ind.: It is sufficient to say 

 that we have been using it as the sole 

 pupil's text in that grade for five years 

 past, and always with entire satisfac- 

 tion.
