 These two new nottbooh are a new device that make pos- 
 sible tlie keeping of a systematic^ uniform^ concise and complete 
 record oK one's history lessons and of the books one reads. They 
 will be eminently serviceable for recording the data of history les- 
 soris, cr for recalling impressions of books read j and will be pecu- 
 liarly piacticable for teachers — to place iii the hands of students for 
 recording and preserving unpretentious analyses of the studies in his- 
 tory, or of books read in class and in general reading. These two 
 notebooks embody an original device. 1 he many advantages of this 
 leally successful and popular device are ; 
 
 It enables teachers to keep track of home work and 
 
 to secure uniformity throughout the schnol

 SEELEY'S A NEW SCHOOL MANAGEMENT 
 
 This is a readable book. It is sure of a latere 
 sale. Normal schools must make it a text 1 ook. 
 Teachers will prize it as a vade mecum while teaching. 
 Teachers' meetings will take it up for discussion, and 
 we p-edict for it an unusual popularity. It is the 
 latest and best book on a live stibjed and is a credit alike 
 to tlie author and the pubHshers. 
 
 What Page's "Theory and Practice of Teaching" 
 was to young teachers years ago, this new work by 
 Dr. Seeley is to young teachers of the present age. 
 It is in the highest degree a practical, helpful work, 
 especially for teachers in their first gear's work. 
 And for this very reason it is practical and helpful 
 for older teachers also. Educational principles are 
 the same everywhere; they are not graded. The 
 perf. ct school is a structure. Its higher depart- 
 ments are built upon the lower, and the pedagogy 
 applicable to them all rests upon that of the ele- 
 mentary school. Hence a sound body of principles 
 illustrated and explained as clearly and fully as in 
 this new book by Dr. Seeley cannot lose its value to 
 a teacher, even though he may have passed on from 
 the rank of a beginner to that of a veteran.

Page's 
 Theory and Practice of Teaching 
 
 The popularity of Page's book is perennial. It is, 
 so to speak, a staple with educators — as flour is, or 
 sugar is, with a grocer. For more than a generation 
 it has been a standard in normal schools, training 
 schools, and reading circles. Superintendents who 
 themselves studied it twenty years ago when they were 
 just beginning to teach, now prescribe it at regular 
 intervals for the professional study of young teachers 
 whom they are now training! 
 
 More copies of Page's theory and practice 
 have been sold than of any other work on teach- 
 ing. In States which have a State reading 
 circle it is always one of the first works officially 
 adopted, and then gets re-adopted every-so-many 
 years. Its chapters cover : 
 
 The Spirit of the Teacher 
 
 Responsibility of the Teacher 
 
 Habits of the Teacher 
 
 Literary Qualifications of the Teacher 
 
 Right Views of Education 
 
 Right Modes of Teaching 
 
 Conducting Recitations 
 
 Exciting an Interest in Study 
 
 School Government 
 
 School Amusements 
 
 Teachers Relations to Parents of Pupils 
 
 Teacher's Care of His Health 
 
 Teacher's Relation to His Profession 
 
 Miscellaneous Suggestions 
 
 The Rewards of the Teacher 
 
 To impart to the book still greater value for 
 teachers who have to take grade examinations 
 we have added numerous questions and answers 
 
 ON THEORY AND PRACTICE OF TEACHING. 
 
 A teacher is sure to be well-equipped who possess- 
 es Page's book, if in addition he (or she) also possesses 
 Seeley's A new school management, which many 
 teachers tell us is the only rival that, possibly, excels 
 Page's theory and practice.

HOW TO BECOME 
 
 QUICK AT FIGURES- 
 
 OLOTH, 200 PAaES-PEIOE $L00. 
 
 It would seem hardly necessary to enter upon a description 
 Cn detail of this book. Every one knows what it is to be shw 
 at figures ! Who is there to whom quickness at figuring would 
 not come as a godsend ! The title of this book means just that, 
 and there are thousands of testimonials from grateful pur- 
 chasers who thank the publishers for enabling them to become 
 possessed of that which they had not — quickness at figures. 
 
 Short cuts to everything ! Not puzzles ! But easy methods, 
 plain and learnable by every one ! Replete with quick and 
 simple processes for all operations. Are you a teacher of Arith- 
 metic and have you examination papers to correct ? Are you a 
 teacher of anything — not Arithmetic, and have you percent- 
 ages to figure ? Are you a pupil and have you time to be 
 saved ? Are you a clerk ? Are you an employer ? Do you 
 ever buy anything ? Do you ever sell anything ? Do you ever 
 measure anything ? Do you travel ? Do you want tc be 
 more clever than you are ? 
 
 If you wish to please a friend, present a copy of " How to 
 Become Quick at Figures." If you want to please your em- 
 ploy'er, present yourself with a copy. If you want to surprise 
 your teacher, get a copy and use it. If you want to delight 
 your pupils, instruct them in its methods. If your clerks are 
 slow, have them study it. li you are not quick at figures — ! 
 
 If you want to put yourself in a position to demand higher 
 wages, what may you do? If you wish to spend your leisure 
 time profitably, — ^your vacation, say— send for our terms to 
 agents, and go to work, and discover for yourself how readily 
 this book sells.

Best Methods of Teachin 
 in Country Schools 
 
 By G* Dallas hind 
 
 This work is not the fine-spun theory of a college pro- 
 fessor, but the practical ideas of a country teacher, fresh 
 from the country school-room. 
 
 It is not a mass of " glittering generalities," but sug- 
 gestions in detail as to how to teach and manage an un- 
 graded school, drawn from long experience and careful 
 observations. 
 
 1. // /^//j Aow the teacher should conduct himsdf in rela- 
 tion to his patrons and to society in general, 
 
 2. It tells what qualifications are necessary for a good 
 teacher. 
 
 3. // tells how to apply for a school. 
 
 4. It describes in detail the most approved and appli- 
 cable methods of teaching all the branches studied in a 
 country school. 
 
 5. It gives some very practical hints about apparatus and 
 school architecture. 
 
 6. It will give you new insight into your work. 
 
 7. It will lead you to see and realize more pleasure and 
 happiness in your teaching than you have ever been able to get 
 cut of it before. 
 
 8. It will give you the essential principles of practical 
 teaching. 
 
 9. // will tell you Just what to do and how to do it, so that 
 four work will not only be enjoyable^ but profitable. 
 
 No book has ever been published containing so many 
 helpful suggestions of vital interest to Teachers of 
 Country Schools. 
 
 Teachers of Town and City Schools will also derive 
 much benefit from reading the Chapters on the Methods 
 of Teacljing. Reading, Spelling, Arithmetic Geography, 
 General Historv. Physiology. Algebra. Natural Science, 
 Morals and Manners. 
 
 A sample copy will be sent, postpaid, to any teacher for 
 $1.00 (regular price $1.25).

Teacbers, Piipns, Candidates* 
 AT TENTIO N ! 
 
 The most experienced teachers hare, after caitfol 
 preparatior , published three wonderful books. 
 
 In the first one they have put all of the Common 
 branches, over a dozen in all, and then have written each 
 branch in questions and then answered each question in 
 full, making over Seven Thousand Questions with the 
 Seven Thousand Answers, completely exhausting Gram- 
 mar, Geography, Arithmetic, History, Physiology, Spelling, 
 Reading, etc., so that any one, right at home, can become 
 greatly proficient in all these branches without the aid 
 of a teacher. This first book is worth fifty dollars o{ 
 anyone's money in preparing a teacher or student or 
 civil-service candidate, for examination, and the book 
 sells for only $1.50. 
 
 The second book takes up twelve Normal branches 
 in the same way, thus being very desirable for students 
 who are fitting themselves to teach, also for teachers 
 who are studying for examinations for higher grade certifi- 
 cate. 
 
 And the third book takes up the High School 
 branches and exhausts them in a like manner, so any one 
 wishing to prepare for college can use this one. 
 
 For special description of each of these three books 
 separately see the following pages of this leaflet. 
 
 If you return this leaflet 
 
 with your remittance you may deduct jo cents if you 
 order one of the books; deduct yj cents if you order any 
 two of them; deduct $1.25 if you order all three of tl>e 
 ^ooks. 
 
Wby Did He Do It? 
 
 The froblishei* of a well-known "lescchers* monthly h«vio| 
 too,ooo circulation, knowing by experience thai 
 no premium for subscribers is so attractive to teachers 
 as a good question book, selected for that purpose 
 craig's common school question book. He has dis- 
 posed of over twenty thousand copies of it up to now. 
 The manager of said iubnthly is a level-headed publisher and 
 a clever business man; and he knows just how to supply 
 the high quality of merit demanded by teachers in whs^ 
 they read and study, else he could not have built up tho 
 wonderful success which his monthly admittedly is, with 
 its unprecedented list of over 100,000 subscribers! He 
 tells why he selected Craig's Question Book, in a full page 
 announcement in his paper, addressed to the teachers of 
 the United States. The following zvords are wholly 
 kiSt and his alone; not an inkling of them had 
 reached us previous to his printed announcement: 
 
 stands the Test 
 
 TberO'are Question Books and Question Books, good* 
 bad and indififerent, all of more or less value, but there is 
 only one that can really be classed as standard and this 
 one is so pre-eminently superior to all others that it Is 
 Instinctively classed asttie leader. Craig's Question 
 Book has this distinction and justly, so. There is no more 
 critical class of buyers in the world than the American 
 school teachers and when any single book devoted to their 
 Interest is purchased by 192,000 of them (this is the record 
 of Craig's up to Dec. 31, 1902) it must have an abundance 
 of real merit back of it. Such has been the record of 
 the past and its future promises to be even more success* 
 ful than its past has been. 
 
 Thoroughly Revised, 
 
 Enlarged and in every way improved — made Over in fact 
 The publishers of this great book, ever on the alert to 
 keep in the front rank, realized that ' y the expenditure 
 of a few thousand dollars it could be m .de even more use- 
 ful in the great field it occupies. They set about the task, 
 and have so thoroughly performed the work and improved- 
 the book to such a degree that even its old friends woul^ 
 **k recognize it but for the name. 
 
How it was done. 
 
 The entire book was re- written, reset in new type, an elegant 
 mew cover design substituted for the old ; and printed on fine 
 paper substantially bound in doth, it presents an appearance as 
 attractive as the contents are reliable. In the old edition the 
 Questions are tn one chapter by themselves, followed in the next 
 by the Answers, numbered to correspond. Now the Questions 
 and Answers are printed alternately, the former in Italic and 
 the latter in Roman type, thus adding to the value of the book 
 in exactly the same proportion as it is rendered more handy. 
 No expense has been spared, nothing left undone, to bring this 
 work fully up to date in every sense, and the new Craig will 
 meet with even greater favor than the old. 
 
 Our Motive 
 
 In selecting this book from the dozen or more similar ones was, 
 perhaps, a selfish one, because it is so immensely popular (and 
 justly so) among the teachers of this country that it sells more 
 readily than any other. There are others which would yield us 
 a greater profit, but we have declined to handle them simply 
 because they lack the real merit which distinguishes this 
 work. We could not afford to sacrifice our reputation of always 
 giving at tlie smallest cost, the best procurable. 
 
 As a Real Help 
 
 In preparing for examinations, reviews, etc. , a good Question 
 Book can not be over-valued, and the teacher who possesses 
 this book can feel sure that she has the best, and always at 
 hand ready made material for conducting those reviews so neces- 
 sary to success. To the average teacher any one of half a 
 dozen departments in this book is well worth the price.

 ing the following subjects, all carefully rewritten and brought
