SHELDON, formerly Professor of History in Wellesley College. This book has been prepared in order that the general student may share in the advantages of the Seminary Method of Instruction. It is a collection of historic material, interspersed with problems whose answers the student must work out for himself from original historical data. In this way he is trained to deal with the original historical data of his own time. In short, it may be termed _an exercise book in history and politics_. Price by mail, $1.75. +THE TEACHER’S MANUAL+ contains the continuous statement of the results which should be gained from the History, and embodies the teacher’s part of the work, being made up of summaries, explanations, and suggestions for essays and examinations. Price by mail, 85 cents. _Sheldon’s Studies in Greek and Roman History._ Meets the needs of students preparing for college, of schools in which Ancient History takes the place of General History, and of students who have used an ordinary manual, and wish to make a spirited and helpful review. Price by mail, $1.10. _Methods of Teaching and Studying History._
