Two books are of special value to teachers. These are Channing and Hart's _Guide to American History_ [Ginn & Company, Publishers, price $2.00], and Gordy and Twitchell's _Pathfinder in American History_ [Lee & Shepard, Publishers, complete in one volume, $1.20. In separate parts, Part I, 60 cents; Part II, 90 cents]. These two works are replete with suggestions, hints and helps on collateral study, numerous references, detailed lists of topics, and a wide range of other subjects which make them indispensable to the teacher of American history. SCHOOL TEXT-BOOKS FOR READING AND REFERENCE. Pupils should have easy access, by means of the school library or otherwise, to a few of the formal school text-books on American history. In connection with this book Montgomery's _Leading Facts of American History_ and Fiske's _History of the United States_ are especially valuable. The following books are perhaps equally serviceable: Eggleston's _History of the United States_; Steele's _Brief History of the United States_ [usually known as "Barnes's History"]; Thomas's _History of the United States_ and Mowry's _History of the United States_. These books are useful in reading for additional topics, for dates, maps, illustrations, reference tables, and for "filling in" subjects which do not come within the scope of this book. TOPICS FOR COLLATERAL READING. For ordinary school work the text-books to which we have just referred will furnish enough and suitable material for these topics. When, however, standard works on history are of easy access, through the school or public libraries, it is well even for pupils of the lower grades to read sparingly by topics from such works. These topics should be carefully selected by the teacher. They should be brief and call only for a few pages of reading. In the succeeding pages references have been given only to a very few standard works, such as those by Fiske, Parkman, Irving, and McMaster, and such other books as can ordinarily be easily obtained. REFERENCES FOR READING. Pupils should also have easy reference to books from which topics may be read or which may be read sparingly by select passages indicated by the teacher. Many of these books have been suggested more on account of their interesting style than for strict historical accuracy. Read the designated works not as a whole but only by topics or selections. They will do much to awaken and maintain a lively interest in American history. OUTSIDE READINGS.
