Gr 8 Up Hanmer examines the westward expansion of the United States' frontiers in reference to Frederick Jackson Turner's thesis, which attributes the development of the American character and adherence of Americans to democratic institutions to the advancing western frontier. However, Hanmer points out that Turner's thesis was not always true. One excellent chapter on prejudice and oppression makes it clear that Native Americans, blacks, Mormons, and others did not benefit from the westward movement of democratic institutions. The inclusion of a generous number of quotations from Horace Greeley, Luther Standing Bear, Walt Whitman, Edgar Guest, and others adds to the readability of this otherwise factual, dry account. This material can be found elsewhere, but it must be extracted a chapter at a time from a variety of books. Junior high school students will find the information complete enough for research purposes, but will probably not want to read it from cover to cover. Some black-and-white reproductions of contemporary paintings, prints, and photos are included, but they add no excitement to the text. No time line or maps are included. Janet E.
