Query: Too Superficial a Study

While American Reformers gives a fair overview of significant individuals and their movements in U.S. history, the book glosses over much material. Walters has accumulated much data, but it comes across as if he's heading a p.r. campaign for reformers instead of digging deep into his area. Much of Walter's writing is very light here and elsewhere (especially in his monthly columns he writes under the name of "Guido Veloce" for the Johns Hopkins Magazine) and at times it appears frivilous.
