BOOK REVIEWS183 seen as a resolution from above, was the work of blacks themselves rather than the Union armies or President Lincoln and the Republican Congress. Of course Magdol does not make this express argument , but that is the implication of his casual employment of the concept of self-emancipation. Though an appealing idea, it is not supported by evidence. Magdol's book would have been strengthened by a more thoughtful analysis of this matter. Herman Belz University of Maryland Harpers Ferry Armory and the New Technology: The Challenge of Change. By Merritt Roe Smith. (Ithaca: Cornell University Press, 1977. Pp. 363. $17.50.) In recent years historians have devoted increasing attention to technological history and Harpers Ferry Armory and the New Technology is an outstanding addition to the growing list. President George Washington's decision to locate a government arsenal in what was essentially a small isolated rural community on the Potomac River was prompted primarily by regional considerations. Until the Civil War the Armory manufactured arms for the government. Professor Smith discusses the Armory in the context of the local community and region, and compares it with the Springfield (Mass.) Armory, the other major federal arms establishment in the antebellum period. Smith contrasts the "dynamism and devotion to progress" at Springfield to the negative reaction to technological change at Harpers Ferry. The traditional generalization is that "most Americans accepted and welcomed technological change with uncritical enthusiasm." The author clearly demonstrates that this was not true at Harpers Ferry as change was accepted reluctantly. This attitude prevailed in spite of the fact that the Armory had skilled personnel throughout the period and a flow of technical information from Springfield and elsewhere. Smith attributes this to their "lack of contact with the outside world." "In the end," he concludes, "the stamina of local culture is paramount in explaining why the Harpers Ferry Armory never really flourished as a center of technological innovation." Not surprisingly, the author also discovers that local interests considered community needs more important than national goals. Positions of authority at the Armory were tied to a "larger network" of political and economic influence in the community. Management and workers frequently resisted procedures and machines that would have increased efficiency and productivity. Finally, Smith credits John Hall, who established a rifle works adjacent to the Armory, with the first "fully interchangeable weapon 184CIVIL WAR HISTORY in the United States." In a chapter entitled "Hall and the American System," the author argues convincingly that Hall played a major role in the initial stages of the industrial revolution in the United States. The book is well researched and written and fully deserves the Frederick Jackson Turner award for the year's best book-length manuscript in American history which it received in 1977. William N. Still, Jr. East Carolina University To the Webster-Ashburton Treaty: A Study in Anglo-American Relations , 1783-1843. By Howard Jones. (Chapel Hill: The University of North Carolina Press, 1977. Pp. xx, 251. $15.95.) A controversial episode for over a hundred years, the Webster-Ashburton treaty has drawn inordinate scrutiny and criticism from contemporaries and scholars alike. No less than the dean of diplomatic historians, Samuel Flagg Bemis, once accused Daniel Webster of laundering British bribe money destined for Maine journalists (which the author denies) and winning a victory for Britain, while chauvinists in both nations called the agreement a sell out. Complicating a resolution of the Maine boundary dispute was a heritage of transatlantic fear and distrust exacerbated by domestic politics, the Caroline affair, the Creole incident and extradition procedures, the war of Maine "Red Shirts" and New Brunswick "Blue Noses" over the Aroostook, the Washington government's clumsy handling of the McLeod case, not to mention Lord Ashburton's low opinion of the "weak & timid & irresolute" Secretary of State and the American people, a "Mass of ungovernable and unmanageable anarchy" (p. 118). To resolve all the irritants threatening the Anglo-American relationship any treaty necessarily had to be a "package agreement." Drawing on copious research in British and American archives as well as a comprehensive bibliography, Professor Jones has written an absorbing, perhaps definitive, account of a complicated subject.
