    Bluegrass Cavalcade

    Kentucky history centers on the Bluegrass; this is not to say that the rest of Kentucky does not have a rich story, but chronologically, the beginning was here. Too, Bluegrass history can scarcely be separated from the rest of the state. Boonesboro and Harrodsburg, Henry Clay and Elizabeth Madox Roberts are the cherished possessions of all Kentuckians. Jane Todd Crawford and Dr. Ephraim McDowell stood in for humanity. It is a great matter of local pride that they did so in Kentucky. Bluegrass Cavalcade brings together fifty-five Kentucky writers to write about their home state and to capture a taste of the rich regional flavor of the Bluegrass as an introduction to Kentucky history. Among the selections included in this volume is represented a small army of distinguished authors who have viewed Kentucky from various perspectives. Edited by revered state historian Thomas D. Clark, Bluegrass Cavalcade is meant to be a literary and historical reception where these esteemed Kentucky writers meet their readers. Featuring Contributions from: John Filson, Basil Duke, Cassius Marcellus Clay, John Fox, Jr., Robert Penn Warren, Harriet , eecher Stowe, Elizabeth Madox Roberts, James Lane Allen, and Henry Watterson Thomas D. Clark, historian laureate of Kentucky, is the author of dozens of books on Kentucky history.https://uknowledge.uky.edu/upk_english_language_and_literature_north_america/1019/thumbnail.jp

    Agrarian Kentucky

    Get PDF
    For subsistence farmers in eastern Kentucky, wealthy horse owners in the central Bluegrass, and tobacco growers in Western Kentucky, land was, and continues to be, one of the commonwealth’s greatest sources of economic growth. It is also a source of nostalgia for a people devoted to tradition, a characteristic that has significantly influenced Kentucky’s culture, sometimes to the detriment of education and development. As timely now as when it was first published, Thomas D. Clark’s classic history of agrarianism prepares readers for a new era that promises to bring rapid change to the land and the people of Kentucky. The historian laureate of Kentucky, Thomas D. Clark, is the author of dozens of books on Kentucky history. Clark in this short, witty, pugnacious book, weaves the rich tapestry of Kentucky’s agrarian history into a picture of the state’s whole development—its religion, its education, its constitutions. A book worth reading. —Virginia Quarterly Review Encapsulates in a highly readable and elegant style the perspective and insights of a remarkable historian. —Nancy O’Malleyhttps://uknowledge.uky.edu/upk_united_states_history/1127/thumbnail.jp

    The Greening of the South: The Recovery of Land and Forest

    Get PDF
    In the early 1920s, in many a sawmill town across the South, the last quitting-time whistle signaled the cutting of the last log of a company\u27s timber holdings and the end of an era in southern lumbering. It marked the end as well of the great primeval forest that covered most of the South when Europeans first invaded it. Much of the first forest, despite the labors of pioneer loggers, remained intact after the Civil War. But after the restrictions of the Southern Homestead Act were removed in 1876, lumbermen and speculators rushed in to acquire millions of acres of virgin woodland for minimal outlays. The frantic harvest of the South\u27s first forest began; it was not to end until thousands of square miles lay denuded and desolate, their fragile soils—like those of the abandoned cotton lands—exposed to rapid destruction by the elements. With the end of the sawmill era and the collapse of the southern farm economy, the emigration routes from the South to the industrial cities of the North and Midwest were thronged with people forced from the land. Yet in the first quarter of this century, even as the destruction of forest and land continued, a day of renewal was dawning. The rise of the conservation movement, the beginnings of the national forests, the development of scientific forestry and establishment of forest schools, the advance of chemical research into the use of wood pulp—all converged even as the 1930s brought to the South the sweeping reclamation programs of the Civilian Conservation Corps and the Tennessee Valley Authority; in their wake came a new generation of wood-using industries concerned not so much with the immediate exploitation of timber as with the maintenance of a renewable resource. In The Greening of the South, this dramatic story is told by one of the participants in the renewal of the forest. Thomas D. Clark, author of many books about southern history, is also an active timber producer on lands in both Kentucky and South Carolina Thomas D. Clark, a distinguished historian, has published widely on Kentucky and southern history. A labor of love by a historian who cherished the land and forests of the South. —Bowling Green Daily News Drawing on more than a half century of intimate acquaintance with the South and its people, Thomas D. Clark has written an informed and readable account of the last century of southern forest history—its destruction, conservation, replanting, and recovery. The result is an important book for everyone interested in the economic history of the South. —Journal of Southern History The story of the fall and rise of Southern forests, an often overlooked element of the region’s history. —Lexington Herald-Leader An important, beautifully written book about a neglected subject in southern history… both entrancing and scholarly. —Register of the Kentucky Historical Society A recounting of an important part of southern economic history and an educational read. —Southsider A forceful statement that should leave no reader doubtful about the regenerative role of woodlands in regional history. . . . A seasoned, regional interpretation of forest history, a much-needed synthesis related in splendidly robust prose. —American Historical Reviewhttps://uknowledge.uky.edu/upk_environmental_policy/1002/thumbnail.jp
