A VEGETATION RECONSTRUCTION OF UNION COUNTY, PENNSYLVANIA DURING THE EARLY HISTORICAL PERIOD (1755-1855)

This thesis assesses relationships between vegetation and topography and the impact of human tree-cutting on the vegetation of Union County during the early historical era (1755-1855). I use early warrant maps and forestry maps from the Pennsylvania historical archives and a warrantee map from the Union County courthouse depicting the distribution of witness trees and non-tree surveyed markers (posts and stones) in early European settlement land surveys to reconstruct the vegetation and compare vegetation by broad scale (mountains and valleys) and local scale (topographic classes with mountains and valleys) topography. I calculated marker density based on 2 km x 2 km grid cells to assess tree-cutting impacts. Valleys were mostly forests dominated by white oak (Quercus alba) with abundant hickory (Carya spp.), pine (Pinus spp.), and black oak (Quercus velutina), while pine dominated what were mostly pine-oak forests in the mountains. Within the valleys, pine was strongly associated with hilltops, eastern hemlock (Tsuga canadensis) was abundant on north slopes, hickory was associated with south slopes, and riparian zones had high frequencies of ash (Fraxinus spp.) and hickory. In the mountains, white oak was infrequent on south slopes, chestnut (Castanea dentata) was more abundant on south slopes and ridgetops than north slopes and mountain coves, and white oak and maple (Acer spp.) were common in riparian zones. Marker density analysis suggests that trees were still common over most of the landscape by 1855. The findings suggest there were large differences in vegetation between valleys and mountains due in part to differences in elevation, and vegetation differed more by topographic classes in the valleys than in the mountains. Possible areas of tree-cutting were evenly distributed by topographic classes, suggesting Europeans settlers were clearing land and harvesting timber in most areas of Union County.

SEARCHING FOR HOPE IN SAMUEL BECKETT, EDWARD ALBEE, AND SAM SHEPARD

Reading absurdist plays as hopeful is rare because they are filled with portrayals of horror and despair. However, the tragedy of these plays can allow the audience to experience an atypical kind of hope, often during the final moments of the play. Though the conclusions of the plays are usually ambiguous, this ambiguity and lack of resolutiondoes not preclude hope. The characters persist through their suffering and react in ways that can allow a hopeful affect on the audience. The three absurdist playwrights, Samuel Beckett, Edward Albee, and Sam Shepard, express differing views of the tragic nature of the human condition. However, persistent through all of their work is the ability to view tragedy as having a hopeful affect on the audience. Though the plays do not necessitate a reading of hopefulness, their plays do not preclude this. These absurdist plays do not force the audience into despair, but instead leave open the option of experiencing an expectation and determination for life.
