A large part of West Virginia is mountainous and hilly. The hills are very fertile to their tops, which are cultivated, and present a remarkable growth of grass. The soil, being clay, does not wash away. The Allegheny range extends along the E. border, and presents the highest levels in the state. Nearly parallel to it on the west, and distant from 20 to 40 m., is a series of ridges and mountains which might properly be termed a continuation of the Cumberland mountains, embracing what are locally known as Flat Top, Cotton Hill, Greenbrier, Gauley, Birch, and Rich mountains, Laurel Hill, & c . The country slopes W. to the valley of the Ohio, and excepting the Potomac, which forms a part of the boundary between this state and Maryland, and its affluents, the rivers of West Virginia are tributary to the Ohio. The chief ones flowing directly into that river are the Big Sandy, Guyandotte, Great Kanawha (called New in the upper part of its course), Little Kanawha, and Monongahela, all of which are navigable. The most important tributaries of the Great Kanawha are the Greenbrier, Gauley, and Elk rivers on the north, and Coal river on the south. The Monongahela is formed in the N. part of the state by the confluence of its West branch and Tygart's Valley river, which have a northerly course. Its chief affluent is the Cheat river, which rises near the sources of the South branch of the Potomac. In the N. E. part of the state the North and South branches of the Potomac flow N. to form that river. All of these streams and their tributa- ries afford water power of unusual abundance ; that at Harper's Ferry, formerly used by the United States government in the manufacture of arms, is the most conspicuous, though many other waterfalls and rapids in the state are not inferior in capacity. There is a system of locks and dams in the Little Kanawha, extending to Burning Spring in Wirt co., one of the oil regions of the state, to which point it is navi- gated by steamboats from Parkersburg. The national government is improving the Great Kanawha by locks and dams, as a part of the national water line from the Atlantic to the west. An appropriation of $400,000 was made for this purpose for the year 1 875, and for the improvement of the Monongahela. The valley of the Great Kanawha is the finest grazing region of the state. Blue grass is indigenous. About two thirds of West Virginia is covered with forests. Large quantities of ginseng have been shipped from the state. The lumber trade is important. The chief kinds produced are oak, poplar, and hemlock, which abound throughout the state except on a few high lev- els. Next in importance, though not so abun- dant, are walnut, cherry, buttonwood, ash, chestnut, and locust. In the basins of the Kanawhas, Guyandotte, Monongahela and its tributaries, and Big Sandy, oaks, hickories, and poplars reach a height of from 75 to 100 ft. One of the most extensive pine regions in the state extends through Fayette and Raleigh counties along the New river. The Allegheny coal field, which stretches from the N. part of Pennsylvania to the middle of Alabama, com- prises within its limits the greater part of West Virginia. (See COAL.) The area of the coal formation in the state has been estimated at more than 15,000 sq. m., but much of this is unavailable for want of means of transporta- tion, and mines have been opened in only a small part of it. The coal is found in two productive layers or groups, the upper and
