  • APPALACHIAN AND WHITE MOUNTAIN WATERSHEDS. 21 of that which is underground is carried on in the ancient crystalline rocks, which do not require timbering. The influence of such mining upon the forests is not very important except in a few instances where great damage is done. The most pronounced example of injury by mining is at Ducktown, Tenn., where sulphur fumes from the roasting and smelting of copper ores have killed all vegetation for a number of miles around. The perfectly bare surface has eroded with wonderful rapidity. It is a striking illustration of the completeness of destruction that may result from erosion in this region when the protecting forest cover is once removed. In the Alleghenies and Cumberlands the mining of coai overshadows all other mining operations. This is one of the richest coal fields of the United States. The great mines which have been developed require annually millions of feet of timber, and will continue to require great quantities so long as the coal supply lasts. Coal mining does not necessarily conflict with the proper use of the forest. It requires the use of usually less than 10 per cent of the surface, and this generally in the valleys. All the rest can be kept in timber. Moreover, the ownership and control of the surface do not necessarily go with the control of the coal rights. In many cases the companies which work the mines control only enough of the surface to enable them to operate the collieries. AGRICULTURAL POSSIBILITIES. In the northern part of Virginia the Blue Ridge is composed of sandstone which gives rise to the DeKalb stony loam, for the most part a poor, thin, stony soil. The summits are rough, rocky, and sharp-crested, while the slopes are steep and rocky. Probably 95 per cent of this type is uncultivated, and is valuable only for the timber it supports. The Blue Ridge, with its outlier, Short Mountain, is well denned, and soils suited to agriculture come to its base. Immediately across the Potomac, in western Maryland, similar conditions prevail. Farther south, in Virginia, the Blue Ridge soils are much more productive, and it is only the steep upper portions that are unsuited to farming. These higher areas are so steep, rough, and rugged that they are adapted only to forestry. In western North Carolina, east of the Blue Ridge, lies a succession of foothills with moderately precipitous slopes and with small valleys between. To the eastward lies the great agricultural Piedmont Plateau, from which little valleys follow back through the foothill region and into the mountains. At first these valleys are adapted to general farming, but as the region becomes more rugged they are pinched out and the soil is unsuited to cultivation. ONLY SMALL AREA ADAPTED TO ORCHARD GROWING. Where the Blue Ridge supersedes the foothills, many orchards have been planted on the better soils, and it is these in part which have given to western North Carolina the reputation of producing good fruit—a reputation justly deserved and capable of being much extended.
