Like-wise the lowland portions of the northern district are cleared and zigzag ridges of the central district, on the other hand, are still forthe most part tree covered. Their bordering slopes are quite too steepand their summit areas are quite too small to tempt the farmer. Theyconstitute ultimate forest land of great value when kept in trees, andof little value, even as sheep or goat pastures, when cleared of their 684 FOREST PHYSIOGRAPHY timber. The drier, sandier ridges formed on resistant sandstone, suchas the Pocono, are marked by stunted growths of scrub pine and redand black oak; the more fertile valleys underlain by limestone have aheavy native growth of walnut, blue ash, etc. The best growth isfound on the highest ridges of eastern West Virginia where the rainfallis notably greater than elsewhere in the PLATE IV
