“ The district is traversed by excellent roads in all directions. The northern summits are destitute of trees, but the lower slopes of the Upper Harz are heavily wooded with pines and firs. Between the forests of these stretch numerous peat-mosses, which contain in their spongy reservoirs the sources of many small streams. On the Brocken are found one or two arctic and several alpine, plants. In the Lower Harz the forests contain a great variety of timber. The oak, elm and birch are common, while the beech especially attains an unusual size and beauty. ”
