Fern’s Hollow by Hesba Stretton

Just upon the border of Wales, but within one of the English counties, there is a cluster of hills, rising one above the other in gradual slopes, until the summits form a long, broad tableland, many miles across. This tableland is not so flat that all of it can be seen at once, but here and there are little dells, shaped like deep basins, which the country folk call hollows; and every now and then there is a rock or hillock covered with yellow gorse bushes, from the top of which can be seen the wide, outspread plains, where hundreds of sheep and ponies are feeding, which belong to the farmers and cottagers dwelling in the valley below. Besides the chief valley, which divides the mountains into two groups, and which is broad enough for a village to be built in, there are long, narrow glens, stretching up into the very heart of the tableland, and draining away the waters which gather there by the melting of snow in the winter and the rain of thunderstorms in summer.
