FROM the heart of a great hill land Glenavelin stretches west and south to the wider Gled valley, where its stream joins with the greater water in its seaward course. Its head is far inland in a place of mountain solitudes, but its mouth is all but on the lip of the sea, and salt breezes fight with the flying winds of the hills. It is a land of green meadows on the brink of heather, of far-stretching fir woods that climb to the edge of the uplands and sink to the fringe of corn. Nowhere is there any march between art and nature, for the place is in the main for sheep, and the single road which threads the glen is little troubled with cart and crop-laden wagon.
