Now when Wildlake’s Way was gotten to Carlstead, there was an end of it toward the north; though beyond it in a right line the wood was thinner, because of the hewing of the Carles. But the road itself turned west at once and went on through the wood, till some four miles further it first thinned and then ceased altogether, the ground going down-hill all the way: for this was the lower flank of the first great upheaval toward the high mountains. But presently, after the wood was ended, the land broke into swelling downs and winding dales of no great height or depth, with a few scattered trees about the hillsides, mostly thorns or scrubby oaks, gnarled and bent and kept down by the western wind: here and there also were yew-trees, and whiles the hillsides would be grown over with box-wood, but none very great; and often juniper grew abundantly. This then was the country of the Shepherds, who were friends both of the Dalesmen and the Woodlanders. They dwelt not in any fenced town or thorp, but their homesteads were scattered about as was handy for water and shelter. Nevertheless they had their own stronghold; for amidmost of their country, on the highest of a certain down above a bottom where a willowy stream winded, was a great earthwork: the walls thereof were high and clean and overlapping at the entering in, and amidst of it was a deep well of water, so that it was a very defensible place: and thereto would they drive their flocks and herds when war was in the land, for nought but a very great host might win it; and this stronghold they called Greenbury.
