Of the earth dug out of the fish pools he piled up a high mound or barrow, and stocked it well with saplings of oak and beech, ash and pine, and flowering bushes; and about the mound a spiral way wound to the top, and from the top one saw to the four winds over the high woods of Amounderness, and on the west, beyond the forest, the white sands of the shore and the fresh sea.  When the saplings grew tall and stout, the green leaves shut out all sight of the Priory; even the tower of the church; and above the trees in the bright air it was as though one had got half-way to heaven.
