A ha-ha is an earthen barriers designed to keep the sheep from getting too near the family’s house; the sheep couldn’t jump high enough to get over them. From the house, the ha-ha would be almost invisible, so the sheep were kept at a distance while the view was of an almost unbroken expanse of lawn. The dropped area between was the location of an oxcart road, which, like the ha-ha, was meant to be partially hidden from the view from the house. It connected to the original entrance drive on its northwest end.
