That part of the old estate of Middlebie which remained to the heirs of Maxwell was situate on the right or westward bank of the Water of Orr, or Urr, in Kirkcudbrightshire, about seven miles from Castle-Douglas, the market-town, ten from Dalbeattie, with its granite quarries, and sixteen from Dumfries. It consisted chiefly of the farm of Nether Corsock, and the moorland of Little Mochrum. But, before building, Mr. Clerk Maxwell by exchange and purchases had added other lands to these, including the farm of Upper Glenlair. The site chosen for the house was near to the march of the original estate, where a little moor-burn from the westward falls into the Urr. The two streams contain an angle pointing south-east, opposite the heathery brae which hides the village of Kirkpatrick Durham. There, on a rising ground above the last descent towards the river and the burn, a mansion-house of solid masonry, but of modest dimensions, had been erected. It was built of dark-gray stone, with a pavement and a “louping-on-stane” of granite before the front door. On the southward slope, towards the burn, was a spacious garden-ground and a plantation beyond it, occupying the den or dingle on either side the burn, and coming round to westward of the house and garden, where it ended in a shrubbery, by which the house was approached from the north. On the eastward slope, towards the Water of Urr, was a large undivided meadow for the “kye” and the ponies.
