“On the 9th December 1811 Mr. Rich made an expedition to the Birs-i-Nimrúd. He found vestiges of mounds all round it to a considerable extent, and the country traversed by canals in every direction. The soil round it is sandy. Close to the Birs, or at about a hundred yards from it, and parallel with its southern front, is a high mound, almost equal in size to that of the Kasr. “‘The Birs,’ says he, ‘is an enormous mound. At the north end it rises, and there is an immense brick wall, thirty-seven feet high and twenty-eight in breadth, upon it. This wall is not in the centre of the north summit of the mound, but appears to have formed the southern face of it. The other parts of the summit are covered by huge fragments of brickwork, tumbled confusedly together; and what is most extraordinary is that they are partly converted into a solid vitrified mass. The layers are in many parts perfectly distinguishable; but the whole of these lumps seem to have undergone the action of fire. Several lumps of the same matter have rolled down, and remain partly on the side of the mound and partly in the plain. The large wall on the southern face of the summit is built of burnt bricks, with writing on them, and so close together that no cement is discoverable between the layers. Small square apertures are left, which go quite through the building, and are arranged in a kind of quincunx form. Down the face of the wall the bricks have been separated, leaving a large crack. On the side towards the mound of Ibrahím Khalil, the mound slopes gradually down, and up nearly half its height is a flat road running round this part of it, twenty of my paces broad.
