jammed between the rocks, or embedded in sandbanks, emerge into view, as if to warn sailors and discourage them from an undertaking so fraught with perils. Usirtasen I. realized the importance of the position, and fortified its approaches. [Illustration: 346.jpg THE SECOND CATARACT AT LOW NILE] He selected the little Nubian town of Bohani, which lay exactly opposite to the present village of Wady Haifa, and transformed it into a strong frontier fortress. Besides the usual citadel, he built there a temple dedicated to the Theban god Amon and to the local Horus; he then set up a stele commemorating his victories over the peoples beyond the cataract. [Illustration: 349.jpg THE TRIUMPHAL STELE OF USIRTASEN I.] Drawn by Faucher-Gudin, from a photograph of the original in the museum at Florence. Ten of their principal chiefs had passed before Amon as prisoners, their arms tied behind their backs, and had been sacrificed at the foot of the altar by the sovereign himself: he represented them on the stele by enclosing their names in battlemented cartouches, each surmounted by the bust of a man bound by a long cord which is held by the conqueror. Nearly a century later Ûsirtasen III. enlarged the fortress, and finding doubtless that it was not sufficiently strong to protect the passage of the cataract, he stationed outposts at various points, at Matûga, Fakus, and Kassa. They served as mooring-places where the vessels which went up and down stream with merchandise might be made fast to the bank at sunset. The bands of Bedouin, lurking in the neighbourhood, would have rejoiced to surprise them, and by their depredations to stop the commerce between the Said and the Upper Nile, during the few weeks in which it could be carried on with a minimum of danger. A narrow gorge crossed by a bed of granite, through which the Nile passes at Semneh, afforded another most favourable site for the completion of this system of defence. On cliffs rising sheer above the current, the king constructed two fortresses, one on each bank of the river, which completely commanded the approaches by land and water. On the right bank at Kummeh, where the position was naturally a strong one, the engineers described an irregular square, measuring about two hundred feet each side; two projecting bastions flanked the entrance, the one to the north covering the approaching pathways, the southern one commanding the river-bank. A road with a ditch runs at about thirteen feet from the walls round the building, closely following its contour, except at the north-west and south-east angles, where there are two projections which formed bastions. The town on the other bank, Samninû-Kharp-Khâkerî, occupied a less favourable position: its eastern flank was protected by a zone of rocks and by the river, but the three other sides were of easy approach. They were provided with ramparts which rose to the height of eighty-two feet above the plain, and were strengthened at unequal
