Further on the cultivable land reappears, but narrowed, and changed almost beyond recognition. Hills, hewn out of solid sandstone, succeed each other at distances of about two miles, low, crushed, sombre, and formless. Presently a forest of palm trees, the last on that side, announces Aswan and Nubia. Five banks of granite, ranged in lines between latitude 24 deg. and 18 deg. N., cross Nubia from east to west, and from north-east to south-west, like so many ramparts thrown up between the Mediterranean and the heart of Africa. The Nile has attacked them from behind, and made its way over them one after another in rapids which have been glorified by the name of cataracts.

Classic writers were pleased to describe the river as hurled into the gulfs of Syne with so great a roar that the people of the neighbourhood were deafened by it. Even a colony of Persians, sent thither by Cambyses, could not bear the noise of the falls, and went forth to seek a quieter situation. The first cataract is a kind of sloping and sinuous passage six and a quarter miles in length, descending from the island of Philae to the port of Aswan, the aspect of its approach relieved and brightened by the ever green groves of Elephantine. Beyond Elephantine are cliffs and sandy beaches, chains of blackened "roches moutonnees" marking out the beds of the currents, and fantastic reefs, sometimes bare and sometimes veiled by long grasses and climbing plants, in which thousands of birds have made their nests. There are islets too, occasionally large enough to have once supported something of a population, such as Amerade, Salug, Sehel. The granite threshold of Nubia, is broken beyond Sehel, but its debris, massed m disorder against the right bank, still seem to dispute the passage of the waters, dashing turbulently and roaring as they flow along through tortuous channels, where every streamlet is broken up into small cascades, ihe channel running by the left bank is always navigable. [Illustration: 015.jpg ENTRANCE TO NUBIA.] During the inundation, the rocks and sandbanks of the right side are completely under water, and their presence is only betrayed by eddies. But on the river's reaching its lowest point a fall of some six feet is established, and there big boats, hugging the shore, are hauled up by means of ropes, or easily drift down with the current.
