Certainly it looks strong enough to last as long as the Nile itself. Strength, and nothing but strength, shows in every stone of it. Square, solid, and massive, it runs from shore to shore in an absolutely straight line, without the slightest attempt at any trace of ornament or decoration. Clearly, effect has been the last thing thought of. Even the sluice-gates have absolutely plain rectangular openings, and it detracts from the symmetry of the design that, owing to engineering exigencies, they are not all of one height, but run in sections of five, some of them lower than others. The top of the wall runs in a simple, unbroken level; there is nothing to catch the eye as it travels up the steep face of masonry except the slightest change in the angle of the slope to a nearly complete perpendicular. The wall simply leaves off because its builders thought it high enough for the present. Along the broad surface of the summit runs a tramway, with plenty of room for a man to walk on either side, flanked by perfectly plain, solid parapets as high as the waist, and more than a yard thick, of a piece with the masonry below. On the eastern side the Dam is unostentatiously built into the living rocks; no arch or pylon marks its start. On the western side it is flanked by a ladder of four immense locks, set in a mountainous embankment. The gallows-like arms of the draw-bridge, hideous in appearance, but a marvel of mechanical ingenuity, over the upper gate of the highest lock are the only break in the long, unrelieved level. The hard gray colour of the granite strengthens the general impression, though in time every part exposed to the action of the water will be coated with the shining black varnish which the Nile mud always lays on granite, and it will look exactly the same as the natural bed of the stream. How different all this is from the prettiness of the Delta Barrage, with its brickwork, originally designed and built under French influence, adorned with archways and towers, of which the lovely garden, with its flowers and shrubs, its green lawns and leafy trees, on the tongue of land which it crosses, seems a natural and appropriate part! The Assouan Dam is the work of a practical, unimaginative race. Its builders have had before them the problem of harnessing the great river with a yoke that cannot be broken; they had to hold up a reservoir containing 100,000,000 tons of water, so that for 140 miles the river is turned back upon itself; and they have succeeded.
