[Illustration: DELTA OF THE NILE] The sea upon the coast is shallow, and the fertile country formed by the deposits of the river seems to have projected somewhat beyond the line of the coast; although, as the land has not advanced perceptibly for the last eighteen hundred years, it may be somewhat doubtful whether the whole of the apparent protrusion is not due to the natural conformation of the coast, rather than to any changes made by the action of the river. The Delta of the Nile is so level itself, and so little raised above the level of the Mediterranean, that the land seems almost a continuation of the same surface with the sea, only, instead of blue waters topped with white-crested waves, we have broad tracts of waving grain, and gentle swells of land crowned with hamlets and villages. In approaching the coast, the navigator has no distant view of all this verdure and beauty. It lies so low that it continues beneath the horizon until the ship is close upon the shore. The first landmarks, in fact, which the seaman makes, are the tops of trees growing apparently out of the water, or the summit of an obelisk, or the capital of a pillar, marking the site of some ancient and dilapidated city. The most easterly of the channels by which the waters of the river find their way through the Delta to the sea, is called, as it will be seen marked upon the map, the Pelusiac branch. It forms almost the boundary of the fertile region of the Delta on the eastern side. There was an ancient city named Pelusium near the mouth of it. This was, of course, the first Egyptian city reached by those who arrived by land from the eastward, traveling along the shores of the Mediterranean Sea. On account of its thus marking the eastern frontier of the country, it became a point of great importance, and is often mentioned in the histories of ancient times. The westernmost mouth of the Nile, on the other hand, was called the Canopic mouth. The distance along the coast from the Canopic mouth to Pelusium was about a hundred miles. The outline of the coast was formerly, as it still continues to be, very irregular, and the water shallow. Extended banks of sand protruded into the sea, and the sea itself, as if in retaliation, formed innumerable creeks, and inlets, and lagoons in the land. Along this irregular and uncertain boundary the waters of the Nile and the surges of the Mediterranean kept up an eternal war, with energies so nearly equal, that now, after the lapse of eighteen hundred years since the state of the contest began to be recorded, neither side has been found to have gained any perceptible advantage over the other. The river brings the sands down, and the sea drives them incessantly back, keeping the whole line of the shore in such a condition as to make it extremely dangerous and difficult of access to man.
