great abundance in that country during the hot season; but both these theories seem inconsistent with the truth--for rain never falls in Ethiopia, or at least only at rare intervals.
A more common opinion is, that during the continuance of the wind from the north, called the Precursor, and of the Etesian gales, which last forty-five days without interruption, they drive back the stream and check its speed, so that it becomes swollen with its waves thus dammed back; then, when the wind changes, the force of the breeze drives the waters to and fro, and the river growing rapidly greater, its perennial sources driving it forward, it rises as it advances, and covers everything, spreading over the level plains till it resembles the sea.
But King Juba, relying on the text of the Carthaginian books, affirms that the river rises in a mountain situated in Mauritania, which looks on the Atlantic Ocean, and he says, too, that this is proved by the fact that fishes, and herbs, and animals resembling those of the Nile are found in the marshes where the river rises.
But the Nile, passing through the districts of Ethiopia, and many different countries which give it their own names, swells its fertilizing stream till it comes to the cataracts. These are abrupt rocks, from which in its precipitous course it falls with such a crash, that the Ati, who used to live in that district, having lost their hearing from the incessant roar, were compelled to migrate to a more quiet region.
Then proceeding more gently, and receiving no accession of waters in Egypt, it falls into the sea through seven mouths, each of which is as serviceable as, and resembles, a separate river. And besides the several streams which are derived from its channel, and which fall with others like themselves, there are seven navigable with large waves; named by the ancients the Heracleotic, the Sebennitic, the Bolbitic, the Phatnitic, the Mendesian, the Tanitic, and the Pelusian mouths.
This river, rising as I have said, is driven on from the marshes to the cataracts, and forms several islands; some of which are said to be of such extent that the stream is three days in passing them.
Among these are two of especial celebrity, Meroe and Delta. The latter derives its name from its triangular form like the Greek letter; but when the sun begins to pass through the sign of Cancer, the river keeps increasing till it passes into Libra; and then, after flowing at a great height for one hundred days, it falls again, and its waters being diminished it exhibits, in a state fit for riding on, fields which just before could only be passed over in boats.
If the inundation be too abundant it is mischievous, just as it is unproductive if it be too sparing; for if the flood be excessive, it keeps the ground wet too long; and so delays cultivation; while if it be deficient, it threatens the land with barrenness. No landowner wishes it to rise more than sixteen cubits. If the flood be moderate, then the seed sown in favourable ground sometimes returns seventy fold. The Nile, too, is the only river which does not cause a breeze.
Egypt also produces many animals both terrestrial and aquatic, and some which live both on the earth and in the water, and are therefore called amphibious. In the dry districts antelopes and buffaloes are found, and sphinxes, animals of an absurd-looking deformity, and other monsters which it is not worth while to enumerate.
Of the terrestrial animals, the crocodile is abundant in every part of the country. This is a most destructive quadruped, accustomed to both elements, having no tongue, and moving only the upper jaw, with teeth like a comb, which obstinately fasten into everything he can reach. He propagates his species by eggs like those of a goose.
