Four days journey from thence is the great city of Misraim[29], on the banks of the Nile, in which above 2000 Jews are settled. These have two fair synagogues, one of which belongs to the Jews of Palestine and Syria, and the other to those of Babylon; the only difference between which sects is in the way of dividing the law into portions. The Babylonians, every week, read one _Parascha_, after the manner usual in Spain, so as to go through the whole law once in every year; but the others divide each parascha into three _sedarim_, or smaller sections, so that they read over the whole law only once in three years. Yet both of these join in their solemn prayers twice every year. Over the whole Nathaniel presides, being head of the Sanhedrim, and ruler of all the synagogues in Egypt, to which he appoints masters and elders. He is likewise minister of the great king, who resides in the palace of Zoan, a city in Egypt, where Ali, the son of Abitaleb, was once commander of the faithful, and whose subjects are considered as rebels by the other Arabs, because they refuse obedience to the Abassidian khaliff of Bagdat. The royal city is surrounded with walls, but Misraim is entirely open, having the river Nile on one side. This is a very large city, having many large markets and public buildings, and contains many rich Jews. The country is never troubled with rain, ice, or snow, but is often afflicted with insufferable heat. It is watered by the Nile, which begins to swell every year in the month Elul, and continues swelling during that month and Tisri[30], making the earth fruitful. The old Egyptians erected a fine marble pillar of excellent workmanship in an island at this place, rising twelve cubits above the ordinary surface of the river; and when the water overflows that column, the inhabitants are satisfied that their whole country is overspread for fifteen days journey. If the water rise only half the height of the pillar, they then conclude that only half the country is overflowed. A person is stationed by the pillar, who proclaims the height of the water every day at noon. When the water rises to a sufficient height, it indicates a year of fertility and plenty in Egypt; but when it does not overflow, nothing is sown, and sterility and famine are the consequences. The people of the country have trenches dug in their grounds, in which great numbers of fish are caught when the river recedes, which they either use in their families, or salt them for sale. These fish are very fat, and supply oil for lamps. It is an old question, on which there is great diversity of opinion, as to the cause of the overflow of the Nile; but the Egyptians suppose, that it proceeds from the falling of heavy rains in the land of Habash, which we call Havilah or Abyssinia. The fields are usually sowed in the month of September, as the Nile has then retired into its channel. Barley is reaped in February, and wheat in March; and in that
