sheep and goats driven over it. In a few weeks the entire land, so recently a flooded plain, is overspread with a sea of verdure, which forms a striking contrast to the desert sands and barren hills that rim the valley.
Climate.—In Lower Egypt, near the sea, the rainfall in the winter is abundant; but the climate of Upper Egypt is all but rainless, only a few slight showers falling throughout the year. This dryness of the Egyptian air is what has preserved through so many thousand years, in such wonderful freshness of color and with such sharpness of outline, the numerous paintings and sculptures of the monuments of the Pharaohs.
The southern line of Egypt only just touches the tropics; still the climate, influenced by the wide and hot deserts that hem the valley, is semi-tropical in character. The fruits of the tropics and the cereals of the temperate zone grow luxuriantly. Thus favored in climate as well as in the matter of irrigation, Egypt became in early times the granary of the East. To it less favored countries, when stricken by famine,—a calamity so common in the East in regions dependent upon the rainfall,—looked for food, as did the families of Israel during drought and failure of crops in Palestine.
Dynasties and Chronology.—The kings, or Pharaohs, that reigned in Egypt from the earliest times till the conquest of the country by Alexander the Great (332 B.C.), are grouped into thirty-one dynasties. Thirty of these we find in the lists of Manetho, an Egyptian priest who lived in the third century B.C., and who compiled a chronicle of the kings of the country from the manuscripts kept in the Egyptian temples.
We cannot assign a positive date to the beginning of the First Dynasty, chiefly because Egyptologists are at a loss to know whether to consider all the dynasties of Manetho's list as successive or in part contemporaneous. Thus, it is held by some scholars that several of these families were reigning at the same time in the different cities of Upper and Lower Egypt; while others think that they all reigned at different epochs, and that the sum
