With difficulty, therefore, could a civilized state originate under such circumstances. So long as life is a scene of uncertainty, the hope of yesterday blighted by the realities of to day, man is the maker of expedients, but not of laws. In his solicitude as to his approaching lot, he has neither time nor desire to raise his eyes to the heavens to watch and record their phenomena; no leisure to look upon himself, and consider what and where he is. In the imperious demand for a present support, he dares not venture on speculative attempts at ameliorating his state; he is doomed to be a helpless, isolated, spell-bound savage, or, if not isolated, the companion of other savages as care-worn as himself. Under such circumstances, however, if once the preliminary conditions and momentum of civilization be imparted to him, the very things which have hitherto tended to depress him produce an opposite effect. Instead of remaining in sameness and apathy, the vicissitudes to which he is now exposed urge him onward; and thus it is that, though the civilization of Europe depended for its commencement on the sameness and stability of an African climate, the conquests of Nature which mark its more advanced stage have been made in the trying life of the temperate zone. [Sidenote: Agriculture in a rainless country.] There is a country in which man is not the sport of the seasons, in which he need have no anxieties for his future well-being--a country in which the sunshines and heats vary very little from year to year. In the Thebaid heavy rain is said to be a prodigy. But, at the time when the Dog-star rises with the sun, the river begins to swell; a tranquil inundation by degrees covering the land, at once watering and enriching it. If the Nilometer which measures the height of the flood indicates eight cubits, the crops will be scanty; but if it reaches fourteen cubits, there will be a plentiful harvest. In the spring of the year it may be known how the fields will be in the autumn. Agriculture is certain in Egypt, and there man first became civilized. The date-tree, moreover, furnishes to Africa a food almost without expense. The climate renders it necessary to use, for the most part, vegetable diet, and but little clothing is required. [Sidenote: Rainless countries of the West.] The American counterpart of Egypt in this physical condition is Peru, the coast of which is also a rainless district. Peru is the Egypt of civilization of the Western continent. There is also a rainless strand on the Pacific coast of Mexico. It is an incident full of meaning in the history of human progress, that, in regions far apart, civilization thus commenced in rainless countries. In Upper Egypt, the cradle of civilization, the influence of atmospheric water is altogether obliterated, for, in an agricultural point of view, the country is rainless. Variable meteorological conditions are there eliminated. [Sidenote: Inundations of the Nile.]
