There is one element common to all these religions, and that is the worship of ancestors. Every Chinese, whether he be a Confucianist, a Taoist, or a Buddhist, reverences his ancestors, and prays and makes offerings to their spirits. POLICY OF NON-INTERCOURSE.--The Chinese have always been a very self- satisfied and exclusive people. They have jealously excluded foreigners and outside influence from their country. The Great Wall with which they have hedged in their country on the north, is the symbol of their policy of isolation. Doubtless this characteristic of the Chinese has been fostered by their geographical isolation; for great mountain barriers and wide deserts cut the country off from communication with the rest of the Asiatic continent. And then their reverence for antiquity has rendered them intolerant of innovation and change. Hence, in part, the unwillingness of the Chinese to admit into their country railroads, telegraphs, and other modern improvements. For them to adopt these new- fangled inventions, would be like our adopting a new religion. Such a departure from the ways and customs of the past has in it, to their way of thinking, something akin to disrespect and irreverence for ancestors. CHAPTER II. EGYPT. 1. POLITICAL HISTORY. EGYPT AND THE NILE.--Egypt comprises the delta of the Nile and the flood- plains of its lower course. The whole land is formed of the deposits of the river; hence Herodotus, in happy phrase, called the country "the gift of the Nile." The delta country was known to the ancients as Lower Egypt; while the valley proper, reaching from the head of the delta to the First Cataract, a distance of six hundred miles, was called Upper Egypt. [Footnote: About seven hundred miles from the Mediterranean a low ledge of rocks, stretching across the Nile, forms the first obstruction to navigation in passing up the river. The rapids found at this point are termed the First Cataract. Six other cataracts occur in the next seven hundred miles of the river's course.] Through the same means by which Egypt was originally created, is the land each year still renewed and fertilized. The Nile, swollen by the heavy tropical rains about its sources, begins to rise in its lower parts late in June, and by October, when the inundation has attained its greatest height, the country presents the appearance of an inland sea.
