The Chinese have books that purport to give the history of the different dynasties that have ruled in the land from a vast antiquity; but these records are largely mythical and legendary. Everything is confused and uncertain until we reach the eighth or seventh century before our era; and even then we meet with little of interest in the dynastic history of the country until we come to the reign of Che Hwang-te (246-210 B.C.). This energetic ruler strengthened and consolidated the imperial power, and executed great works of internal improvement, such as roads and canals. As a barrier against the incursions of the Huns, he began the erection of the celebrated Chinese Wall, a great rampart extending for about 1500 miles along the northern frontier of the country. [Footnote: The Great Wall is one of the most remarkable works of man. "It is," says Dr. Williams, "the only artificial structure which would arrest attention in a hasty survey of the globe." It has been estimated that there is more than seventy times as much material in the wall as there is in the Great Pyramid of Cheops, and that it represents more labor than 100,000 miles of ordinary railroad. It was begun in 214(?) and finished in 204(?) B.C. It is twenty-five feet wide at base, and from fifteen to thirty feet high. Towers forty feet high rise at irregular intervals. In some places it is a mere earthen rampart; in others it is faced with brick; and then again it is composed of stone throughout.] From the strong reign of Che Hwang-te to the end of the period covered by ancient history, Chinese dynastic records present no matters of universal interest that need here occupy our attention. CHINESE WRITING.--It is nearly certain that the art of writing was known among the Chinese as early as 2000 B.C. The system employed is curiously cumbrous. In the absence of an alphabet, each word of the language is represented upon the written page by means of a symbol, or combination of symbols; this, of course, requires that there be as many symbols, or characters, as there are words in the language. The number sanctioned by good use is about 25,000; but counting obsolete characters, the number amounts to over 50,000. A knowledge of 5000 or 6000 characters, however, enables one to read and write without difficulty. The task of learning even this number might well be hopeless, were it not that many of the characters bear a remote resemblance to the objects for which they stand, and when once explained, readily suggest the thing or idea represented. The nature of the characters shows conclusively that the Chinese system of writing, like that of all others with which we are acquainted, was at first purely hieroglyphical, that is, the characters were originally simply rude outline pictures of material objects. Time and use have worn them to their present form.
