The city presents a brilliant kaleidoscope of nationalities: Mohammedans with red turbans, Tartars wearing red panels; Mongols with blue turbans; high-booted, bewhiskered Russians; booted Tibetans; blue-gowned Chinese; yellow-robed Lamas; now and then a top-knotted aborigine; robed Manchus; and descendants of the original Tsin and Chou tribes of Chinese who came east to China from the cradle of the race, seated in the saddle of pioneer conquerors; and with the Hebrews, these Singan men can probably boast that they bring down the purest blood from the dispersion of Ararat. Descendants of kings and generals of many a dynasty now plough farms on the plain, and they will tell you: “Yes, I am the son of a king.” Near here the builder of the Great Wall, infinitely the greatest mason and military commander of history, the Emperor Tsin, 220 B. C., had his capital at Hsien Yang. His huge pyramidal mound, and other burial mounds, are among the world’s greatest curiosities. On the plain are the two unique marble arches, with four roofs, erected by Governor Lu to the memory of his mother and wife, in the China where some writers say women meet with no honor. A stone bridge of seventy arches over the Pa River, and the hot sulphur springs of Lin Tung, are notable. The round, instead of square stone piers, are unique in China, and show Moslem influence. Not all Chinese cities were without attention from the sanitary engineer. Old culverts and drains constructed by the ancient kings of the north exist in Singan and elsewhere, and some of the southern cities have drainage canals, sewage canals not being considered necessary, as the night-soil is collected for fertilization. China, however, is going to drain her cities so as to carry off expectoration and decaying matter. The smells which the tourist revolts at are not as dangerous as they seem, as opium, peculiar incense, and vegetable cooking oils, such as sesamum, peanut, bean, etc., contribute the most malodorous portion.
