The province of SHANSÍ (_i.e._, West of the Hills) lies between Chihlí and Shensí, and north of Honan; the Yellow River bounds it on the west and partly on the south, and the Great Wall forms most of the northern frontier. It measures 55,268 square miles, nearly the same as England and Wales, or the State of Illinois. This province is the original seat of the Chinese people; and many of the places mentioned and the scenes recorded in their ancient annals occurred within its borders. Its rugged surface presents a striking contrast to the level tracts in Chihlí and Shantung. The southern portion of Shansí, including the region down to the Yellow River, in all an area of 30,000 square miles, presents a geological formation of great simplicity from Hwai king as far north as Ping ting. The plain around the first-named city is bounded on the north by a steep, castellated range of hills which varies from 1,000 to 1,500 feet in height; it has few roads or streams crossing it. On reaching the top, an undulating table-land stretches northward, varying from 2,500 to 3,000 feet above the Plain, consisting of coal formation, above the limestone of the lower steep hills. About forty miles from those hills, there is a second rise like the first, up which the road takes one to another plateau, nearly 6,000 feet above the sea. This plateau is built up of later rocks, sandstones, shales, and conglomerates of green, red, yellow, lilac, and brown colors, and is deeply eroded by branches of the Tsin River, which finally flow into the Yellow River. This plateau has its north-west border in the Wu ling pass, beyond which begins the descent to the basin of the Făn River. That basin is traversed near its eastern side by the Hoh shan nearly to Taiyuen; its peaks rise to 8,000 feet in some places; the rocks are granite and divide the coal measures, anthracite lying on its eastern side and bituminous on the west, as far as the Yellow River, and north as far as Ta-tung. On top of both plateaus is spread the loess deposit, varying in depth from ten to five hundred feet, and deeply gullied by water-courses in every direction, which expose coal and iron mines.
