The province of SHENSÍ (_i.e._, Western Defiles) is bounded north by Inner Mongolia, from which it is divided by the Great Wall, east by Shansí and Honan, southeast by Hupeh, south by Sz’chuen, and west by Kansuh. Its area is not far from 70,000 square miles, which is geologically and politically most distinctly marked by the Tsingling shan, the watershed between the Wei and Han rivers. There is only one good road across it to Hanchung fu near its southern part; another, farther east, goes from Sí-ngan, by a natural pass between it and the Fuh-niu shan, to Shang, on the Tan ho, in the Han basin. This part comprises about one-third of Shensí. The other portion includes the basins of the Wei, Loh and Wu-ting, and some smaller tributaries of the Yellow River, of which the Wei is the most important. This river joins the Yellow at the lowest point of its basin, the Tung-kwan pass, where the larger stream breaks through into the lowlands of Honan, and divides eastern and southern China from the northwestern regions. The whole of this part presents a loess formation, and the beds of the streams are cut deep into it, the roads across them being few. The Wei basin is the most fertile part of the province; the history of the Chinese race has been more connected with its fortunes than with any other portion of their possessions. Its productiveness is shown in the rapid development and peopling of the districts along the banks and affluents. On the north, the Great Wall separates Shensí from the Ordos Mongols, its western end reaching the Yellow River at Ninghia--the largest and only important city in that region. All the connections with this region are through Shensí and by Kwei-hwa-ching, but the configuration of the ranges of hills prevents direct travel. None of the rivers in this region are serviceable to any great degree for navigation, and but few of them for irrigation; the crops depend on the rainfall. The climate is more equable and mild than in Shansí, and not so wet as in many parts of Kansuh. The harvests of one good year here furnish food for three poor ones. The chief dependence of the people is on wheat, but rice is grown wherever water can be had; sorghum, millet, pulse, maize, barley, ground-nut, and fruits of many sorts fill up the list. Cotton, hemp, tobacco, rapeseed, and poppy are largely cultivated, but the surplus of any crop is not enough in average years to leave much for export. The ruthless civil war recently quenched in the destruction of the Mohammedans in the province has left it quite desolate in many parts, and its restoration to former prosperity and population must be slow.
