The travel between Shensí and Sz’chuen is almost wholly confined to the great road reaching from Sí-ngan to Chingtu. It passes along the River Wei to Hienyang hien on the left bank, where the road north into Kansuh diverges, the other continuing west along the river through a populous region to Paokí hien, where it recrosses the Wei. During this portion, the Tai-peh Mountain, about eleven thousand feet high, with its white summit, adds a prominent feature to the scenery. At Paokí, the crossing at the Tsingling shan commences, and occupies seven days of difficult travel through a devious road of 163 miles to Fung hien on the confines of Kansuh. It crosses successive ridges from 6,000 to 9,000 feet high, and is carried along the sides of hills and down the gorges in a manner reflecting much credit on the engineers of the third century A.D. who made it. These mountainous regions are thinly settled all the way down to Paoching, near Hanchung; but upon gaining the River Han, one of the most beautiful and fertile valleys in China is reached. Its western watershed is the Kiu-tiao shan,[73] running southwesterly into Sz’chuen on the west side of the Kialing River. ~SÍ-NGAN ITS CAPITAL.~ The city of Sí-ngan is the capital of the northwest of China, and next to Peking in size, population, and importance. It surpasses that city in historical interest and records, and in the long centuries of its existence has upheld its earlier name of _Chang-an_, or ‘Continuous Peace.’ The approach to it from the east lies across a bluff, whose eastern face is filled with houses cut in the dry earth, and from whose summit the lofty towers and imposing walls are seen across the plain three miles away. These defences were too solid for the Mohammedan rebels, and protected the citizens while even their suburbs were burned. The population occupies the entire enciente, and presents a heterogeneous sprinkling of Tibetans, Mongols and Tartars, of whom many thousand Moslems are still spared because they were loyal. Sí-ngan has been taken and retaken, rebuilt and destroyed, since its establishment in the twelfth century B.C. by the Martial King, but its position has always assured for it the control of trade between the central and western provinces and Central Asia. The city itself is picturesquely situated, and contains some few remains of its ancient importance, while the neighborhood promises better returns to the sagacious antiquarian and explorer than any portion of China. The principal record of the Nestorian mission work in China, the famous tablet of A.D. 781, still remains in the yard of a temple. Some miles to the northwest lies the temple Ta-fu-sz’, containing a notable colossus of Buddha, the largest in China, said to have been cut by one of the Emperors of the Tang in the ninth century. This statue is in a cave hewn out of the sandstone rock, being cut out of the same material and left in the construction of the grotto. Its height is 56 feet;
