Beyond this town the united stream takes the name of the Amur (_i.e._, Great River) or Sagalien of the Manchus, running nearly east about 550 miles beyond Albazin, when its course is south-east till it joins the Songari. Most of the affluents are on the north bank; the main channel grows wider as its size increases, having so many islands and banks as seriously to interfere with navigation. The valley thus watered possesses great natural advantages in soil, climate, and productions, which are now gradually attracting Russian settlers. In lat. 47-1/2° the Songari River (_Sung-hwa kiang_ of the Chinese) unites with the Amur on the right bank, 950 miles from Ust-Strelotchnoi, bringing the drainings of the greater portion of Manchuria, and doubling the main volume of water. The headwaters of this stream issue from the northern slopes of the Chang-peh shan; quickly combined in a single channel, these waters flow past the town of Kirin, scarcely a hundred miles from the mountains, in a river twelve feet deep and 900 wide. Near Petuné the River Nonni joins it from Tsitsihar, and their united stream takes the Chinese name of Kwantung (‘Mingled Union’); it is a mile and a half wide here and only three or four feet deep, a sluggish river full of islands. Then going east by north, growing deeper by its affluents, the Hurka, Mayen, Tunni, Hulan, and other smaller ones, it unites with the Amur at Changchu, a hundred miles west from the Usuri. All accounts agree in giving the Songari the superiority. At Sansing, it is a deep and rapid river, but further down islands and banks interfere with the navigation. The Hurka drains the original country of the Manchus.[96] The district south-east of the desert, and north of the Great Wall, is drained and fertilized by the Sira-muren, or Liau River, which is nearly valueless for navigation. Its main and western branch divides near the Ín shan Mountains into the Hwang ho and Lahar; the former rises near the Pecha peak, a noted point in those mountains. The Sira-muren runs through a dry region for nearly 400 miles before it turns south, and in a zigzag channel reaches the Gulf of Liautung, a powerful stream carrying its quota of deposit into the ocean; the width at Yingtsz’ is 650 feet. The depth is 16 feet on the bar at high tide. The Yaluh kiang, nearly three hundred miles long, runs in a very crooked channel along the northern frontiers of Corea. But little is known about the two lakes, Hurun and Pir, except that their waters are fresh and full of fish; the River Urshun unites them, and several smaller streams run into the latter. ~NATURAL RESOURCES OF MANCHURIA.~
