Definition of "Amoor"

Of the Mongall Tartars.The Mongalls are a numerous people, and occupy a large extent of country, from this place to the Kallgan, which ſignifies the everlaſting Wall, or the great wall of China. From this wall they ſtretch themſelves northward as far as the river Amoor; and from the Amoor, weſtward, to the Baykail ſea ; where they border with the territories of the Kontayſha, or prince of the black Kalmucks. On the fouth, they are bounded by a nation called Tonguts, among whom the Delay Lama has his residence.

Some time ago, the Russian Government ordered two large steamtugs, destined for the navigation of the river Amoor, at the establishment of Messrs, Cockerill and Co. of Seraing, near Liége; The Indépendance Belge now states that the engines of the vessels have just been finished, and are on the point of being sent overland to their destination together with a number of skilful engineers, engaged by the Russian Government. The Belgian paper, on giving these news gets quite enthusiastic about the newly gained possessions of the Czar in Asia, "The course of the River Amoor is not less than six-hundred and seventy-five geographical miles long," exclaims the Indépendance, “and while its waters are bathing China on the one side, they touch Siberia on the other.”

This Nerchinsk Treaty, exacted literally at the cannon's mouth, was not only the first concluded between China and Russia, but the first between China and any foreign Power. It was essentially a boundary treaty, though free trade between the two countries was also provided for ; yet the Chinese made the fatal mistake of leaving the eastern frontier, beyond the line of the Ussuri, for future definition, their only excuse being ignorance of the country ; though the Ming Emperors Hun-wu (1368-98) and Yun-lo, in 1413, had sent expeditions to the lower Amoor ; built temples there ; and erected stone monuments, with inscriptions, that still exist.
