Nonni

— In the western range, and about sixiy miles from the Argun River, rises the Nonni, the most important waterway flowing through the province. On its way to the Sungari, which it joins at Shui-shih-ying-tzu, twenty miles to the north of the town of Petuna (Hsin Ch'eng), it passes on its left bank the town of Mergen and Tsi-tsi-har, known to the Chinese as Pu-k'uei, the capital of the province.
