Its coast is studded with low islands and sandbanks, the results of the deposits brought down by the Hwang-ho.
The Hwang-ho river in China is peculiarly liable to these inundations.
Formerly it received through the Sha-ho part of the waters of the Hwang-ho.
Western Kan-suh is mountainous, and largely a wilderness of sand and snow, but east of the Hwang-ho the country is cultivated.
From the neighbourhood of Peking to the Hwang-ho there is an inner and an outer wall.
