Above the Songaree the Amoor was called 'Sakhalin-Oula,' (black water,) by the Manjours and Chinese.

The Goldees named it 'Mongo,' and the Gilyaks called it 'Mamoo.' The name Amoor was given by the Russians, and is considered a corruption of the Gilyak word.

When Mr.Collins descended, in 1857, the natives near Igoon did not or would not understand him when he spoke of the Amoor.

They called the river 'Sakhalin,' a name which the Russians gave to the long island at the mouth of the Amoor.

As the Mongolian maps do not reach the outside world I presume the Russian names are most likely to endure with geographers.
