It annuls former treaties, and establishes a postal arrangement between Pekin and Kiachta.
I presume the oversight in the treaty was on the part of the Chinese, as the Russians are too shrewd in diplomacy to omit any point of advantage.

Nothing is said about the land in the Amoor.

"The land on the north bank is Russian, and on the south bank Chinese." What is to be the nationality of the islands in the river?
Some of them are large enough to hold a population of importance, or be used, as the sites of fortifications.

There are duchies and principalities in Europe of less territorial extent than some islands of the Amoor.
When Russia desires them she will doubtless extend her protection, and I observed during my voyage that several islands were occupied by Russian settlers for hay-cutting and other purposes.

Why could not an enterprising man of destiny like the grey-eyed Walker or unhappy Maximilian penetrate the Amoor and found a new government on an island that nobody owns?
Quite likely his adventure would result like the conquests of Mexico and Nicaragua, but this probability should not cause a man of noble blood to hesitate.
Below the Ousuree the Russian villages were generally on the south bank of the river, but after passing that stream I found them all on the north side.
