For instance, you know something of the geography of India, without ever having learnt it.

You know that Madras and the Carnatic lie to the east, and Travancore to the southwest, and Malabar to the west, and the Mahratta country and the Nizam's dominions to the north.

Well, that is the geography of this part of the country--that and the names of the towns and rivers.

In the same way, there are a lot of nations in Europe, and you want to know all about them, and where they lie with respect to each other, and the names of their principal towns.

Then there are America, and Africa, and Asia, and all the countries in them.
