why can't we find hosahalli village on map?

Ranga conjectures or guesses that there is no mention of the place in any geography book because these books are written by the sahibs in English writing in their language who are probably unaware of the existence of such a place. Hence, it does not find any mention. Not even the natives know about such a place because it is a remote place in one corner of the country and too small to be taken note of and remembered.
