The Last of The Mohicans?
What's meaning of the speech of Chingachgook in the ending?
The frontier place is for people like my white son and his woman and their children. And one day there will be no more frontier. And men like you will go too, like the Mohicans. And new people will come, work, struggle. Some will make their life. But once, we were here.
I can't understand it's meaning especially the sentence "But once, we were here."?
