I never dream beyond our high, inaccessible cave.

And here must have been born the child that inherited the stuff of my dreams, that had moulded into its being all the impressions of my life--or of the life of Big-Tooth, rather, who is my other-self, and not my real self, but who is so real to me that often I am unable to tell what age I am living in.
I often wonder about this line of descent.

I, the modern, am incontestably a man; yet I, Big-Tooth, the primitive, am not a man.
Somewhere, and by straight line of descent, these two parties to my dual personality were connected.

Were the Folk, before their destruction, in the process of becoming men?
And did I and mine carry through this process?
On the other hand, may not some descendant of mine have gone in to the Fire People and become one of them?
I do not know.

There is no way of learning.
