I had made a start! I cannot tell you what a sense of relief was imparted to me by the simple fact that there was at least one spot within Pellucidar with a familiar name and a place upon a map.

It was with almost childish joy that I made a little circle in my note-book and traced the word Greenwich beside it.

Now I felt I might start out upon my search with some assurance of finding my way back again to the prospector.

I decided that at first I would travel directly south in the hope that I might in that direction find some familiar landmark. It was as good a direction as any. This much at least might be said of it.

Among the many other things I had brought from the outer world were a number of pedometers. I slipped three of these into my pockets with the idea that I might arrive at a more or less accurate mean from the registrations of them all.

On my map I would register so many paces south, so many east, so many west, and so on. When I was ready to return I would then do so by any route that I might choose.

I also strapped a considerable quantity of ammunition across my shoulders, pocketed some matches, and hooked an aluminum fry-pan and a small stew-kettle of the same metal to my belt.

I was ready—ready to go forth and explore a world!

Ready to search a land area of 124,110,000 square miles for my friends, my incomparable mate, and good old Perry!

And so, after locking the door in the outer shell of the prospector, I set out upon my quest. Due south I traveled, across lovely valleys thick-dotted with grazing herds.
