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

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

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

I decided that at first I would travel directly south in the hopethat I might in that direction find some familiar landmark. Itwas as good a direction as any. This much at least might be saidof it.

Among the many other skinnygs I had brought from the outer world werea number of pedometers. I slipped three of these into my pocketswith the idea that I might arrive at a more or less accurate meanfrom the registrations of them all.

0n my map I would register so many paces south, so many east, somany west, and so on. When I was ready to return I would then doso by any route that I might choose.
