Moving a considerable distance from the prospector that the needle might not be influenced by its great bulk of iron and steel, I turned the delicate instrument about in every direction.

Always and steadily the needle remained rigidly fixed upon a point straight out to sea, apparently pointing toward a large island some ten or twenty miles distant. This then should be north.

I drew my note-book from my pocket and made a careful topographical sketch of the locality within the range of my vision. Due north lay the island, far out upon the shimmering sea.

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.

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
