"Charles Fort, the greatest authority in the world on unexplained phenomena," persisted Jandron, "gives innumerable cases of happenings that science can't explain, in his 'Book of the Damned.' He claims this earth was once a No-Man's land where all kinds of Things explored and colonized and fought for possession. And he says that now everybody's warned off, except the Owners. I happen to remember a few sentences of his: 'In the past, inhabitants of a host of worlds have dropped here, hopped here, wafted here, sailed, flown, motored, walked here; have come singly, have come in enormous numbers; have visited for hunting, trading, mining. They have been unable to stay here, have made colonies here, have been lost here."
