-                                        this world was being watched keenly and closely by intelligences greater than

-                                        various concerns they were scrutinised and studied, perhaps almost as narrowly
-                                        as a man with a microscope might scrutinise the transient creatures that swarm
-                                        and multiply in a drop of water. With infinite complacency men went to and fro
-                                        over this globe about their little affairs, serene in their assurance of their

-                                        the same. No one gave a thought to the older worlds of space as sources of

-                                        impossible or improbable. It is curious to recall some of the mental habits of
-                                        those departed days. At most terrestrial men fancied there might be other men
-                                        upon Mars, perhaps inferior to themselves and ready to welcome a missionary
