The publisher of this volume is proud to put upon the market a book of
such high value and dignity. It is quite unusual for the subscription
book market to see such a princely book come into its midst. Here we
have ten dollars worth of _new ideas_, packed into cream form, all for
one dollar, and we positively assert that nothing like it can be found
anywhere in literature. _Great books have no companions._

The illustrations are from the masterly hands of an artist of special
merit for this class of work. He happily places himself into the midst
of other worlds in order to draw the beautiful pictures that illustrate
and adorn this volume. The illustrations are well worth careful
examination and when studied in connection with the reading matter they
are seen in their greatest beauty and value. _The Publishers_

CHAPTER I.

Are There More Worlds Than One?


Our world is large enough to excite our interest and invite our study
until we close our eyes in death. Yet there are countless other orbs
scattered through the solar system and throughout the vast stretches of
the starry heavens. Some of these worlds are smaller than ours, but the
majority of them are hundreds or thousands of times larger.
