a preference to one over all the rest. Yet, certainly, even amid Verne's
remarkable works, his "Off on a Comet" must be given high rank. Perhaps this
story will be remembered when even "Round the World in Eighty Days"
and "Michael Strogoff" have been obliterated by centuries of time.
At least, of the many books since written upon the same theme as Verne's,
no one has yet succeeded in equaling or even approaching it.

In one way "Off on a Comet" shows a marked contrast to Verne's earlier books.
Not only does it invade a region more remote than even the "Trip to the Moon,"
but the author here abandons his usual scrupulously scientific attitude.
In order that he may escort us through the depths of immeasurable space,
show us what astronomy really knows of conditions there and upon
the other planets, Verne asks us to accept a situation frankly impossible.
The earth and a comet are brought twice into collision without mankind
in general, or even our astronomers, becoming conscious of the fact.
Moreover several people from widely scattered places are carried
off by the comet and returned uninjured. Yet further, the comet
snatches for the convenience of its travelers, both air and water.
Little, useful tracts of earth are picked up and, as it were,
turned over and clapped down right side up again upon the comet's surface.
Even ships pass uninjured through this remarkable somersault.
These events all belong frankly to the realm of fairyland.

If the situation were reproduced in actuality, if ever
a comet should come into collision with the earth,
we can conceive two scientifically possible results.
If the comet were of such attenuation, such almost infinitesimal
mass as some of these celestial wanderers seem to be, we can
imagine our earth self-protective and possibly unharmed.
If, on the other hand, the comet had even a hundredth part
