hemisphere, where her plains, or _seas_ as they are called, are immense,
and her mountains are comparatively rare. This, of course, would be so
much the more favorable, if, as was to be apprehended, the lunar
atmosphere was confined exclusively to the low lands.

"Besides," as Ardan observed, "a plain is a more suitable landing place
than a mountain. A Selenite deposited on the top of Mount Everest or
even on Mont Blanc, could hardly be considered, in strict language, to
have arrived on Earth."

"Not to talk," added M'Nicholl, "of the comfort of the thing! When you
land on a plain, there you are. When you land on a peak or on a steep
mountain side, where are you? Tumbling over an embankment with the train
going forty miles an hour, would be nothing to it."

"Therefore, Captain Barbican," cried the Frenchman, "as we should like
to appear before the Selenites in full skins, please land us in the snug
though unromantic North. We shall have time enough to break our necks in
the South."

Barbican made no reply to his companions, because a new reflection had
begun to trouble him, to talk about which would have done no good. There
was certainly something wrong. The Projectile was evidently heading
towards the northern hemisphere of the Moon. What did this prove?
Clearly, a deviation resulting from some cause. The bullet, lodged,
aimed, and fired with the most careful mathematical precision, had been
calculated to reach the very centre of the Moon's disc. Clearly it was
not going to the centre now. What could have produced the deviation?
This Barbican could not tell; nor could he even determine its extent,
having no points of sight by which to make his observations. For the
