CHAPTER XV. AN ENIGMA FROM THE SEA

Lieutenant Procope had been left on board in charge of the _Dobryna_,
and on resuming the voyage it was a task of some difficulty to make him
understand the fact that had just come to light. Some hours were spent
in discussion and in attempting to penetrate the mysteries of the
situation.

There were certain things of which they were perfectly certain. They
could be under no misapprehension as to the distance they had positively
sailed from Gourbi Island towards the east before their further progress
was arrested by the unknown shore; as nearly as possible that was
fifteen degrees; the length of the narrow strait by which they had made
their way across that land to regain the open sea was about three miles
and a half; thence onward to the island, which they had been assured,
on evidence that they could not disbelieve, to be upon the site of
Gibraltar, was four degrees; while from Gibraltar to Gourbi Island was
seven degrees or but little more. What was it altogether? Was it not
less than thirty degrees? In that latitude, the degree of longitude
represents eight and forty miles. What, then, did it all amount to?
Indubitably, to less than 1,400 miles. So brief a voyage would bring the
_Dobryna_ once again to her starting-point, or, in other words, would
enable her to complete the circumnavigation of the globe. How changed
the condition of things! Previously, to sail from Malta to Gibraltar by
an eastward course would have involved the passage of the Suez Canal,
the Red Sea, the Indian Ocean, the Pacific, the Atlantic; but what had
happened now? Why, Gibraltar had been reached as if it had been just at
Corfu, and some three hundred and thirty degrees of the earth's circuit
had vanished utterly.

After allowing for a certain margin of miscalculation, the main fact
remained undeniable; and the necessary inference that Lieutenant Procope
drew from the round of the earth being completed in 1,400 miles, was
that the earth's diameter had been reduced by about fifteen sixteenths
of its length.

"If that be so," observed the count, "it accounts for some of the
strange phenomena we witness. If our world has become so insignificant a
spheroid, not only has its gravity diminished, but its rotary speed has
been accelerated; and this affords an adequate explanation of our days
and nights being thus curtailed. But how about the new orbit in which we
are moving?"

He paused and pond
