"What was that?"
"This is it. In 1771 the body of a rhinoceros was found on the shore of the Arctic Sea, and in 1799 that of an elephant on the coast of Siberia. How did the animals of warm countries happen to be found in these latitudes? Thereupon there was much commotion among geologists, who were not so wise as a Frenchman, M. Elie de Beaumont, has been since. He showed that these animals used to live in rather high latitudes, and that the streams and rivers simply carried their bodies to the places where they were found. But do you know the explanation which scientific men gave before this one?"
"Scientific men are capable of anything," said Altamont.
"Yes, in explanation of a fact; well, they imagined that the Pole used to be at the equator and the equator at the Pole."
"Bah!"
"It was exactly what I tell you. Now, if it had been so, since the earth is flattened more than five leagues at the pole, the seas, carried to the equator by centrifugal force, would have covered mountains twice as high as the Himalayas; all the countries near the polar circle, Sweden, Norway, Russia, Siberia, Greenland, and New Britain, would have been buried in five leagues of water, while the regions at the equator, having become the pole, would have formed plateaus fifteen leagues high!"
"What a change!" said Johnson.
"O, that made no difference to scientific men!"
"And how did they explain the alteration?" asked Altamont.
"They said it was due to the shock of collision with a comet. The comet is the deus ex machina; whenever one comes to a difficult question in cosmography, a comet is lugged in. It is the most obliging of the heavenly bodies, and at the least sign from a scientific man it disarranges itself to arrange everything."
