Another reason which Sag-Harbor (he went by that name) urged for his want of faith in this matter of the prophet, was something obscurely in reference to his incarcerated body and the whale’s gastric juices. But this objection likewise falls to the ground, because a German exegetist supposes that Jonah must have taken refuge in the floating body of a _dead_ whale—even as the French soldiers in the Russian campaign turned their dead horses into tents, and crawled into them. Besides, it has been divined by other continental commentators, that when Jonah was thrown overboard from the Joppa ship, he straightway effected his escape to another vessel near by, some vessel with a whale for a figure-head; and, I would add, possibly called “The Whale,” as some craft are nowadays christened the “Shark,” the “Gull,” the “Eagle.” Nor have there been wanting learned exegetists who have opined that the whale mentioned in the book of Jonah merely meant a life-preserver—an inflated bag of wind—which the endangered prophet swam to, and so was saved from a watery doom. Poor Sag-Harbor, therefore, seems worsted all round. But he had still another reason for his want of faith. It was this, if I remember right: Jonah was swallowed by the whale in the Mediterranean Sea, and after three days he was vomited up somewhere within three days’ journey of Nineveh, a city on the Tigris, very much more than three days’ journey across from the nearest point of the Mediterranean coast. How is that?
