He discovered that there was a mountain north of the Gulf of Akaba having an elevation of 3,450 feet, and since this was 220 feet higher than Monte Lauro, in Sicily, on which the Ark had grounded, he counted on it as a gage which would serve his purpose.
So they passed almost directly over Suez, and about 120 miles farther east they found the mountain they sought, rising to the west of the Wadi el Arabia, a continuation of the depression at whose deepest point lay the famous "Dead Sea," so often spoken of in the books of former times.
Here Cosmo was able to make a very accurate estimate from the height of the peak above the water, and he was gratified to find that the recession had not continued. The level of the water appeared to be exactly the same as when they made their unfortunate excursion in the direction of smoking Etna.
"It's all right," he said to Captain Arms. "We can get over into the Syrian desert without much danger, although we must go slowly and carefully until we are well past these ranges that come down from the direction of the Dead Sea. After that I do not see that there is anything in our way until we reach the ancient plains of Babylon."
King Richard, who was full of the history of the Crusades, as well as of Bible narratives, wished to have the Ark turn northward, so that they might sail over Jerusalem, and up the Valley of the Jordan within sight of Mount Hermon and the Lebanon range.
Cosmo had had enough of that kind of adventure, while Captain Arms declared that he would resign on the spot if there was to be any more "fool navigating on mountain tops." But there were many persons in the Ark who would have been very glad if King Richard's suggestion had been carried out.
The feelings of some were deeply stirred when they learned that they were now crossing the lower end of Palestine, and that the scenes of so many incidents in the history of Abraham, Moses, and Joshua lay buried beneath the blue water, whose almost motionless surface was marked with a broad trail of foaming bubbles in the wake of the immense vessel.
Cosmo greatly regretted the absence of the submersible when they were picking their way over this perilous region, but they encountered no real difficulty, and at length found, by celestial observations, that they were beyond all dangers and safely arrived over the deeply submerged desert.
They kept on for several days toward the rising sun, and then Captain Arms announced that the observations showed that they were over the site of Babylon.
This happened just at the time of the midday dinner, and over the dessert Cosmo seized the opportunity to make a little speech, which could be heard by all in the saloon.
