They were voyaging much slower now, and after another ten days had passed an unexpected change came on. The downpour diminished in severity, and at times the sun broke forth, and for an hour or two the rain would cease entirely, although the sky had a coppery tinge, and at night small stars were not clearly visible.
Cosmo was greatly surprised at this. He could only conclude that the central part of the nebula had been less extensive, though more dense, than he had estimated. It was only thirty-four days since the deluge had recommenced, and unless present appearances were deceptive, its end might be close at hand.
Captain Arms seized the opportunity to make celestial and solar observations which delighted his seaman's heart, and with great glee he informed Cosmo that they were in longitude 88 degrees 20 minutes east, latitude 24 degrees 15 minutes north, and he would stake his reputation as a navigator upon it.
"Almost exactly the location of Moorshedabad, in Bengal," said Cosmo, consulting his chart. "The mighty peak of Kunchingunga is hardly more than two hundred miles toward the north, and Mount Everest, the highest point in the world, is within a hundred miles of that!"
"But you're not going skimming around them!" cried the captain with some alarm.
"I shall, if the sky continues in its present condition, go as far as Darjeeling," replied Cosmo. "Then we can turn eastward and get over upper Burmah and so on into China. From there we can turn north again.
"I think we can manage to get into Tibet somewhere between the ranges. It all depends upon the height of the water, and that I can ascertain exactly by getting a close look at Kunchingunga. I would follow the line of the Brahmaputra River if I dared, but the way is too beset with perils."
"I think you've made a big mistake," said the captain. "Why didn't you come directly across Russia, after first running up to the Black Sea from the Mediterranean, and so straight into Tibet?"
"I begin to think that that's what I ought to have done," responded Cosmo, thoughtfully, "but when we started the water was not high enough to make me sure of that route, and after we got down into Egypt I didn't want to run back. But I guess it would have been better."
"Better a sight than steering among these five-mile peaks," growled Captain Arms. "How high does Darjeeling lie? I don't want to run aground again."
