"Oh, that's perfectly safe," responded Cosmo. "Darjeeling is only about 7,350 feet above the old sea-level. I think we can go almost to the foot of Kunchingunga without any danger."

"Well, the name sounds dangerous enough in itself," said the captain, "but I suppose you'll have your way. Give me the bearings and we'll be off."

They took two days to get to the location of Darjeeling, for at times the sky darkened and the rain came down again in tremendous torrents. But these spells did not last more than two or three hours, and the weather cleared between them.

As soon as they advanced beyond Darjeeling, keeping a sharp outlook for Kunchingunga, Cosmo began to perceive the error of his calculation of the height of the flood.

The mountain should still have projected more than three thousand feet above the waves, allowing that the average rise during the thirty-six days since the recommencement of the flood had been six hundred feet a day.

But, in fact, they did not see it at all, and thought at first that it had been totally submerged. At last they found it, a little rocky island, less than two hundred feet above the water, according to Cosmo's careful measure, made from a distance of a quarter of a mile.

"This is great news for us," he exclaimed, as soon as he had completed the work. "This will save us a long journey round. The water must now stand at about 27,900 feet, and although there are a considerable number of peaks in the Himalayas approaching such an elevation, there are only three or four known to reach or exceed it, of which Kunchingunga is one.

"We can, then, run right over the roof of the world, and there we'll be, in Tibet. Then we can determine from what side it is safest to approach Mount Everest, for I am very desirous to get near that celebrated peak, and, if possible, see it go under."

"But the weather isn't safe yet," objected Captain Arms. "Suppose we should be caught in another downpour, and everything black about us! I'm not going to navigate this ship by searchlight among mountains twenty-eight thousand feet tall, when the best beam that ever shot from a mirror won't show an object a hundred fathoms away."

"Very well," Cosmo replied, "we'll circle around south for a few days and see what will happen. I think myself that it's not quite over yet. The fact is, I hope it isn't, for now that it has gone so far, I'd like to see the top-knot of the earth covered."
