"You don't mean us to go up in that thing, Challenger?" said he, in an acid voice.

"I mean, my dear Summerlee, to give you such a demonstration of its powers that after seeing it you will, I am sure, have no hesitation in trusting yourself to it."

"You can put it right out of your head now, at once," said Summerlee with decision, "nothing on earth would induce me to commit such a folly. Lord John, I trust that you will not countenance such madness?"

"Dooced ingenious, I call it," said our peer. "I'd like to see how it works."

"So you shall," said Challenger. "For some days I have exerted my whole brain force upon the problem of how we shall descend from these cliffs. We have satisfied ourselves that we cannot climb down and that there is no tunnel. We are also unable to construct any kind of bridge which may take us back to the pinnacle from which we came. How then shall I find a means to convey us? Some little time ago I had remarked to our young friend here that free hydrogen was evolved from the geyser. The idea of a balloon naturally followed. I was, I will admit, somewhat baffled by the difficulty of discovering an envelope to contain the gas, but the contemplation of the immense entrails of these reptiles supplied me with a solution to the problem. Behold the result!"

He put one hand in the front of his ragged jacket and pointed proudly with the other.

By this time the gas-bag had swollen to a goodly rotundity and was jerking strongly upon its lashings.

"Midsummer madness!" snorted Summerlee.

Lord John was delighted with the whole idea. "Clever old dear, ain't he?" he whispered to me, and then louder to Challenger. "What about a car?"

"The car will be my next care. I have already planned how it is to be made and attached. Meanwhile I will simply show you how capable my apparatus is of supporting the weight of each of us."

"All of us, surely?"

"No, it is part of my plan that each in turn shall descend as in a parachute, and the balloon be drawn back by means which I shall have no difficulty in perfecting. If it will support the weight of one and let him gently down, it will have done all that is required of it. I will now show you its capacity in that direction."

He brought out a lump of basalt of a considerable size, constructed in the middle so that a cord could be easily attached to it. This cord was the one which we had brought with us on to the plateau after we had used it for climbing the pinnacle. It was over a hundred feet long, and though it was thin it was very strong. He had prepared a sort of collar of leather with many straps depending from it. This collar was placed over the dome of the balloon, and the hanging thongs were gathered together below, so that the pressure of any weight would be diffused over a considerable surface. Then the lump of basalt was fastened to the thongs, and the rope was allowed to hang from the end of it, being passed three times round the Professor's arm.
