"Nothing at all, my boy. It is only the result of the fatigue of the last few days--that is all."

"You appear--if I may be allowed to say so--to be very jolly this morning," I said.

"Delighted, my dear boy, delighted. Was never happier in my life. We have at last reached the wished-for port."

"The end of our expedition?" cried I, in a tone of considerable surprise.

"No; but to the confines of that sea which I began to fear would never end, but go round the whole world. We will now tranquilly resume our journey by land, and once again endeavor to dive into the centre of the earth."

"My dear uncle," I began, in a hesitating kind of way, "allow me to ask you one question."

"Certainly, Harry; a dozen if you think proper."

"One will suffice. How about getting back?" I asked.

"How about getting back? What a question to ask. We have not as yet reached the end of our journey."

"I know that. All I want to know is how you propose we shall manage the return voyage?"

"In the most simple manner in the world," said the imperturbable Professor. "Once we reach the exact centre of this sphere, either we shall find a new road by which to ascend to the surface, or we shall simply turn round and go back by the way we came. I have every reason to believe that while we are traveling forward, it will not close behind us."

"Then one of the first matters to see to will be to repair the raft,"

was my rather melancholy response.

"Of course. We must attend to that above all things," continued the Professor.

"Then comes the all-important question of provisions," I urged. "Have we anything like enough left to enable us to accomplish such great, such amazing, designs as you contemplate carrying out?"

"I have seen into the matter, and my answer is in the affirmative. Hans is a very clever fellow, and I have reason to believe that he has saved the greater part of the cargo. But the best way to satisfy your scruples is to come and judge for yourself."

Saying which, he led the way out of the kind of open grotto in which we had taken shelter. I had almost begun to hope that which I should rather have feared, and this was the impossibility of such a shipwreck leaving even the slightest signs of what it had carried as freight. I was, however, thoroughly mistaken.

As soon as I reached the sh.o.r.es of this inland sea, I found Hans standing gravely in the midst of a large number of things laid out in complete order. My uncle wrung his hands with deep and silent grat.i.tude.

His heart was too full for speech.

This man, whose superhuman devotion to his employers I not only never saw surpa.s.sed, nor even equaled, had been hard at work all the time we slept, and at the risk of his life had succeeded in saving the most precious articles of our cargo.

Of course, under the circ.u.mstances, we necessarily experienced several severe losses. Our weapons had wholly vanished. But experience had taught us to do without them. The provision of powder had, however, remained intact, after having narrowly escaped blowing us all to atoms in the storm.

"Well," said the Professor, who was now ready to make the best of everything, "as we have no guns, all we have to do is to give up all idea of hunting."

"Yes, my dear sir, we can do without them, but what about all our instruments?"

"Here is the manometer, the most useful of all, and which I gladly accept in lieu of the rest. With it alone I can calculate the depth as we proceed; by its means alone I shall be able to decide when we have reached the centre of the earth. Ha, ha! but for this little instrument we might make a mistake, and run the risk of coming out at the antipodes!"

All this was said amid bursts of unnatural laughter.

"But the compa.s.s," I cried, "without that what can we do?"

"Here it is, safe and sound!" he cried, with real joy, "ah, ah, and here we have the chronometer and the thermometers. Hans the hunter is indeed an invaluable man!"

It was impossible to deny this fact. As far as the nautical and other instruments were concerned, nothing was wanting. Then on further examination, I found ladders, cords, pickaxes, crowbars, and shovels, all scattered about on the sh.o.r.e.

There was, however, finally the most important question of all, and that was, provisions.

"But what are we to do for food?" I asked.

"Let us see to the commissariat department", replied my uncle gravely.

The boxes which contained our supply of food for the voyage were placed in a row along the strand, and were in a capital state of preservation; the sea had in every case respected their contents, and to sum up in one sentence, taking into consideration, biscuits, salt meat, Schiedam and dried fish, we could still calculate on having about four months'

supply, if used with prudence and caution.

"Four months," cried the sanguine Professor in high glee. "Then we shall have plenty of time both to go and to come, and with what remains I undertake to give a grand dinner to my colleagues of the Johanneum."

I sighed. I should by this time have become used to the temperament of my uncle, and yet this man astonished me more and more every day. He was the greatest human enigma I ever had known.

"Now," he, "before we do anything else, we must lay in a stock of fresh water. The rain has fallen in abundance, and filled the hollows of the granite. There is a rich supply of water, and we have no fear of suffering from thirst, which in our circ.u.mstances is of the last importance. As for the raft, I shall recommend Hans to repair it to the best of his abilities; though I have every reason to believe we shall not require it again."

"How is that?" I cried, more amazed than ever at my uncle's style of reasoning.

"I have an idea, my dear boy; it is none other than this simple fact; we shall not come out by the same opening as that by which we entered."

I began to look at my uncle with vague suspicion. An idea had more than once taken possession of me; and this was, that he was going mad. And yet, little did I think how true and prophetic his words were doomed to be.

"And now," he said, "having seen to all these matters of detail, to breakfast."

I followed him to a sort of projecting cape, after he had given his last instructions to our guide. In this original position, with dried meat, biscuit, and a delicious cup of tea, we made a satisfactory meal--I may say one of the most welcome and pleasant I ever remember. Exhaustion, the keen atmosphere, the state of calm after so much agitation, all contributed to give me an excellent appet.i.te. Indeed, it contributed very much to producing a pleasant and cheerful state of mind.

While breakfast was in hand, and between the sips of warm tea, I asked my uncle if he had any idea of how we now stood in relation to the world above.

"For my part," I added, "I think it will be rather difficult to determine."

"Well, if we were compelled to fix the exact spot," said my uncle, "it might be difficult, since during the three days of that awful tempest I could keep no account either of the quickness of our pace, or of the direction in which the raft was going. Still, we will endeavor to approximate to the truth. We shall not, I believe, be so very far out."

"Well, if I recollect rightly," I replied, "our last observation was made at the geyser island."

"Harry's Island, my boy! Harry's Island. Do not decline the honor of having named it; given your name to an island discovered by us, the first human beings who trod it since the creation of the world!"

"Let it be so, then. At Harry's Island we had already gone over two hundred and seventy leagues of sea, and we were, I believe, about six hundred leagues, more or less, from Iceland."

"Good. I am glad to see that you remember so well. Let us start from that point, and let us count four days of storm, during which our rate of traveling must have been very great. I should say that our velocity must have been about eighty leagues to the twenty-four hours."

I agreed that I thought this a fair calculation. There were then three hundred leagues to be added to the grand total.

"Yes, and the Central Sea must extend at least six hundred leagues from side to side. Do you know, my boy, Harry, that we have discovered an inland lake larger than the Mediterranean?"

"Certainly, and we only know of its extent in one way. It may be hundreds of miles in length."

"Very likely."
