Nevertheless, and despite all the manifold difficulties of the descent, along slopes with which our guide was wholly unacquainted, we made considerable progress without accident. One of our great parcels of rope slipped from one of the Iceland porters, and rushed by a short cut to the bottom of the abyss.

By midday we were at the end of our journey. I looked upwards, and saw only the upper orifice of the cone, which served as a circular frame to a very small portion of the sky--a portion which seemed to me singularly beautiful. Should I ever again gaze on that lovely sunlit sky!

The only exception to this extraordinary landscape, was the Peak of Scartaris, which seemed lost in the great void of the heavens.

The bottom of the crater was composed of three separate shafts, through which, during periods of eruption, when Sneffels was in action, the great central furnace sent forth its burning lava and poisonous vapors. Each of these chimneys or shafts gaped open-mouthed in our path. I kept as far away from them as possible, not even venturing to take the faintest peep downwards.

As for the Professor, after a rapid examination of their disposition and characteristics, he became breathless and panting. He ran from one to the other like a delighted schoolboy, gesticulating wildly, and uttering incomprehensible and disjointed phrases in all sorts of languages.

Hans, the guide, and his humbler companions seated themselves on some piles of lava and looked silently on. They clearly took my uncle for a lunatic; and--waited the result.

Suddenly the Professor uttered a wild, unearthly cry. At first I imagined he had lost his footing, and was falling headlong into one of the yawning gulfs. Nothing of the kind. I saw him, his arms spread out to their widest extent, his legs stretched apart, standing upright before an enormous pedestal, high enough and black enough to bear a gigantic statue of Pluto. His attitude and mien were that of a man utterly stupefied. But his stupefaction was speedily changed to the wildest joy.

"Harry! Harry! come here!" he cried; "make haste--wonderful--wonderful!"

Unable to understand what he meant, I turned to obey his commands. Neither Hans nor the other Icelanders moved a step.

"Look!" said the Professor, in something of the manner of the French general, pointing out the pyramids to his army.

And fully partaking his stupefaction, if not his joy, I read on the eastern side of the huge block of stone, the same characters, half eaten away by the corrosive action of time, the name, to me a thousand times accursed--

"Arne Saknussemm!" cried my uncle, "now, unbeliever, do you begin to have faith?"

It was totally impossible for me to answer a single word. I went back to my pile of lava, in a state of silent awe. The evidence was unanswerable, overwhelming!

In a few moments, however, my thoughts were far away, back in my German home, with Gretchen and the old cook. What would I have given for one of my cousin's smiles, for one of the ancient domestic's omelettes, and for my own feather bed!

How long I remained in this state I know not. All I can say is, that when at last I raised my head from between my hands, there remained at the bottom of the crater only myself, my uncle and Hans. The Icelandic porters had been dismissed and were now descending the exterior slopes of Mount Sneffels, on their way to Stapi. How heartily did I wish myself with them!

Hans slept tranquilly at the foot of a rock in a kind of rill of lava, where he had made himself a rough and ready bed. MY uncle was walking about the bottom of the crater like a wild beast in a cage. I had no desire, neither had I the strength, to move from my recumbent position. Taking example by the guide, I gave way to a kind of painful somnolency, during which I seemed both to hear and feel continued heavings and shudderings in the mountain.

In this way we passed our first night in the interior of a crater.

Next morning, a grey, cloudy, heavy sky hung like a funereal pall over the summit of the volcanic cone. I did not notice it so much from the obscurity that reigned around us, as from the rage with which my uncle was devoured.

I fully understood the reason, and again a glimpse of hope made my heart leap with joy. I will briefly explain the cause.

Of the three openings which yawned beneath our steps, only one could have been followed by the adventurous Saknussemm. According to the words of the learned Icelander, it was only to be known by that one particular mentioned in the cryptograph, that the shadow of Scartaris fell upon it, just touching its mouth in the last days of the month of June.

We were, in fact, to consider the pointed peak as the stylus of an immense sun-dial, the shadow of which pointed on one given day, like the inexorable finger of fate, to the yawning chasm which led into the interior of the earth.

Now, as often happens in these regions, should the sun fail to burst through the clouds, no shadow. Consequently, no chance of discovering the right aperture. We had already reached the 25th June. If the kindly heavens would only remain densely clouded for six more days, we should have to put off our voyage of discovery for another year, when certainly there would be one person fewer in the party. I already had sufficient of the mad and monstrous enterprise.

It would be utterly impossible to depict the impotent rage of Professor Hardwigg. The day passed away, and not the faintest outline of a shadow could be seen at the bottom of the crater. Hans the guide never moved from his place. He must have been curious to know what we were about, if indeed he could believe we were about anything. As for my uncle, he never addressed a word to me. He was nursing his wrath to keep it warm! His eyes fixed on the black and foggy atmosphere, his complexion hideous with suppressed passion. Never had his eyes appeared so fierce, his nose so aquiline, his mouth so hard and firm.

On the 26th no change for the better. A mixture of rain and snow fell during the whole day. Hans very quietly built himself a hut of lava into which he retired like Diogenes into his tub. I took a malicious delight in watching the thousand little cascades that flowed down the side of the cone, carrying with them at times a stream of stones into the "vasty deep" below.

My uncle was almost frantic: to be sure, it was enough to make even a patient man angry. He had reached to a certain extent the goal of his desires, and yet he was likely to be wrecked in port.

But if the heavens and the elements are capable of causing us much pain and sorrow, there are two sides to a medal. And there was reserved for Professor Hardwigg a brilliant and sudden surprise which was to compensate him for all his sufferings.

Next day the sky was still overcast, but on Sunday, the 28th, the last day but two of the month, with a sudden change of wind and a new moon there came a change of weather. The sun poured its beaming rays to the very bottom of the crater.

Each hillock, every rock, every stone, every asperity of the soil had its share of the luminous effulgence, and its shadow fell heavily on the soil. Among others, to his insane delight, the shadow of Scartaris was marked and clear, and moved slowly with the radiant start of day.

My uncle moved with it in a state of mental ecstasy.

At twelve o'clock exactly, when the sun had attained its highest altitude for the day, the shadow fell upon the edge of the central pit!

"Here it is," gasped the Professor in an agony of joy, "here it is--we have found it. Forward, my friends, into the Interior of the Earth."

I looked curiously at Hans to see what reply he would make to this terrific announcement.

"Forut," said the guide tranquilly.

"Forward it is," answered my uncle, who was now in the seventh heaven of delight.
