That evening I took a brief walk on the shore near Reykjavik, after which I returned to an early sleep on my bed of coarse planks, where I slept the sleep of the just. When I awoke I heard my uncle speaking loudly in the next room. I rose hastily and joined him. He was talking in Danish with a man of tall stature, and of perfectly Herculean build. This man appeared to be possessed of very great strength. His eyes, which started rather prominently from a very large head, the face belonging to which was simple and naive, appeared very quick and intelligent. Very long hair, which even in England would have been accounted exceedingly red, fell over his athletic shoulders. This native of Iceland was active and supple in appearance, though he scarcely moved his arms, being in fact one of those men who despise the habit of gesticulation common to southern people.  
Everything in this man's manner revealed a calm and phlegmatic temperament. There was nothing indolent about him, but his appearance spoke of tranquillity. He was one of those who never seemed to expect anything from anybody, who liked to work when he thought proper, and whose philosophy nothing could astonish or trouble.
 
I began to comprehend his character, simply from the way in which he listened to the wild and impassioned verbiage of my worthy uncle. While the excellent Professor spoke sentence after sentence, he stood with folded arms, utterly still, motionless to all my uncle's gesticulations. When he wanted to say No he moved his head from left to right; when he acquiesced he nodded, so slightly that you could scarcely see the undulation of his head. This economy of motion was carried to the length of avarice.
 
Judging from his appearance I should have been a long time before I had suspected him to be what he was, a mighty hunter. Certainly his manner was not likely to frighten the game. How, then, did he contrive to get at his prey?
 
My surprise was slightly modified when I knew that this tranquil and solemn personage was only a hunter of the eider duck, the down of which is, after all, the greatest source of the Icelanders' wealth.
 
In the early days of summer, the female of the eider, a pretty sort of duck, builds its nest amid the rocks of the fjords—the name given to all narrow gulfs in Scandinavian countries—with which every part of the island is indented. No sooner has the eider duck made her nest than she lines the inside of it with the softest down from her breast. Then comes the hunter or trader, taking away the nest, the poor bereaved female begins her task over again, and this continues as long as any eider down is to be found.
 
When she can find no more the male bird sets to work to see what he can do. As, however, his down is not so soft, and has therefore no commercial value, the hunter does not take the trouble to rob him of his nest lining. The nest is accordingly finished, the eggs are laid, the little ones are born, and next year the harvest of eider down is again collected.
 
Now, as the eider duck never selects steep rocks or aspects to build its nest, but rather sloping and low cliffs near to the sea, the Icelandic hunter can carry on his trade operations without much difficulty. He is like a farmer who has neither to plow, to sow, nor to harrow, only to collect his harvest.
 
This grave, sententious, silent person, as phlegmatic as an Englishman on the French stage, was named Hans Bjelke. He had called upon us in consequence of the recommendation of M. Fridriksson. He was, in fact, our future guide. It struck me that had I sought the world over, I could not have found a greater contradiction to my impulsive uncle.
 
They, however, readily understood one another. Neither of them had any thought about money; one was ready to take all that was offered him, the other ready to offer anything that was asked. It may readily be conceived, then, that an understanding was soon come to between them.
 
Now, the understanding was, that he was to take us to the village of Stapi, situated on the southern slope of the peninsula of Sneffels, at the very foot of the volcano. Hans, the guide, told us the distance was about twenty-two miles, a journey which my uncle supposed would take about two days.
 
But when my uncle came to understand that they were Danish miles, of eight thousand yards each, he was obliged to be more moderate in his ideas, and, considering the horrible roads we had to follow, to allow eight or ten days for the journey.
 
Four horses were prepared for us, two to carry the baggage, and two to bear the important weight of myself and uncle. Hans declared that nothing ever would make him climb on the back of any animal. He knew every inch of that part of the coast, and promised to take us the very shortest way.
 
His engagement with my uncle was by no means to cease with our arrival at Stapi; he was further to remain in his service during the whole time required for the completion of his scientific investigations, at the fixed salary of three rix-dollars a week, being exactly fourteen shillings and twopence, minus one farthing, English currency. One stipulation, however, was made by the guide—the money was to be paid to him every Saturday night, failing which, his engagement was at an end.
 
The day of our departure was fixed. My uncle wished to hand the eider-down hunter an advance, but he refused in one emphatic word—
 
"Efter."
 
Which being translated from Icelandic into plain English means—"After."
 
The treaty concluded, our worthy guide retired without another word.
 
"A splendid fellow," said my uncle; "only he little suspects the marvelous part he is about to play in the history of the world."
 
"You mean, then," I cried in amazement, "that he should accompany us?"
 
"To the interior of the earth, yes," replied my uncle. "Why not?"
 
There were yet forty-eight hours to elapse before we made our final start. To my great regret, our whole time was taken up in making preparations for our journey. All our industry and ability were devoted to packing every object in the most advantageous manner—the instruments on one side, the arms on the other, the tools here and the provisions there. There were, in fact, four distinct groups.
 
The instruments were of course of the best manufacture:
 
1. A centigrade thermometer of Eigel, counting up to 150 degrees, which to me did not appear half enough—or too much. Too hot by half, if the degree of heat was to ascend so high—in which case we should certainly be cooked—not enough, if we wanted to ascertain the exact temperature of springs or metal in a state of fusion.
 
2. A manometer worked by compressed air, an instrument used to ascertain the upp............
