Four horses were to be placed at our disposal — two to carry him and me, two for the baggage. Hans, as was his custom, would go on foot. He knew all that part of the coast perfectly, and promised to take us the shortest way.

His engagement was not to terminate with our arrival at Stapi; he was to continue in my uncle's service for the whole period of his scientific researches, for the remuneration of three rixdales a week (about twelve shillings), but it was an express article of the covenant that his wages should be counted out to him every Saturday at six o'clock in the evening, which, according to him, was one indispensable part of the engagement.

The start was fixed for the 16th of June. My uncle wanted to pay the hunter a portion in advance, but he refused with one word:

"Efter," said he.

"After," said the Professor for my edification.

The treaty concluded, Hans silently withdrew.

"A famous fellow," cried my uncle; "but he little thinks of the marvellous part he has to play in the future."

"So he is to go with us as far as —"

"As far as the centre of the earth, Axel."

Forty-eight hours were left before our departure; to my great regret I had to employ them in preparations; for all our ingenuity was required to pack every article to the best advantage; instruments here, arms there, tools in this package, provisions in that: four sets of packages in all.

The instruments were:

An Eigel's centigrade thermometer, graduated up to 150 degrees (302 degrees Fahr.), which seemed to me too much or too little. Too much if the internal heat was to rise so high, for in this case we should be baked, not enough to measure the temperature of springs or any matter in a state of fusion.

An aneroid barometer, to indicate extreme pressures of the atmosphere. An ordinary barometer would not have answered the purpose, as the pressure would increase during our descent to a point which the mercurial barometer would not register.

A chronometer, made by Boissonnas, jun., of Geneva, accurately set to the meridian of Hamburg.

Two compasses, viz., a common compass and a dipping needle.

A night glass.

Two of Ruhmkorff's apparatus, which, by means of an electric current, supplied a safe and handy portable light.

The arms consisted of two of Purdy's rifles and two brace of pistols. But what did we want arms for? We had neither savages nor wild beasts to fear, I supposed. But my uncle seemed to believe in his arsenal as in his instruments, and more especially in a considerable quantity of gun cotton, which is unaffected by moisture, and the explosive force of which exceeds that of gunpowder.

The tools comprised two pickaxes, two spades, a silk ropeladder, three iron-tipped sticks, a hatchet, a hammer, a dozen wedges and iron spikes, and a long knotted rope. Now this was a large load, for the ladder was 300 feet long.

And there were provisions too: this was not a large parcel, but it was comforting to know that of essence of beef and biscuits there were six months' consumption. Spirits were the only liquid, and of water we took none; but we had flasks, and my uncle depended on springs from which to fill them. Whatever objections I hazarded as to their quality, temperature, and even absence, remained ineffectual.

To complete the exact inventory of all our travelling accompaniments, I must not forget a pocket medicine chest, containing blunt scissors, splints for broken limbs, a piece of tape of unbleached linen, bandages and compresses, lint, a lancet for bleeding, all dreadful articles to take with one. Then there was a row of phials containing dextrine, alcoholic ether, liquid acetate of lead, vinegar, and ammonia drugs which afforded me no comfort. Finally, all the articles needful to supply Ruhmkorff's apparatus.
