The Jew still spluttered, and moaned, and hesitated.
"Well, then," said Servadac, "if you do not like to lend us your steelyard, do you object to sell it to us?"
Isaac fairly shrieked aloud. "God of Israel!" he ejaculated, "sell my steelyard? Would you deprive me of one of the most indispensable of my means of livelihood? How should I weigh my merchandise without my steelyard--my solitary steelyard, so delicate and so correct?"
The orderly wondered how his master could refrain from strangling the old miser upon the spot; but Servadac, rather amused than otherwise, determined to try another form of persuasion. "Come, Hakkabut, I see that you are not disposed either to lend or to sell your steelyard. What do you say to letting us hire it?"
The Jew's eyes twinkled with a satisfaction that he was unable to conceal. "But what security would you give? The instrument is very valuable;" and he looked more cunning than ever.
"What is it worth? If it is worth twenty francs, I will leave a deposit of a hundred. Will that satisfy you?"
He shook his head doubtfully. "It is very little; indeed, it is too little, your Excellency. Consider, it is the only steelyard in all this new world of ours; it is worth more, much more. If I take your deposit it must be in gold--all gold. But how much do you agree to give me for the hire--the hire, one day?"
"You shall have twenty francs," said Servadac.
"Oh, it is dirt cheap; but never mind, for one day, you shall have it. Deposit in gold money a hundred francs, and twenty francs for the hire." The old man folded his hands in meek resignation.
"The fellow knows how to make a good bargain," said Servadac, as Isaac, after casting a distrustful look around, went out of the cabin.
"Detestable old wretch!" replied the count, full of disgust.
Hardly a minute elapsed before the Jew was back again, carrying his precious steelyard with ostentatious care. It was of an ordinary kind. A spring balance, fitted with a hook, held the article to be weighed; a pointer, revolving on a disc, indicated the weight of the article. Professor Rosette was manifestly right in asserting that such a machine would register results quite independently of any change in the force of attraction. On the earth it would have registered a kilogramme as a kilogramme; here it recorded a different value altogether, as the result of the altered force of gravity.
Gold coinage to the worth of one hundred and twenty francs was handed over to the Jew, who clutched at the money with unmistakable eagerness. The steelyard was committed to the keeping of Ben Zoof, and the visitors prepared to quit the Hansa.
All at once it occurred to the professor that the steelyard would be absolutely useless to him, unless he had the means for ascertaining the precise measurement of the unit of the soil of Gallia which he proposed to weigh. "Something more you must lend me," he said, addressing the Jew. "I must have a measure, and I must have a kilogramme."
"I have neither of them," answered Isaac. "I have neither. I am sorry; I am very sorry." And this time the old Jew spoke the truth. He would have been really glad to do another stroke or two of business upon terms as advantageous as the transaction he had just concluded.
Palmyrin Rosette scratched his head in perplexity, glaring round upon his companions as if they were personally responsible for his annoyance. He muttered something about finding a way out of his difficulty, and hastily mounted the cabin-ladder. The rest followed, but they had hardly reached the deck when the chink of money was heard in the room below. Hakkabut was locking away the gold in one of the drawers.
Back again, down the ladder, scrambled the little professor, and before the Jew was aware of his presence he had seized him by the tail of his slouchy overcoat. "Some of your money! I must have money!" he said.
"Money!" gasped Hakkabut; "I have no money." He was pale with fright, and hardly knew what he was saying.
"Falsehood!" roared Rosette. "Do you think I cannot see?" And peering down into the drawer which the Jew was vainly trying to close, he cried, "Heaps of money! French money! Five-franc pieces! the very thing I want! I must have them!"
The captain and his friends, who had returned to the cabin looked on with mingled amusement and bewilderment.
"They are mine!" shrieked Hakkabut.
"I will have them!" shouted the professor.
"You shall kill me first!" bellowed the Jew.
"No, but I must!" persisted the professor again.
It was manifestly time for Servadac to interfere. "My dear professor," he said, smiling, "allow me to settle this little matter for you."
"Ah! your Excellency," moaned the agitated Jew, "protect me! I am but a poor man--"
"None of that, Hakkabut. Hold your tongue." And, turning to Rosette, the captain said, "If, sir, I understand right, you require some silver five-franc pieces for your operation?"
"Forty," said Rosette, surlily.
"Two hundred francs!" whined Hakkabut.
"Silence!" cried the captain.
"I must have more than that," the professor continued. "I want ten two-franc pieces, and twenty half-francs."
"Let me see," said Servadac, "how much is that in all? Two hundred and thirty francs, is it not?"
"I dare say it is," answered the professor.
"Count, may I ask you," continued Servadac, "to be security to the Jew for this loan to the professor?"
"Loan!" cried the Jew, "do you mean only a loan?"
"Silence!" again shouted the captain.
Count Timascheff, expressing his regret that his purse contained only paper money, begged to place it at Captain Servadac's disposal.
"No paper, no paper!" exclaimed Isaac. "Paper has no currency in Gallia."
"About as much as silver," coolly retorted the count.
"I am a poor man," began the Jew.
"Now, Hakkabut, stop these miserable lamentations of yours, once for all. Hand us over two hundred and thirty francs in silver money, or we will proceed to help ourselves."
Isaac began to yell with all his might: "Thieves! thieves!"
In a moment Ben Zoof's hand was clasped tightly over his mouth. "Stop that howling, Belshazzar!"
"Let him alone, Ben Zoof. He will soon come to his senses," said Servadac, quietly.
When the old Jew had again recovered himself, the captain addressed him. "Now, tell us, what interest do you expect?"
Nothing could overcome the Jew's anxiety to make another good bargain. He began: "Money is scarce, very scarce, you know--"
"No more of this!" shouted Servadac. "What interest, I say, what interest do you ask?"
Faltering and undecided still, the Jew went on. "Very scarce, you know. Ten francs a day, I think, would not be unreasonable, considering--"
The count had no patience to allow him to finish what he was about to say. He flung down notes to the value of several rubles. With a greediness that could not be concealed, Hakkabut grasped them all. Paper, indeed, they were; but the cunning Israelite knew that they would in any case be security far beyond the value of his cash. He was making some eighteen hundred per cent. interest, and accordingly chuckled within himself at his unexpected stroke of business.
The professor pocketed his French coins with a satisfaction far more demonstrative. "Gentlemen," he said, "with these franc pieces I obtain the means of determining accurately both a meter and a kilogramme."
CHAPTER VII. GALLIA WEIGHED
A quarter of an hour later, the visitors to the Hansa had reassembled in the common hall of Nina's Hive.
"Now, gentlemen, we can proceed," said the professor. "May I request that this table may be cleared?"
Ben Zoof removed the various articles that were lying on the table, and the coins which had just been borrowed from the Jew were placed upon it in three piles, according to their value.
The professor commenced. "Since none of you gentlemen, at the time of the shock, took the precaution to save either a meter measure or a kilogramme weight from the earth, and since both these articles are necessary for the calculation on wh
ich we are engaged, I have been obliged to devise means of my own to replace them."
This exordium delivered, he paused and seemed to watch its effect upon his audience, who, however, were too well acquainted with the professor's temper to make any attempt to exonerate themselves from the rebuke of carelessness, and submitted silently to the implied reproach.
"I have taken pains," he continued, "to satisfy myself that these coins are in proper condition for my purpose. I find them unworn and unchipped; indeed, they are almost new. They have been hoarded instead of circulated; accordingly, they are fit to be utilized for my purpose of obtaining the precise length of a terrestrial meter."
Ben Zoof looked on in perplexity, regarding the lecturer with much the same curiosity as he would have watched the performances of a traveling mountebank at a fair in Montmartre; but Servadac and his two friends had already divined the professor's meaning. They knew that French coinage is all decimal, the franc being the standard of which the other coins, whether gold, silver, or copper, are multiples or measures; they knew, too, that the caliber or diameter of each piece of money is rigorously determined by law, and that the diameters of the silver coins representing five francs, two francs, and fifty centimes measure thirty-seven, twenty-seven, and eighteen millimeters respectively; and they accordingly guessed that Professor Rosette had conceived the plan of placing such a number of these coins in juxtaposition that the length of their united diameters should measure exactly the thousand millimeters that make up the terrestrial meter.
The measurement thus obtained was by means of a pair of compasses divided accurately into ten equal portions, or decimeters, each of course 3.93 inches long. A lath was then cut of this exact length and given to the engineer of the Dobryna, who was directed to cut out of the solid rock the cubic decimeter required by the professor.
The next business was to obtain the precise weight of a kilogramme. This was by no means a difficult matter. Not only the diameters, but also the weights, of the French coins are rigidly determined by law, and as the silver five-franc pieces always weigh exactly twenty-five grammes, the united weight of forty of these coins is known to amount to one kilogramme.
"Oh!" cried Ben Zoof; "to be able to do all this I see you must be rich as well as learned."
With a good-natured laugh at the orderly's remark, the meeting adjourned for a few hours. By the appointed time the engineer had finished his task, and with all due care had prepared a cubic decimeter of the material of the comet.
"Now, gentlemen," said Professor Rosette, "we are in a position to complete our calculation; we can now arrive at Gallia's attraction, density, and mass."
Everyone gave him his complete attention.
"Before I proceed," he resumed, "I must recall to your minds Newton's general law, 'that the attraction of two bodies is directly proportional to the product of their masses, and inversely proportional to the square of their distances.'"
"Yes," said Servadac; "we remember that."
"Well, then," continued the professor, "keep it in mind for a few minutes now. Look here! In this bag are forty five-franc pieces--altogether they weigh exactly a kilogramme; by which I mean that if we were on the earth, and I were to hang the bag on the hook of the steelyard, the indicator on the dial would register one kilogramme. This is clear enough, I suppose?"
As he spoke the professor designedly kept his eyes fixed upon Ben Zoof. He was avowedly following the example of Arago, who was accustomed always in lecturing to watch the countenance of the least intelligent of his audience, and when he felt that he had made his meaning clear to him, he concluded that he must have succeeded with all the rest. In this case, however, it was technical ignorance, rather than any lack of intelligence, that justified the selection of the orderly for this special attention.
Satisfied with his scrutiny of Ben Zoof's face, the professor went on. "And now, gentlemen, we have to see what these coins weigh here upon Gallia."
He suspended the money bag to the hook; the needle oscillated, and stopped. "Read it off!" he said.
The weight registered was one hundred and thirty-three grammes.
"There, gentlemen, one hundred and thirty-three grammes! Less than one-seventh of a kilogramme! You see, consequently, that the force of gravity here on Gallia is not one-seventh of what it is upon the earth!"
"Interesting!" cried Servadac, "most interesting! But let us go on and compute the mass."
"No, captain, the density first," said Rosette.
"Certainly," said the lieutenant; "for, as we already know the volume, we can determine the mass as soon as we have ascertained the density."
The professor took up the cube of rock. "You know what this is," he went on to say. "You know, gentlemen, that this block is a cube hewn from the substance of which everywhere, all throughout your voyage of circumnavigation, you found Gallia to be composed--a substance to which your geological attainments did not suffice to assign a name."
"Our curiosity will be gratified," said Servadac, "if you will enlighten our ignorance."
But Rosette did not take the slightest notice of the interruption.
"A substance it is which no doubt constitutes the sole material of the comet, extending from its surface to its innermost depths. The probability is that it would be so; your experience confirms that probability: you have found no trace of any other substance. Of this rock here is a solid decimeter; let us get at its weight, and we shall have the key which will unlock the problem of the whole weight of Gallia. We have demonstrated that the force of attraction here is only one-seventh of what it is upon the earth, and shall consequently have to multiply the apparent weight of our cube by seven, in order to ascertain its proper weight. Do you understand me, goggle-eyes?"
This was addressed to Ben Zoof, who was staring hard at him. "No!" said Ben Zoof.
"I thought not; it is of no use waiting for your puzzle-brains to make it out. I must talk to those who can understand."
The professor took the cube, and, on attaching it to the hook of the steelyard, found that its apparent weight was one kilogramme and four hundred and thirty grammes.
"Here it is, gentlemen; one kilogramme, four hundred and thirty grammes. Multiply that by seven; the product is, as nearly as possible, ten kilogrammes. What, therefore, is our conclusion? Why, that the density of Gallia is just about double the density of the earth, which we know is only five kilogrammes to a cubic decimeter. Had it not been for this greater density, the attraction of Gallia would only have been one-fifteenth instead of one-seventh of the terrestrial attraction."
The professor could not refrain from exhibiting his gratification that, however inferior in volume, in density, at least, his comet had the advantage over the earth.
Nothing further now remained than to apply the investigations thus finished to the determining of the mass or weight. This was a matter of little labor.
"Let me see," said the captain; "what is the force of gravity upon the various planets?"
"You can't mean, Servadac, that you have forgotten that? But you always were a disappointing pupil."
The captain could not help himself: he was forced to confess that his memory had failed him.
"Well, then," said the professor, "I must remind you. Taking the attraction on the earth as 1, that on Mercury is 1.15, on Venus it is.92, on Mars.5, and on Jupiter 2.45; on the moon the attraction is.16, whilst on the surface of the sun a terrestrial kilogramme would weigh 28 kilogrammes."
"Therefore, if a man upon the surface of the sun were to fall down, he would have considerable difficulty in getting up again. A cannon ball, too, would only fly a few yards," said Lieutenant Procope.
"A jolly battle-field for cowards!" exclaimed Ben Zoof.
"Not so jolly, Ben Zoof, as you fancy," said his master; "the cowards would be too heavy to run away."
Ben Zoof ventured the remark that, as the smallness of Gallia secured to its inhabitants such an increase of strength and agility, he was almost sorry that it had not
been a little smaller still.
"Though it could not anyhow have been very much smaller," he added, looking slyly at the professor.
"Idiot!" exclaimed Rosette. "Your head is too light already; a puff of wind would blow it away."
"I must take care of my head, then, and hold it on," replied the irrepressible orderly.
Unable to get the last word, the professor was about to retire, when Servadac detained him.
"Permit me to ask you one more question," he said. "Can you tell me what is the nature of the soil of Gallia?"
"Yes, I can answer that. And in this matter I do not think your impertinent orderly will venture to put Montmartre into the comparison. This soil is of a substance not unknown upon the earth." And speaking very slowly, the professor said: "It contains 70 per cent. of tellurium, and 30 per cent. of gold."
