All Around the Moon by Jules Verne (beach books TXT) 📗

Michael, Michael, why didn't you know the Captain earlier?"

But the Captain was now too deeply interested in a hot discussion with Barbican to notice that the Frenchman was only funning him. Which of the two curves had been the one most probably taken by the Projectile? Barbican maintained it was the parabolic; M'Nicholl insisted that it was the hyperbolic. Their tempers were not improved by the severe cold, and both became rather excited in the dispute. They drew so many lines on the table, and crossed them so often with others, that nothing was left at last but a great blot. They covered bits of paper with x's and y's, which they read out like so many classic passages, shouting them, declaiming them, drawing attention to the strong points by gesticulation so forcible and voice so loud that neither of the disputants could hear a word that the other said. Possibly the very great difference in temperature between the external air in contact with their skin and the blood coursing through their veins, had given rise to magnetic currents as potential in their effects as a superabundant supply of oxygen. At all events, the language they soon began to employ in the enforcement of their arguments fairly made the Frenchman's hair stand on end.

"You probably forget the important difference between a directrix and an axis," hotly observed Barbican.

"I know what an abscissa is, any how!" cried the Captain. "Can you say as much?"

"Did you ever understand what is meant by a double ordinate?" asked Barbican, trying to keep cool.

"More than you ever did about a transverse and a conjugate!" replied the Captain, with much asperity.

"Any one not convinced at a glance that this eccentricity is equal to unity, must be blind as a bat!" exclaimed Barbican, fast losing his ordinary urbanity.

"Less than unity, you mean! If you want spectacles, here are mine!" shouted the Captain, angrily tearing them off and offering them to his adversary.

"Dear boys!" interposed Ardan—

—"The eccentricity is equal to unity!" cried Barbican.

—"The eccentricity is less than unity!" screamed M'Nicholl.

"Talking of eccentricity—" put in Ardan.

—"Therefore it's a parabola, and must be!" cried Barbican, triumphantly.

—"Therefore it's hyperbola and nothing shorter!" was the Captain's quite as confident reply.

"For gracious sake!—" resumed Ardan.

"Then produce your asymptote!" exclaimed Barbican, with an angry sneer.

"Let us see the symmetrical point!" roared the Captain, quite savagely.

"Dear boys! old fellows!—" cried Ardan, as loud as his lungs would let him.

"It's useless to argue with a Mississippi steamboat Captain," ejaculated Barbican; "he never gives in till he blows up!"

"Never try to convince a Yankee schoolmaster," replied M'Nicholl; "he has one book by heart and don't believe in any other!"

"Here, friend Michael, get me a cord, won't you? It's the only way to convince him!" cried Barbican, hastily turning to the Frenchman.

"Hand me over that ruler, Ardan!" yelled the Captain. "The heavy one! It's the only way now left to bring him to reason!"

"Look here, Barbican and M'Nicholl!" cried Ardan, at last making himself heard, and keeping a tight hold both on the cord and the ruler. "This thing has gone far enough! Come. Stop your talk, and answer me a few questions. What do you want of this cord, Barbican?"

"To describe a parabolic curve!"

"And what are you going to do with the ruler, M'Nicholl!"

"To help draw a true hyperbola!"

"Promise me, Barbican, that you're not going to lasso the Captain!"

"Lasso the Captain! Ha! ha! ha!"

"You promise, M'Nicholl, that you're not going to brain the President!"

"I brain the President! Ho! ho! ho!"

"I want merely to convince him that it is a parabola!"

"I only want to make it clear as day that it is hyperbola!"

"Does it make any real difference whether it is one or the other?" yelled Ardan.

"The greatest possible difference—in the Eye of Science."

"A radical and incontrovertible difference—in the Eye of Science!"

"Oh! Hang the Eye of Science—will either curve take us to the Moon?"

"No!"

"Will either take us back to the Earth?"

"No!"

"Will either take us anywhere that you know of?"

"No!"

"Why not?"

"Because they are both open curves, and therefore can never end!"

"Is it of the slightest possible importance which of the two curves controls the Projectile?"

"Not the slightest—except in the Eye of Science!"

"Then let the Eye of Science and her parabolas and hyperbolas, and conjugates, and asymptotes, and the rest of the confounded nonsensical farrago, all go to pot! What's the use of bothering your heads about them here! Have you not enough to trouble you otherwise? A nice pair of scientists you are? 'Stanislow' scientists, probably. Do real scientists lose their tempers for a trifle? Am I ever to see my ideal of a true scientific man in the flesh? Barbican came very near realizing my idea perfectly; but I see that Science just has as little effect as Culture in driving the Old Adam out of us! The idea of the only simpleton in the lot having to lecture the others on propriety of deportment! I thought they were going to tear each other's eyes out! Ha! Ha! Ha! It's impayable! Give me that cord, Michael! Hand me the heavy ruler, Ardan! It's the only way to bring him to reason! Ho! Ho! Ho! It's too good! I shall never get over it!" and he laughed till his sides ached and his cheeks streamed.

His laughter was so contagious, and his merriment so genuine, that there was really no resisting it, and the next few minutes witnessed nothing but laughing, and handshaking and rib-punching in the Projectile—though Heaven knows there was very little for the poor fellows to be merry about. As they could neither reach the Moon nor return to the Earth, what was to befall them? The immediate outlook was the very reverse of exhilarating. If they did not die of hunger, if they did not die of thirst, the reason would simply be that, in a few days, as soon as their gas was exhausted, they would die for want of air, unless indeed the icy cold had killed them beforehand!

By this time, in fact, the temperature had become so exceedingly cold that a further encroachment on their little stock of gas could be put off no longer. The light, of course, they could manage to do without; but a little heat was absolutely necessary to prevent them from freezing to death. Fortunately, however, the caloric developed by the Reiset and Regnault process for purifying the air, raised the internal temperature of the Projectile a little, so that, with an expenditure of gas much less than they had expected, our travellers were able to maintain it at a degree capable of sustaining human life.

By this time, also, all observations through the windows had become exceedingly difficult. The internal moisture condensed so thick and congealed so hard on the glass that nothing short of continued friction could keep up its transparency. But this friction, however laborious they might regard it at other times, they thought very little of just now, when observation had become far more interesting and important than ever.

If the Moon had any atmosphere, our travellers were near enough now to strike any meteor that might be rushing through it. If the Projectile itself were floating in it, as was possible, would not such a good conductor of sound convey to their ears the reflexion of some lunar echo, the roar of some storm raging among the mountains, the rattling of some plunging avalanche, or the detonations of some eructating volcano? And suppose some lunar Etna or Vesuvius was flashing out its fires, was it not even possible that their eye could catch a glimpse of the lurid gleam? One or two facts of this kind, well attested, would singularly elucidate the vexatious question of a lunar atmosphere, which is still so far from being decided. Full of such thoughts and intensely interested in them, Barbican, M'Nicholl and Ardan, patient as astronomers at a transit of Venus, watched steadily at their windows, and allowed nothing worth noticing to escape their searching gaze.

Ardan's patience first gave out. He showed it by an observation natural enough, for that matter, to a mind unaccustomed to long stretches of careful thought:

"This darkness is absolutely killing! If we ever take this trip again, it must be about the time of the New Moon!"

"There I agree with you, Ardan," observed the Captain. "That would be just the time to start. The Moon herself, I grant, would be lost in the solar rays and therefore invisible all the time of our trip, but in compensation, we should have the Full Earth in full view. Besides—and this is your chief point, no doubt, Ardan—if we should happen to be drawn round the Moon, just as we are at the present moment, we should enjoy the inestimable advantage of beholding her invisible side magnificently illuminated!"

"My idea exactly, Captain," said Ardan. "What is your opinion on this point, Barbican?"

"My opinion is as follows:" answered Barbican, gravely. "If we ever repeat this journey, we shall start precisely at the same time and under precisely the same circumstances. You forget that our only object is to reach the Moon. Now suppose we had really landed there, as we expected to do yesterday, would it not have been much more agreeable to behold the lunar continents enjoying the full light of day than to find them plunged in the dismal obscurity of night? Would not our first installation of discovery have been under circumstances decidedly extremely favorable? Your silence shows that you agree with me. As to the invisible side, once landed, we should have the power to visit it when we pleased, and therefore we could always choose whatever time would best suit our purpose. Therefore, if we wanted to land in the Moon, the period of the Full Moon was the best period to select. The period was well chosen, the time was well calculated, the force was well applied, the Projectile was well aimed, but missing our way spoiled everything."

"That's sound logic, no doubt," said Ardan; "still I can't help thinking that all for want of a little light we are losing, probably forever, a splendid opportunity of seeing the Moon's invisible side. How about the other planets, Barbican? Do you think that their inhabitants are as ignorant regarding their satellites as we are regarding ours?"

"On that subject," observed M'Nicholl, "I could venture an answer myself, though, of course, without pretending to speak dogmatically on any such open question. The satellites of the other planets, by their comparative proximity, must be much easier to study than our Moon. The Saturnians, the Uranians, the Jovians, cannot have had very serious difficulty in effecting some communication with their satellites. Jupiter's four moons, for instance, though on an average actually 2-1/2 times farther from their planet's centre than the Moon is from us, are comparatively four times nearer to him on account of his radius being eleven times greater than the Earth's. With Saturn's eight moons, the case is almost precisely similar. Their average distance is nearly three times greater than that of our Moon; but as Saturn's diameter is about 9 times greater than the Earth's, his bodyguards are really between 3 and 4 times nearer to their principal than ours is to us. As to Uranus, his first satellite, Ariel, half as far from him as our Moon is from the Earth, is comparatively, though not actually, eight times nearer."

"Therefore," said Barbican, now taking up the subject, "an experiment analogous to ours, starting from either of these three planets, would have encountered fewer difficulties. But the whole question resolves itself into this. If the Jovians and the rest have been able to quit their planets, they have probably succeeded in discovering the invisible sides of their satellites. But if they have not been able to do so, why, they're not a bit wiser than ourselves—But what's the matter with the Projectile? It's certainly shifting!"

Shifting it certainly was. While the path it described as it swung blindly through the darkness, could not be laid down by any chart for want of a starting point, Barbican and his companions soon became aware of a decided modification of its relative position with regard to the Moon's surface. Instead of its side, as heretofore, it now presented its base to the Moon's disc, and its axis had become rigidly vertical to the lunar horizon. Of this new feature in their journey, Barbican had assured himself by the most undoubted proof towards four o'clock in the morning. What was the cause? Gravity, of course. The heavier portion of the Projectile gravitated towards the Moon's centre exactly as if they were falling towards her surface.

But were they falling? Were they at last, contrary to all expectations, about to reach the goal that they had been so ardently wishing for? No! A sight-point, just discovered by M'Nicholl, very soon convinced Barbican that the Projectile was as far as ever from approaching the Moon, but was moving around it
