CHAPTER XV.
GLIMPSES AT THE INVISIBLE.
In spite of the dreadful condition in which the three friends now found themselves, and the still more dreadful future that awaited them, it must be acknowledged that Ardan bravely kept up his spirits. And his companions were just as cheerful. Their philosophy was quite simple and perfectly intelligible. What they could bear, they bore without murmuring. When it became unbearable, they only complained, if complaining would do any good. Imprisoned in an iron shroud, flying through profound darkness into the infinite abysses of space, nearly a quarter million of miles distant from all human aid, freezing with the icy cold, their little stock not only of gas but of air rapidly running lower and lower, a near future of the most impenetrable obscurity looming up before them, they never once thought of wasting time in asking such useless questions as where they were going, or what fate was about to befall them. Knowing that no good could possibly result from inaction or despair, they carefully kept their wits about them, making their experiments and recording their observations as calmly and as deliberately as if they were working at home in the quiet retirement of their own cabinets.
Any other course of action, however, would have been perfectly absurd on their part, and this no one knew better than themselves. Even if desirous to act otherwise, what could they have done? As powerless over the Projectile as a baby over a locomotive, they could neither clap brakes to its movement nor switch off its direction. A sailor can turn his ship's head at pleasure; an aeronaut has little trouble, by means of his ballast and his throttle-valve, in giving a vertical movement to his balloon. But nothing of this kind could our travellers attempt. No helm, or ballast, or throttle-valve could avail them now. Nothing in the world could be done to prevent things from following their own course to the bitter end.
If these three men would permit themselves to hazard an expression at all on the subject, which they didn't, each could have done it by his own favorite motto, so admirably expressive of his individual nature. "Donnez tête baissée!" (Go it baldheaded!) showed Ardan's uncalculating impetuosity and his Celtic blood. "Fata quocunque vocant!" (To its logical consequence!) revealed Barbican's imperturbable stoicism, culture hardening rather than loosening the original British phlegm. Whilst M'Nicholl's "Screw down the valve and let her rip!" betrayed at once his unconquerable Yankee coolness and his old experiences as a Western steamboat captain.
Where were they now, at eight o'clock in the morning of the day called in America the sixth of December? Near the Moon, very certainly; near enough, in fact, for them to perceive easily in the dark the great round screen which she formed between themselves and the Projectile on one side, and the Earth, Sun, and stars on the other. But as to the exact distance at which she lay from them—they had no possible means of calculating it. The Projectile, impelled and maintained by forces inexplicable and even incomprehensible, had come within less than thirty miles from the Moon's north pole. But during those two hours of immersion in the dark shadow, had this distance been increased or diminished? There was evidently no stand-point whereby to estimate either the Projectile's direction or its velocity. Perhaps, moving rapidly away from the Moon, it would be soon out of her shadow altogether. Perhaps, on the contrary, gradually approaching her surface, it might come into contact at any moment with some sharp invisible peak of the Lunar mountains—a catastrophe sure to put a sudden end to the trip, and the travellers too.
An excited discussion on this subject soon sprang up, in which all naturally took part. Ardan's imagination as usual getting the better of his reason, he maintained very warmly that the Projectile, caught and retained by the Moon's attraction, could not help falling on her surface, just as an aerolite cannot help falling on our Earth.
"Softly, dear boy, softly," replied Barbican; "aerolites can help falling on the Earth, and the proof is, that few of them do fall—most of them don't. Therefore, even granting that we had already assumed the nature of an aerolite, it does not necessarily follow that we should fall on the Moon."
"But," objected Ardan, "if we approach only near enough, I don't see how we can help—"
