Uller Uprising | Page 7

leaving a series of smoke-rings to float more slowly after it. That fireball flattened, then spread to form the mushroom-head of a column of incandescent gas that mounted to overtake it, engorging the smoke-rings as it rose, twisting, writhing, changing shape, turning to dark smoke in one moment and belching flame and crackling with lightning the next. The armor-tender began to pitch and roll; it was all the engineer and one of the assistants could do, together, to keep it level.
"In about half an hour," the large young man told the girl, "the real fireworks should be starting. What's coming up now is just small debris from the nuclear blast. When the shockwaves get down far enough to crack things open, the gas'll come up, and then steam and ash, and then the magma. This one ought to be twice as good as the one we shot three months ago; it ought to be every bit as good as Krakatoa, on Terra, in 59 Pre-Atomic."
"Well, even this much was worth staying over for," the girl said, watching the screen.
"You going on to Uller on the City of Canberra?" Louren?o Gomes asked. "I wish I were; I have to stay over and make another shot, in a month or so, and I've had about all of Niflheim I can take, now. The sooner I get onto a planet where they don't ration the air, the better I'll like it."
"Well, what do you know!" the large young man with the hairy legs mock-marveled. "He doesn't like our nice planet!"
"Nice planet!" Gomes muttered something. "They call Terra God's Footstool; well, I'll give you one guess who uses this thing to prop his cloven hoofs on."
"When are you going to Terra?" the girl asked him.
"Terra? I don't know, a year, two years. But I'm going to Uller on the next ship--the City of Pretoria--if we get the next blast off in time. They want me to design some improvements on a couple of power-reactors, so I'll probably see you when I get there."
"Here she comes!" the chief engineer called. "Watch the base of the column!"
The pillar of fiery smoke and dust, still boiling up from where the bombs had gone off far underground, was being violently agitated at the bottom. A series of new flashes broke out, lifting and spreading the incandescent radioactive gasses, and then a great gush of flame rose. A column of pure hydrogen must have rushed up into the vacuum created by the explosion; the next blast of flame, in a lateral sheet, came at nearly ten thousand feet above the ground, and great rags of fire, changing from red to violet and back through the spectrum to red again, went soaring away to dissipate in the upper atmosphere. Then geysers of hot ash and molten rock spouted upward; some of the white-hot debris landed almost at the acid river, half-way to the armor-tender.
"We've started a first-class earthquake, too," the Hispano-Indian Martian Murillo said, looking at the instruments. "About six big cracks opening in the rock-structure. You know, when this quiets down and cools off, we'll have more ore on the surface than we can handle in ten years, and more than we could have mined by ordinary means in fifty."
About four miles from the original blast, another eruption began with a terrific gas-explosion.
"Well, that finishes our work," the large young man said, going to a kitbag in the corner of the cabin and getting out a bottle. "Get some of those plastic cups, over there, somebody; this one calls for a drink."
"That's right," Gomes said. "You do something once, it may be an accident; you repeat the performance, and it's a success." He began pushing papers aside on his desk, and the girl in the too-ample coveralls brought drinking cups.
The Ulleran, in the background, rose quickly and squeaked apologetically. Murillo nodded. "Yes, of course, Gorkrink. No need for you to stay here." The Ulleran went out, closing the door behind him.
"That taboo against Ullerans and Terrans watching each other eat and drink," Murillo said. "What is that, part of their religion?"
"No, it's their version of modesty," the girl replied. "Like some of our sex-inhibitions, which they can't even begin to understand.... But you were speaking to him in Lingua Terra; I didn't know any of them understood it."
"Gorkrink does," Murillo said, uncorking the bottle and pouring into the plastic cups. "None of them can speak it, of course, because of the structure of their vocal organs, any more than we can speak their languages without artificial aids. But I can talk to him in Lingua Terra without having to put one of those damn gags in my mouth, and he can pass my instructions on to the others. He's been a big help; I'll be sorry to lose him."
"Lose
