evening, when the whole Bunch was in the shop.
They were around him at once, like around a hero, shouting and
questioning. There were mottled patches on his hands, and he wore dark
glasses, but he seemed at ease and happy.

"There have been some changes in the old joint, huh, Paul?" he said. "So
you guys are one of the outfits building its own gear... Looks pretty
good... Of course you can get some bulky supplies cheaper on the Moon,
because everything from Earth has to be boosted into space against a
gravity six times as great as the lunar, which raises the price like
hell. Water and oxygen, for instance. Peculiar, on the dry, almost
airless Moon. But roasting water out of lunar gypsum rock is an easy
trick. And oxygen can be derived from water by simple electrolysis."

"Hell, we know all that, Harv," Ramos laughed.

So Harv Diamond gave them the lowdown on the shortage of girls--yet--in
Serenitatis Base, on the Moon. Just the same, it was growing like corn
in July, and was already a pretty good leave-spot, if you liked to look
around. Big vegetable gardens under sealed, stellene domes. Metal
refineries, solar power plants, plastic factories and so forth, already
in operation... But there was nothing like Pallastown, on little Pallas,
out in the Asteroid Belt... Mars? That was the heebie-jeebie planet.

Gimp asked Harv how much leave he had on Earth.

"Not long, I guess," Harv laughed. "I've got to check back at the Force
Hospital in Minneapolis tomorrow..."

But right away it was evident that his thoughts had been put on the
wrong track. His easy smile faded. He gasped and looked kind of
surprised. He hung onto Paul's old swivel chair, in which he was
sitting, as if he was suddenly terribly afraid of falling. His eyes
closed tight, and there was a funny gurgle in his throat.

The Bunch surrounded him, wanting to help, but he half recovered.

"Even a good Space Force bubb, manufactured under rigid government
specifications, can tear," he said in a thick tone. "If some jerk,
horsing around with another craft, bumps you even lightly.
Compartmentation helps, but you can still be unlucky. I was
fortunate--almost buttoned into my Archer Six, already. _But did you
ever see a person slowly swell up and turn purple, with frothy bubbles
forming under the skin, while his blood boils in the Big Vacuum?_ That
was my buddy, Ed Kraft..."

Lieutenant Harvey Diamond gasped. Huge, strangling hiccups came out of
his throat. Hi
