and down a short passage which led into a sort of utility room in the midsection of the blister. One end was taken up with shelves and cases of food and other supplies, a diatherm cooker, distillation unit, mess table and the like; at the other, to the sides of the air lock, were two or three desks with books and papers. One of the desks held a periscreen which reflected the star-speckled black of space and a small bright ball which was the distant sun. A row of thick glass portholes at each end of the room let in a fair amount of light.

The thought of trying to predict the behavior of a ping-pong ball under gravity of point-o-two or thereabouts made me dizzy again.

I was on my way to Jupiter to prove once and for all that there isn't any Warp and that there are pirates on Callisto. Then I broke down a few hours out of Mars, with too much velocity to get back on the chemicals. After a while you came along, and I saw the camp, and managed to set her down. I didn't know this was your rock." "You have the craziest ideas, Tom!" "All right, let it go. I'm done with crazy ideas. The wildest one I have at the moment is to talk your uncle into thinking that I can earn my keep here and a passage back to Earth." "Good—and I'll talk him into not sending you back with the
