As soon as the Space Scourge was unloaded, she was put on off-planet watch; Harkaman immediately spaced out in the Nemesis, while Trask remained behind. They began unloading the Rozinante, after setting her down at Rivington Spaceport. After that was done, her officers and crew took a holiday which lasted a month, until the Nemesis returned. Harkaman must have made quick raids on half a dozen planets. None of the cargo he brought back was spectacularly valuable, and he dismissed the whole thing as chicken-stealing, but he had lost some men and the ship showed a few fresh scars. A good deal of what was transshipped to the Rozinante was manufactured goods which would compete with merchandise produced on Gram.

"That load will be a come-down, after what the Space Scourge took back, but we didn't want to send the Rozinante back empty," he said. "One thing, I had time to do a little reading, between stops."

"The books from the Eglonsby library?"

"Yes. I learned a curious thing about Amaterasu. Do you know why that planet was so extensively colonized by the Federation, when there don't seem to be any fissionable ores? The planet produced gadolinium."

Gadolinium was essential to hyperdrive engines; the engines of a ship the size of the Nemesis required fifty pounds of it. On the Sword-Worlds, it was worth several times its weight in gold. If they still mined it, Amaterasu would repay a second visit.

When he mentioned it, Harkaman shrugged. "Why should they mine it? There's only one thing it's good for, and you can't run a spaceship on Diesel oil. I suppose the mines could be reopened, and new refineries built, but...."

"We could trade plutonium for gadolinium. They have none of their own. We could charge our own prices for it, and we wouldn't need to tell them what gadolinium sells for on the Sword-Worlds."

"We could, if we could do business with anybody there, after what we did to Eglonsby and Stolgoland. Where would we get plutonium?"
