The job was easy. The profit was enormous. The only trouble was—the cargo had a will of its own! Captain Hannah climbed painfully down from the Delta Crucis , hobbled I didn't ask Captain Hannah why he had socked me. among the stars. Call it the Look of Eagles. Captain Hannah had lost I figured that he figured that I had something to do with the way he looked. "Shipping marocca to Gloryanna III didn't turn out to be a cakewalk I only drink rhial when I've been exposed to Captain Hannah. It was anxiously, after the elephants had been admired and sent back home. The success of that venture—even if the job had turned out to be more difficult than we had expected—meant an enormous profit to both of us. The fruit of the marocca is delicious and fabulously expensive. The plant grew only on the single planet Mypore II. Transshipped seeds invariably failed to germinate, which explained its rarity. The Myporians were usually, and understandably, bitterly, opposed to letting any of the living plants get shipped off their planet. But when I offered them a sizable piece of cash plus a perpetual share of the profits for letting us take a load of marocca plants to Gloryanna III, "I got them there safely," said Captain Hannah. "And they are growing all right?" I persisted. "When I left, marocca was growing like mad," said Captain Hannah. I relaxed and leaned back in my chair. I no longer felt the need of rhial for myself. "Tell me about it," I suggested. "Your tests were no good," agreed the captain with feeling. "I'll tell I'll black your other eye," he decided. "You'll remember that I warned you that we should take some marocca out into space and solve any problems we might find before committing ourselves to hauling a full load of it?" asked Captain Hannah. "We couldn't," I protested. "The Myporians gave us a deadline. If we had gone through all of that rigamarole, we would have lost the moving?" "So what did you do?" I asked, when that had sunk in. "If the stem doesn't keep winding, the plants die and they can only take a few extra hours of night time before they run down." "Oh," said Captain Hannah in quiet tones of controlled desperation, "it was very simple. I just put enough spin on the ship to make artificial gravity, and then I strung a light and moved it every fifteen minutes The plants liked it fine. "Of course, first I had to move all the hydroponic tanks from their original positions perpendicular to the axial thrust line of the ship "Not yet," said Captain Hannah. "Like you, I figured I had the situation fairly well under control, but like you, I hadn't thought things through. The plastic membranes hadn't torn when we brought the "There were thousands and thousands of them, and each one of them made a tiny, maddening whine as it flew." around me to try to clear the nearby air a little, so that I could have room to think. The midges loved it. But the plants that were in reach died so fast that you could watch their leaves curl up and drop off. cloud—by spreading it all through the ship—or whether to try to block off the other plant room, and save it at least. So I ended up by not spray in the ship's fumigation system worked just fine. It killed the bugs without doing the plants any harm at all. Of course, the fumigation system is designed to work with the fumigator off the ship, because it's poisonous to humans too. marocca. The larvae provide an enzyme without which the plants die. "Of course. I immediately stopped slapping at the relatively few midges that had made their way into the head with me, and started to change the air in the ship to get rid of the poison. I knew it was too late "The only live midges left in the ship were the ones that had been with me during the fumigation process. I immediately tried to start a breeding ground for midges, but the midges didn't seem to want to thing they seemed to love. I didn't dare bathe, or scratch, or even wriggle, for fear of killing more of them. And they kept on itching. It was just about unbearable, but I bore it for three interminable days while the midges died one by one. It was heartbreaking—at least, it was to me. "And it was unnecessary, too. Because apparently the carolla had around, catching carolla on the wing and stuffing themselves happily. "I had to find out what was wrong with my awkward dingleburys. And that, of course, meant going out into the ship again. But I had to do on the middle line of the ship. And the unfamiliar gravity gradient, together with the Coriolis effect and all, makes the poor dingleburys dizzy, so they can't catch carolla. but I was busy. "Anyway, the action of the dingleburys triggered the violent growth phase of the marocca plants. Did you know that they plant marocca you'll recall, a mature field, which was the only kind we ever saw, is one solid mass of green growth. "The book says that it takes just six hours for a marocca field to shift from the seedling stage to the mature stage. It didn't seem that long. You could Made them forget all about me. "While they were having their orgy, I caught up on my reading. It was necessary for me to cut back the marocca vines. For one thing, I couldn't get up to the area of the bridge. For another, the main computer was completely clogged. I could use the auxiliary, on the bridge, if I could get to it, but it's a poor substitute. For another thing, I would have to cut the stuff way back if I was ever going to get the plants out of the ship. And I was a little anxious to get my Delta Crucis back to normal as soon as possible. But before cutting, I had to translate the gouge. "It turns out that it's all right to cut marocca as soon as it stops growing. To keep the plants from dying, though, you have to mulch the cuttings and then feed them back to the plants, where the roots store will poison the plants if they are fed back to them without having been "I was the special processor. That's what the instructions said—I translated very carefully—it required an 'organic processor'. "So I had to eat pounds of that horrible tasting stuff every day, and process it the hard way. reasonable at the time." Captain Hannah inhaled a sip of rhial, and had finished. "Well, go on," I urged him. "The marocca plants were still in good shape, weren't they?" Hannah nodded. "They were growing luxuriously." He nodded his head a He said, "They made me burn the entire crop right away, of course. They didn't get all of the carolla or dingleburys, though. Or spores." "Gloryanna III is the original home planet of marocca. They hated the crop. It wasn't as lucrative, but it was so much more pleasant that they outlawed marocca. Took them almost fifty years to stamp it out completely. Meanwhile, some clever native shipped a load of the stuff to Mypore II. He took his time, did it without any trouble and made his as security to pay for the cost of stamping out marocca all over again—those spores sprout fast—and for a time I was worried. "Of course, when I showed them our contract—that you alone were responsible for everything once I landed the plants safely on Gloryanna "They'll send you the bill. They don't figure it will take them more than a few months to complete the job." Captain Hannah stopped talking and stood up, painfully and a little unsteadily.
