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 Although he has never been a handsome man, he usually has the weathered and austere dignity that comes from plying the remote reaches among the stars. Call it the Look of Eagles. Captain Hannah had lost the Look of Eagles. His eyes were swollen almost shut 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 after all?" I suggested. He glared at me in silence. tell me about it?" I decided that his wince was intended for a nod, and ordered rhial. I only drink rhial when I've been exposed to Captain Hannah. It was almost a pleasure to think that I the field with her two-ton infant in tow, to show her off to Hannah. I walled off my pity. He had foisted those two maudlin mastodons off onto me in one of our earlier deals, and if I had somehow been responsible us. The fruit of the marocca is delicious and fabulously expensive. 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, they relented and, for the first time in history, gave their assent. In fact, they had seemed delighted. "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. Gloryanna III," he said balefully. "I ought to black your other eye." "Simmer down and have some more rhial," I told him. "Sure I get the credit for that. Gloryanna III is almost a twin to Mypore II. You know that marocca takes a very special kind of environment. Bright sun most "You'll remember that I warned you that we should take some marocca 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 without any trouble, even in a no-gravity condition. And by the time I had lined up for Gloryanna and Jumped, I figured, like you said, that the trip would be a cakewalk. were the plants supposed to know that the 'sun' was supposed to be "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 "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 larval stage. Instead of making cocoons for themselves, they snipped 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 doing anything, which was the right thing to do. No more plants died It was on page eleven that it mentioned casually that the midges—the correct word is carolla—are a necessary part of the life cycle of the marocca. The larvae provide an enzyme without which the plants die. "Of course. I immediately stopped slapping at the relatively few midges the adult dinglebury will eat only the adult carolla, and it has to fill itself full to bursting before it will reproduce. If I had the translation done correctly, they were supposed to dart gracefully around, catching carolla on the wing and stuffing themselves happily. together with the Coriolis effect and all, makes the poor dingleburys dizzy, so they can't catch carolla. "And if you think I figured all that out about dingleburys getting immediately got busy opening small buds on the stems of the marocca buds weren't the marocca blossoms from which the fruit formed—I'd phase of the marocca plants. Did you know that they plant marocca "The book says that it takes just six hours for a marocca field to one of the things they do is to defend the marocca against marauders. "And what's more, I found that I couldn't kill the damn things. Not if I wanted to save the plants. The growth only stops at the end of six hours, after the blossoms appear and are visited by the dingleburys. No dingleburys, no growth stoppage. turned out to be big, white, odorless flowers. They did nothing for me or to me. They drove the dingleburys wild, though, I'm happy to say. 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, "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 whatever they need against the time of the next explosive period of naturally, which takes several months. "There was one little catch, of course. The cuttings from the vines will poison the plants if they are fed back to them without having been "When I opened the airlock door, though, the spores drifting outside set the customs inspectors to sneezing and swearing more than seemed reasonable at the time." Captain Hannah inhaled a sip of rhial, and seemed to be enjoying the powerful stuff. He acted as if he thought he "Well, go on," I urged him. "The marocca plants were still in good him. 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 stuff, of course, but they liked the profit. Then, when a plague almost fortune. And got out again quickly. "The Gloryannans were going to hold my Delta Crucis 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 III, they let me go. "They'll send you the bill.
