[Transcriber's Note: This etext was produced from Worlds of Tomorrow June 1963 Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Captain Hannah climbed painfully down from the Delta Crucis , hobbled across the spaceport to where Beulah and I were waiting to greet him and hit me in the eye. 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. The gold-braided hat of his trade was not clamped in its usual belligerent position slightly over one eye. He had foisted those two maudlin mastodons off onto me in one of our earlier deals, and if I had somehow been responsible for his present troubles, it was no more than he deserved. 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, they relented and, for the first time in history, gave their assent. Bright sun most of the time—that means an almost cloudless environment. Days and nights the same length and no seasons—that means no ecliptical and no axial tilt. If we had gone through all of that rigamarole, we would have lost the franchise. I almost asked him why he had been barricaded in the bathroom of the Delta Crucis , but I figured it was safer to let him tell me in his own way, in his own time. The plastic film kept the water in the hydroponic tanks 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. So the stem looks like a corkscrew?" I nodded. In Limbo, moving at multiple light-speeds, the whole Universe, of course, turns into a bright glowing spot in our direction of motion, with everything else dark. So I lined up the Delta Crucis perpendicular to her direction of motion, put a once-every-twenty-one hour spin on her to match the rotation rates of Mypore II and Gloryanna III, and uncovered the view ports to let in the light. It gradually brightened until 'noon time', with the ports pointing straight at the light source, and then dimmed until we had ten and one-half hours of darkness.
 Irony: Captain Hannah faces so many trials and tribulations during his time with the plants that his voyage is very much NOT a cakewalk to Gloryanna.
 Metonymy: “Cake Walk” is a literal attribute/adjunct for the part of the ship Captain Hannah grows the marocca in.  Irony: Captain Hannah faces so many trials and tribulations during his time with the plants that his voyage is very much NOT a cakewalk to Gloryanna.  Metaphor: Cake walk is a metaphor the narrator uses to describe Captain Hannah’s journey once complete. They were both surprised at the venture’s absurd ease.  Euphemism: “Cake walk” is used by the narrator to politely suggest that the plants had their way with Captain Hannah.
