 Who is Beula and what is her connection to the narrator?
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. Beulah—that's his elephant, but I have to take care of her for him because Beulah's baby belongs to me and Beulah has to take care of it—kept us apart until we both cooled down a little. The gold-braided hat of his trade was not clamped in its usual belligerent position slightly over one eye. I only drink rhial when I've been exposed to Captain Hannah. I almost felt sorry for him, but just then Beulah came racking across the field with her two-ton infant in tow, to show her off to Hannah. 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. And by the time I had lined up for Gloryanna and Jumped, I figured, like you said, that the trip would be a cakewalk. 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. With no gravity for reference, how were the plants supposed to know that the 'sun' was supposed to be moving?" "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 for ten and one-half hours, until I had gone halfway around the room. And because somehow we had picked up half of the plants in the northern hemisphere of Mypore and the other half in the southern hemisphere, it turned out that half of the plants had a sinistral corkscrew and the other half had a dextral. It was full of minerals and manure and such, and I didn't want to introduce it into the ship's tanks."
