“ [Artemis] returned to the aft bay for Mulch's version of a briefing. The dwarf had drawn a crude diagram on a backlit wall panel. In fairness, there were more artistic chimpanzees. And less pungent ones. Mulch was using a carrot as a pointer, or more accurately, several carrots. Dwarfs liked carrots. 'This is Koboi Labs,' He mumbled around a mouthful of vegetable. 'That?' exclaimed Root. 'I realize, Julius, that it is not an accurate schematic.'The Commander exploded from his chair. 'An accurate schematic? It's a rectangle for heaven's sake!'Mulch was unperturbed. 'That's not important. This is the important bit.' 'That wobbly line?' 'It's a fissure,' pouted the dwarf. 'Anybody can see that.''Anybody in kindergarten maybe. So it's a fissure, so what?''This is the clever bit. Y'see that fissure is not usually there.'Root began strangling the air again. Something he was doing more and more lately. ”
