increased a shade, the pupils of his eyes disappeared under the upper lids, and his head burrowed beneath his forearms. "Oh, boy," Rose Thinker called gayly to Tin Philosopher, "this looks like the start of a real crisis session! Did you remember to bring spare batteries?" MEANWHILE, the monstrous flight of Puffyloaves, filling midwestern skies as no small fliers had since the days of the passenger pigeon, soared steadily onward. Private fliers approached the brown and glistening bread-front in curiosity and dipped back in awe. Aero-expresslines organized sightseeing flights along the flanks.
