“For heaven's sake," panted Archimedes, bobbing in the dark air beside him, "stop flying like a woodpecker. Anybody would take you for a Little Owl, if the creatures had been imported. What you are doing is to give yourself flying speed with one flick of your wings. You then rise on that flick until you have lost flying speed and begin to stall. Then you give another just as you are beginning to drop out of the air, and do a switch-back. It is confusing to keep up with you.”
