"Poppycock!" the general roared. "Yes, sir," said Whitlow, somewhat cowed. "Muscle-building. That's the secret. Endurance. Stress. Strain. Tension." "If— If you say so ..." said Whitlow, slumping lower and lower in his chair as the general's massive form leaned precariously over him. "But—" "Of course you are puzzled," said the general, suddenly chummy. "Anyone would be. Until they realized the use to which I've put the Whirligig!" "Yes.
