"Legs and ankles," said Snorky instantly.

"Bright boy—you're getting closer."

"That—that's my sock."

"You call 'em hole-proof socks," said Skippy, ignoring the aspersion. "You get it? You don't? Suppose we change it, suppose we use the same organization but call it—Mosquito-Proof Socks."

"Mosquito-Proof Socks!" said Snorky in a whisper.
