What is the message in the calder game?

Blue Balliett states that the eleven letters float, drift, and appear in a pattern of fives. Use the code on page 348 in "The Calder Game." Starting with chapter 1, look at every fifth illustration for the symbols to match the code. You will find the symbols in five of the illustrations. Then write the letters that correspond with the symbols. Unscramble the letters to spell the three-Word message.
