KIRKUS REVIEW

Ike-lay ou-yay illy-say ames-gay? If so you may enjoy trying your patience with the more advanced of these repetitious diagrammatic codes; if pig-latin is beyond your ken, however, you'll have to start at the beginning. Which is hardly worthwhile since there follow just some thirty pages of dots posited in uppers, lowers, rights, and lefts of varying geometrics--like the circle in the square or the tic-tac-toe board--to represent the positions of letters. And that's it, except for the two pages on elementary substitution-codes. It's skimpy, lazy, and unimaginative, especially in comparison to Bernice Kohn's discussion of the principles behind many sorts of Secret Codes and Ciphers. A teacher seeking new ways to convey new math might use it in desperation. . . or a bedridden child tired of coloring-books.
