Editor’s note: This puzzle was created by Gerry Toogood who still challenges readers with his crostic puzzles today. Be warned, this 50-year old puzzle is much more difficult (in our opinion) than Gerry’s current day crostics. We’ll send a book prize to the person whose name we draw from among those who submit the correct solution to this puzzle on or before January 2, 2019. Email: kjackson@uwaterloo.ca.
