"This cross-number puzzle was given to me by a secretary at the bank where I formerly was employed. I don't know where she got itbut it is obviously English and around thirty years old. It is a marvelous problem. Solving it requires a well-balanced combination of logic, calculation, and trial-and-error. The numbers are so interlocked that practically every one of them must be employed in reaching the final entry (2 down)." "The puzzle concerns a farm that has been in the Dunk family for some years. A part of the farm is a rectangualr piece of ground known as Dog's Mead. Additional background information: The year is 1939; 2820 quare yards = one acre; 4 roods = one acre." 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
