THE CANTERBURY PUZZLES
engaged so many weeks in trying to find a solution to the problem,

The Eight Clowns.
This illustration represents a troupe of clowns I once saw on the
Continent. Each clown bore one of the numbers 1 to 9 on his
body. After going through
the usual tumbling, juggling,

one of which was the rapid
formation of a number of
magic squares. It occurred
to me that if clown No. 1
failed to appear (as happens

how these eight clowns may
arrange themselves in the
form of a square (one place
being vacant), so that every
one of the three columns, three rows, and each of the two diagonals
shall add up the same. The vacant place may be at any part of
the square, but it is No. 1 that must be absent.
