30.--_The Puzzle of the Canon's Yeoman._

This person joined the party on the road. "'God save,' quoth he, 'this

jolly company! Fast have I ridden,' saith he, 'for your sake, Because I

would I might you overtake, To ride among this merry company.'" Of

course, he was asked to entertain the pilgrims with a puzzle, and the one

he propounded was the following. He showed them the diamond-shaped

arrangement of letters presented in the accompanying illustration, and

said, "I do call it the rat-catcher's riddle. In how many different ways

canst thou read the words, 'Was it a rat I saw?'" You may go in any

direction backwards and forwards, upwards or downwards, only the

successive letters in any reading must always adjoin one another.
