4.--_The Knight's Puzzle._

This worthy man was, as Chaucer tells us, "a very perfect, gentle

knight," and "In many a noble army had he been: At mortal battles had he

been fifteen." His shield, as he is seen showing it to the company at the

"Tabard" in the illustration, was, in the peculiar language of the

heralds, "argent, semee of roses, gules," which means that on a white

ground red roses were scattered or strewn, as seed is sown by the hand.

When this knight was called on to propound a puzzle, he said to the

company, "This riddle a wight did ask of me when that I fought with the

lord of Palatine against the heathen in Turkey. In thy hand take a piece

of chalk and learn how many perfect squares thou canst make with one of

the eighty-seven roses at each corner thereof." The reader may find it an

interesting problem to count the number of squares that may be formed on

the shield by uniting four roses.
