1.--_The Reve's Puzzle._

[Illustration]

The Reve was a wily man and something of a scholar. As Chaucer tells us,

"There was no auditor could of him win," and "there could no man bring

him in arrear." The poet also noticed that "ever he rode the hindermost

of the route." This he did that he might the better, without

interruption, work out the fanciful problems and ideas that passed

through his active brain. When the pilgrims were stopping at a wayside

tavern, a number of cheeses of varying sizes caught his alert eye; and

calling for four stools, he told the company that he would show them a

puzzle of his own that would keep them amused during their rest. He then

placed eight cheeses of graduating sizes on one of the end stools, the

smallest cheese being at the top, as clearly shown in the illustration.

"This is a riddle," quoth he, "that I did once set before my fellow

townsmen at Baldeswell, that is in Norfolk, and, by Saint Joce, there

was no man among them that could rede it aright. And yet it is withal

full easy, for all that I do desire is that, by the moving of one cheese

at a time from one stool unto another, ye shall remove all the cheeses to

the stool at the other end without ever putting any cheese on one that is

smaller than itself. To him that will perform this feat in the least

number of moves that be possible will I give a draught of the best that

our good host can provide." To solve this puzzle in the fewest possible

moves, first with 8, then with 10, and afterwards with 21 cheeses, is an

interesting recreation.
