EDITING SAM LOYD
Dover Publications asked me to prepare a new edition of Sam Loyd's Cyclopedia. This took much longer than anticipated because of there are many more omissions and error than anticipated. Here are a number of problems for which I cannot find a solution. Comments or solutions gratefully accepted.

In Sam Loyd's Cyclopedia, pp. 245 & 372, his 'The Three Napkins' puzzle considers three square napkins, each one foot square. He asks what is the largest square these three can cover. His answer that they will cover a 15 1/4 inch square. He places one napkin at the corner of the large square and then says 'the others will easily cover the remainder'. Making a model, one does find that they do indeed easily cover the remainder. Below, I will insert a drawing showing how the second napkin fits over the first. Loyd gives no analysis, but it seems there is some extra space and so one asks: what is the largest square that three equal squares can cover??

On p. 292, Loyd asks for the shortest game of checkers (= draughts). The shortest game with no captures takes 24 moves and this has been proven. But in 1978, a game of only 20 moves was found – White captures all the Black men. As of 1997, it was not known if this was the shortest game.

Loyd asserts HANNAH can be spelled 14,400 different ways!!

Loyd's answer is “In Puzzleland, the king tells us that as written, the owl's wise remark can be read ten different ways.”

Neither Loyd nor Gardner gives a solution. Here is a solution of mine.
Weigh a bag of 9. Weigh 5 from it, leaving 4 in the bag. Using the scales, divide this in two equal amounts, which allows us to weight the rest into 2lb bags.
