Honest John says: "What I don't know about milk is scarcely
worth mentioning," but he was flabbergasted one day
when each of two ladies asked him for two quarts of milk.
One lady had a five-quart pail and the other had a
four-quart pail. John had only two ten-gallon cans, each
full of milk. How did he measure out exactly two quarts
of milk for each lady?|
It is a juggling trick pure and
simple, devoid of trick or device, but it calls for much
cleverness to get two quarts of milk into those two pails
without making use of any receptacles other than the two
pails and the two full cans.
