Money.
“This will be found classed in the eighth set, the key to which is, ‘Look at this.’
“No. 6 of the set is described as ‘a piece of money,’ and is always of a less value than a dollar. We will take a silver quarter of the date of 1820. The question is:
“‘Look at this. What is it?’
“A. ‘A piece of money.’
“Q. ‘Let me know the amount. Will you?’
“A. ‘Twenty-five cents;’ as we know that ‘let’ is 2 and ‘will’ 5.
“If the coin is of this century, only the last two figures are asked; if of a prior date, the last three. The request therefore is:
“‘Look at the date. Hurry!’ which would bring the answer, ‘1820.’
