Is Ben's “Frugal Thought” Correct….
In an Acre of Land are 43560 square feet,
In 100 Acres are 4356000 square feet;
Twenty Pounds will buy 100 Acres of the Proprietor.
In 20 lb. are 4800 pence; by which divide the Number
Of feet in 100 Acres; and you will find that one penny
Will buy 907 square Feet; or Lot of 30 Feet square.
Save Your Pence!
