Acres of Diamonds

There was a farmer who lived in Africa and through a visitor became tremendously excited about looking for diamonds. Diamonds were already discovered in abundance on the African continent and this farmer got so excited about the idea of millions of dollars worth of diamonds that he sold his farm to head out to the diamond line. He wandered all over the continent, as the years slipped by, constantly
searching for diamonds, wealth, which he never found. Eventually he went completely broke and threw himself into a river and drowned.
