South-Sea Bubble. This term is applied to a company instituted in 1710, and incorporated in 1716. Under cover of its legality, enormous frauds were carried on. Thousands of persons were ruined by it. The cunning of the directors had raised shares originally valued at £100, to the enormous price of £1000. The scheme exploded in 1720; when the directors' estates, to the value of £2,014,000 were seized. Mr. Knight, the cashier, absconded with £100,000, but he compounded the fraud for £10,000, and returned to England in 1743. Such was the mania at the time, that a great many wealthy persons in the kingdom became stock-jobbers and speculators in this ruinous scheme.
