Return to England. On the 12th of October, 1492, Christopher Columbus landed upon the shores of San Salvador, one of the West India islands, and thus revealed to astonished Europe a new world. Four years after this, in the year 1496, Sebastian Cabot discovered the continent of North America. Thirty-three years passed away of many wild adventures of European voyagers, when, in the year 1539, Ferdinand de Soto landed at Tampa Bay, in Florida, and penetrating the interior of the vast continent, discovered the Mississippi River. Twenty-six years more elapsed ere, in 1565, the first European colony was established at St. Augustine, in Florida.
