TO THE EDITOR OF THE GREAT ROUND WORLD:

In your edition of Jan. 21st, 1897, you wrote of the swallowing
up by the sea of Robinson Crusoe's Island, or the island of Juan
Fernandez. Now I have always heard this island called "Robinson
Crusoe's Island," and I think the reason is, that Alexander
Selkirk was cast away there, and on his adventures the story of
Robinson Crusoe was written by Daniel Defoe. But I have read
"Robinson Crusoe," and the island as described by him cannot be
the Island of Juan Fernandez, but must be one of the Windward
Islands in the Caribbean Sea, off the mouth of the great Orinoco
River in South America, and I think is the Island of Tobago;
this best fits the careful description of Daniel Defoe.

In Crusoe's first exploration of the island he says:

"I came in view of the sea to the west, and it being a very
clear day, I fairly descried land,... extending from the W. to
the W.S.W.... It could not be less than fifteen or twenty
leagues off."
