2 They were farre past the passage, which he spake,
And come vnto an Island, waste and voyd,
4 That floted in the midst of that great lake,

6 And that gay paire issuing on the shore
Disburdned her. Their way they forward take
8 Into the land, that lay them faire before,
Whose pleasaunce she him shew'd, and plentifull great store.
