1761  (1965)   Happy Laurentia, to thy farthest shore, Lavish of life, a chosen band she led; And to those royal towers her standard bore, Whence fell Oppression, Gallic tyrant fled.
1889  Laurentia! Superb Laurentia! / Thy mountains in the garment of the cloud. . . .
1963  Because so much of the story deals with trips here and there around Laurentia and Acadia, the need for a guide should have been obvious.
