Google Books tells me that these words appear in Songs of Phi Delta Theta ([USA]: The Fraternity, 1922), page 323:

"... of the night,
We shall see the shores of Scotland at the dawning of the light...."

From what I know of copyright law, this book should be in the public domain (if 1922 is the correct date), but Google hasn't made the images viewable. I don't know why.

Google doesn't find those exact words anywhere else.
