O Young Mariner You From The Haven

O young mariner, you from the haven
Under the sea-cliff, you who are watching
Broader and brighter the Gleam flying onward,
So to the land’s last limit I came,
There on the border of boundless ocean,
And all but in heaven, hovers the Gleam.

Not of the sunlight, not of the moonlight,
Not of the starlight, O young mariner,
Down to the haven call your companions,
Launch your vessel, and crowd your canvas,
And, ere it vanishes over the margin,
After it, follow it, follow the Gleam.
