Classic Poem

As I sunk the lobster-pots,
To myself I thought,
Luck's the cunning lobster
I have never caught.

Though I've fished for fifty year,
Man and boy, for me
Luck's the fish I've never
Drawn from the salt sea.

And good fortune, likely now,
Won't be mine to keep,
Till I go to seek it
Fifty fathom deep.
