Dan: "I must go down to the sea again, to the lonely sea and the sky. To the flung spume and the blown spray and the... I don't know, the thing in my eye."
Actually, this is two nonsequential lines from a poem titled, Sea Fever, by British poet John Masefield.
The completed first line is perhaps more recognizable:
I must go down to the sea again, to the lonely sea and the sky; and all I ask is a tall ship and a star to steer her by
and the second line is:
And the flung spray and the blown spume, and the sea-gulls crying.
