Flannan Isle

But, as we neared the lonely Isle;
And looked up at the naked height;
And saw the lighthouse towering white,
With blinded lantern, that all night
Had never shot a spark
Of comfort through the dark,
So ghostly in the cold sunlight
It seemed, that we were struck the while
With wonder all too dread for words.
And, as into the tiny creek
We stole beneath the hanging crag,
We saw three queer, black, ugly birds—
Too big, by far, in my belief,
For guillemot or shag—
Like seamen sitting bolt-upright
Upon a half-tide reef:
But, as we neared, they plunged from sight,
Without a sound, or spurt of white.
