Crows.

They stream across the fading western sky
A sable cloud, far o'er the lonely leas;
Now parting into scattered companies,
Now closing up the broken ranks, still high
And higher yet they mount, while, carelessly,
Trail slow behind, athwart the moving trees
A lingering few, 'round whom the evening breeze
Plays with sad whispered murmurs as they fly.
  
A lonely figure, ghostly in the dim
And darkening twilight, lingers in the shade
Of bending willows: "Surely God has laid
His curse on me," he moans, "my strength of limb
And old heart-courage fail me, and I flee
Bowed with fell terror at this augury."
