A Tragedy

Who's that walking on the moorland?
Who's that moving on the hill?
They are passing 'mid the bracken,
But the shadows grow and blacken
And I cannot see them clearly on the hill.
  
Who's that calling on the moorland?
Who's that crying on the hill?
Was it bird or was it human,
Was it child, or man, or woman,
Who was calling so sadly on the hill?
  
Who's that running on the moorland?
Who's that flying on the hill?
He is there--and there again,
But you cannot see him plain,
For the shadow lies so darkly on the hill.
  
What's that lying in the heather?
What's that lurking on the hill?
My horse will go no nearer,
And I cannot see it clearer,
But there's something that is lying on the hill.
