Found this in an aromatic hardback with a faded spine...
'Climbing Suilven' by Norman MacCaig
I nod and nod to my own shadow and thrust
A mountain down and down.
Between my feet a loch shines in the brown,
Its silver paper crinkled and edged with rust.
My lungs say, No;
But down and down this treadmill hill must go.
Parishes dwindle. But my parish is
This stone, that tuft, this stone
And the cramped quarters of my flesh and bone.
I claw that tall horizon down to this;
My shadow jumps huge miles away from me.
