'hewn tree in glencoe with iodine' is the definition.
I can't judge whether this defines the answer.

'on the stump?' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'the stump?' becomes 'construction' (stump is a kind of construction).
're'+'construction'='RECONSTRUCTION'

Can you help me to learn more?
