Corncrib contents (4)
I believe the answer is:
ears
'corncrib contents' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ears that I've seen before include "Spikes of corn" , "Heads of corn" , "Sear (anag.)" , "Auditory organs" , "Walls are said to have them" .)
