Oak droppings (6)
I believe the answer is:
acorns
'oak droppings' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for acorns that I've seen before include "'From little . . . . . . mighty oaks do grow'" , "'Great oaks from little ...... grow'" , "Fruits of the oak tree" , "nuts" , "Seeds of the oak" .)
