From small height, here perhaps drop bundles (7)
I believe the answer is:
sheaves
'bundles' is the definition.
(I know this)
'from small height here perhaps drop' is the wordplay.
'from' becomes 's' (I can't justify this - if you can you should give a lot more credence to this answer).
'small height' becomes 'h' (abbreviation in geometry; 'small' suggests an abbreviation).
'here perhaps drop' becomes 'eaves' (as in eavesdropping).
's'+'h'+'eaves'='SHEAVES'
(Other definitions for sheaves that I've seen before include "Bundles of grain stalks" , "loads of paper" , "He saves (anag.)" , "Bundles of corn tied together" .)
