Load cargo
I think it could be either:
'load cargo' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for stow that I've seen before include "Put away for storage" , "Keep under hatches" , "Deposit" , "Pack away cargo" , "Pack or store carefully, luggage perhaps" .)
'load cargo' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Another definition for lade that I've seen is " Take on cargo".)
