Carry, convey (4)
I believe the answer is:
tote
I believe this is a double definition.
'carry' is the first definition.
(toting is a kind of carrying)
'convey' is the second definition.
(I've seen this in another clue)
(Other definitions for tote that I've seen before include "Horse race betting system" , "transport" , "It takes bets for horse races" , "Form of betting: carry" , "system that could be for the better" .)
