State name, number after one is hauled up (5)
I believe the answer is:
niger
'state' is the definition.
(Niger is an example)
'name number after one is hauled up' is the wordplay.
'name' becomes 'reg' (Reg is a man's name).
'number' becomes 'n' (n can represent any number).
'after' means one lot of letters go next to another.
'one' becomes 'i' (Roman numeral).
'is hauled up' is a reversal indicator (in a down clue, letters go up).
'n' put after 'i' is 'in'.
'reg'+'in'='regin'
'regin' backwards is 'NIGER'.
(Other definitions for niger that I've seen before include "22 across (anag) -- northwest African river" , "African state and river" , "West African country, capital Niamey" , "one flowing through Mali" , "River, Africa's largest delta" .)
