To split hairs on this one , I think it actually says Tobaca, not Tobacco. Same thing, at the end of the day... And for no reason other than quenching my curiosity , what is the middle word in the "Unpaid ... Duties" entries? (Nothing to do with your Henry, I know, but I am curious. )
As for the Unpaid .. Duties, it's dom short for domestic. Usually entered as UDD per the instructions to the enumerators.
Henry in 1911 census was a Tobacco Cutter.John
