PaulaToo's image makes the first word a bit clearer - it looks to me like 'General'.
For a woman, 'General' is usually followed by 'servant', but I don't think this is the case here - the ending of the second word looks like '..er' (Compare with the ending of 'Labourer' on the line below).
A possibility is that the enumerator has entered John's occupation on the wrong line, and it reads 'General Labourer'. What was he doing in previous census years?
