Can anyone decipher this occupation from the 1851 census? The first part is 'Wife of do. &' (do. being Labourer and Thatcher) but I cannot work out the second part. I think it is something like 'Dame's School' but this doesn't make sense.

The entry is for Mary Fagg, wife of William Fagg on HO107/1632, folio 784, page 16, second line on the page.
