So I can read Millwright, the part in brackets has been transcribed as Grouse Maker, and comparing to the line below with the House of House Wife I can see why (I am not sure that sentence is grammatical, but I hope you know what I am trying to say). But what does it say really? This is Fred Mays (b. 1861 Cirencester) in Watford (actually it's more like 1857 on other censuses if anyone wants to look for him) he's been a miller and a miller's stoneman also
FMP have it transcribed as 'granosemaker' - and rootling around I've found that "Granose was the world’s first flaked cereal product" see the article about The Battle of the Cornflakes at Code: https://www.historytoday.com/archive/battle-cornflakes
Granose Foods Ltd used to be in Stanborough Park, North Watford, but this was much later and was part of the health food industry. I think it was owned by the Seventh Day Adventist Church - who also owned Stanborough park. Edited to add that I have now discovered that the factory opened in 1900, so could well be where your chap worked. One article reads: (1938) DURING the thirty-eight years of our existence quite a number of products have been added until we now have about forty-six. These can be grouped into the following departments : Cereals; Starch Re- duced Foods; Nut Foods; Remedial Foods.
Perfect, it does actually say that he worked for a "Health Food Manufacturer", I was surprised to see the term used in 1911
There is a Facebook page called “Adventist Memorabilia” with lots of info and there is a related website on there although I haven’t accessed it, so don’t know what’s there.
