Homogonised? Yes, I think that's it! Thanks for that.
A mile away? You were lucky

We lived in a terraced house and there were four factories in our street. Not all of them had the sirens but the one opposite did, if I remember. It was all lit up at night as they had a night shift. Mum used to dream of a house with a view. All she could see from her bedroom window was the sign 'H Marriott and Son'

It was the sort of street where all the housewives would scrub the front steps every week and make a mysterious 'figure of eight' as they finished it.
Mum used a donkey stone and an old pair of dad's pants to do this job
