I was browsing through the October 1930 issue of Homes and Gardens (UK) , as you would on a fine Sunday, and found an important message I must bring to your attending. It is a customer testimonial from 'A Barrister-in-law' in an advertisement (page xiv) proudly titled 'Sewage Purification'.
"... Your sewage installation has given entire satisfaction. I take every opportunity of showing and recommending it to my friends .... it would be a public benefit if your system could be adopted everywhere in lieu of cesspools."
Well done Tuke & Bell, Ltd (London).
I also found advertisements for bird baths, dog beds, stools, rugs, etc just like those around our house and available at K-Mart. Hmmm.
