Could it be 1 part water, 2 parts cement, 4 parts
Cement, sand, gravel, I believe. It would be interesting to know what strength this develops almost a century later. My father used the same "formula" when hoe-mixing concrete when I was a kid. I don't think the concept of "design strength" entered into it.
In my home town of Doylestown PA about the same time a guy named Mercer built several fairly large structures up to 5 stories with such a mix and they're still standing--with some deterioration of course--housing museums and forming a major tourist attraction.
