An illustrated 1940 Canadian Johns-Manville booklet on asbestos as the 'magic mineral'. It covers the mineral's legendary history, H. W. Johns's early experiments, the Jeffrey mine and town of Asbestos, Quebec, open-pit mining and milling, and J-M asbestos roofing and siding shingles, wallboards, Flexboard, Transite pipe, pipe coverings, packings, brake linings and fire suits. It says mill dust that 'hung thickly' over the town is now controlled by a Cottrell precipitator, and it describes the company's medical department, hospital and industrial hygiene engineer.
