... Report on the building and ornamental stones of Canada, vol. I-V
A five-volume government survey of Canadian building and ornamental stone, written by geologist W. A. Parks for the Mines Branch and printed in Ottawa in 1912 for quarry operators, architects and builders. Halftone photographs show bedded rock faces and slide-covered slopes with men for scale, cut masonry walls and window details, alongside line-engraved district maps with hatched geological legends.
