Napanee Mills Cement Works, and The Canadian Portland Cement Co.
This is a history book of the first cement plant in Ontario that began making natural cement starting in 1867 then it became the first place to make Portland cement anywhere in North America in 1891 in Strathcona on the shores of the Napanee River in Ontario. Production later shifted to the Marlbank works by Dry Lake in 1900. It's cement was used for the big bridge across the St.Lawrence River at Quebec City, the Panama Canal, Peterborough Lift locks and more. Both sites were carefully examined, local stories and artifacts were collected and much information was found in the archives to give a good review of that important time. There are many colour photos of the site, artifacts and historic maps too. This book has 59 pages.
