1896 Building & Ornamental Stones, 1901 Clays & Clay Industries of Wisconsin, antique books Wisconsin regional products

Lot of two rare books published at the turn of the century by the State of Wisconsin. Clays and Clay Industries of Wisconsin is dated 1901. Buildings and Ornamental Stones is dated 1896.

These have so much material specific to regions and their products, mainly with an eye to the geology of Wisconsin and its products as building materials. I found so much I wanted to show from these books, so interesting! Both books are in good used condition.
