Cumberlandite and bowenite, RI's state stones

Cumberlandite and bowenite were declared the Rhode Island state rock and mineral, respectively, by State Resolution No. 268 in 1966. I have made the interesting text of this resolution available online below. You can compare the text to its source, scans I made of the 1966 Rhode Island Acts and Resolves, further below; here's the scan as a high resolution TIFF. Michigan's state rock, Petoskey stone, is misspelled as "Petrosky stone". (Does anyone have any information about Joseph A. Thibodeau? Did he push for recognition of cumberlandite and bowenite?)
