7. How Granitoid Was Made
From Patent No. 856,105, issued June 4, 1907:
"Be it known that we, William J. Sinek and Rudolph S. Blome, citizens of the United States, residing at Chicago, have invented certain new and useful improvements in Pavements and Methods of Making the Same..."
Step 1: Roadway excavated.
Step 2: Macadam foundation laid - crushed rock, cinders, or gravel, compressed to form a smooth, hard surface.
Step 3: Concrete gutter/curb poured.
Step 4: Five-inch-thick base course of concrete laid.
Step 5: Wearing surface added - a composition of cement and crushed granite. In Duluth, a hard black stone called gabbro, found locally, was used, instead of Granite.
"Before the facing has hardened, it is grooved or scored to provide footholds for the horses' shoes... We also brush it crosswise with a bristle brush to slightly scratch its surface so that it will not be too smooth or slippery."

8. Paving the Way
[newspaper article, council minutes, paving contract]
In 1908 a group of Duluth residents, eager to improve streets in their Chester Park neighborhood, petitioned the city for granitoid pavement. Over the next three years the patented material was laid on several streets. At the same time the city made other improvements, installing sidewalks and creating the small park where you now stand.
The granitoid streets served Duluth for more than 90 years. When deterioration set in, local preservationists worked to keep two blocks of the historic paving in place on Seventh Street. Other fragments were salvaged and installed here in 2004.
