The Comstock King and Brownstone

“San Francisco’s crown in the matter of private architecture has rested on the brow of the city’s famous Nob Hill for the past 10 years but the brightest jewel in the setting is receiving its finishing polish,” appeared on page 4 of the May 9, 1886 New York Times.  The short article was referring to the mansion of James C. Flood, best known as one of the Nevada Comstock Kings.  His home was reportedly the most expensive private residence in America.  The reason was understandable—Flood’s 42-room estate was made of sandstone shipped around Cape Horn from Connecticut.  Total cost was $1.5 million and included a $30,000 bronze fence, which was rumored to be polished by a man whose sole job was to do so. 

Flood chose the red sandstone, better known as brownstone, because it was the stone of the wealthy.  William Vanderbilt, J.P. Morgan, and George Pullman all lived in brownstone homes, and brownstone was called an “almost proverbial synonym for all that is elegant and desirable.”  Tons and tons of brownstone was shipped as ballast around Cape Horn.  The 107 foot by 127 foot edifice featured 14 solid stone columns, 13 feet tall by 22 inches square, and 23-foot-long sandstone steps.  The biggest blocks each weighed 18 tons.

I have long wanted to see Mr. Flood’s brownstone.  Skipping out on a few sessions at AGU allowed me to reach this goal. The mansion is rather handsome and very out of place on its block surrounded by gargantuan and mostly granite buildings.  And it is clear that no one has polished the bronze fence in decades. 

The main brownstone quarries were in Portland, Connecticut.  First used for building in the 1650s, brownstone started to spread widely in the late 1700s and reached a peak by the last decade of the 19th century.  Following devastating floods, the quarries shut down around 1936, but not before the removal of 10 million cubic yards of rock. 

From a geologic point of view, brownstone has long attracted attention.  The red sands were part of an extensive series of sediments deposited in rift basins formed 200 million years ago by the separation of North America and Africa and the incipient opening of the Atlantic Ocean.  These sediments record more than 35 million years of time and stretch from South Carolina to Newfoundland.  The sediments also preserved the tracks of thousands of dinosaurs that roamed the wet sands near streams and lakes in the basins.  More than 20,000 of these tracks, including the legendary Noah’s Raven, are now displayed at the Amherst Museum of Natural History. 

James Flood’s residence was the lone mansion on Nob Hill to survive the 1906 earthquake.  It was, however, only a shell as fire had burned out the interior.  Flood had died in 1889 and his daughter sold the gutted building to the Pacific Union Club.  They hired the architectural firm run by Daniel Burnham to redesign the mansion.  Ironically, Burnham was the architect of the World’s Columbian Exposition and its White City, which contributed to white stone replacing brownstone as a favored building material.  The Flood residence is listed on the National Register of Historic Places.  Only members and their guests are allowed in the building now.
