Adolph Sutro, The Sutro Tunnel & the Comstock Lode
Values Codes I-H-E-L-P
Adolph Sutro was born in Aachen in what we now call Westphalia, Germany, in 1830.
Adolph Sutro was educated as a engineer.
In 1850 Adolf Sutro arrived in San Francisco and was involved in merchandising tobacco, clothing and other general merchandise.
In 1859, Adolph Sutro invented a new cost effective method of refining silver ore, just at the time that the Comstock Lode was being developed in Virginia City, Nevada.
The Comstock mines were originally thought to be rich with gold. However, miners were hampered with piles of blueish slush, which had to be carted from the mines and dumped in open fields.
Eventually, someone got curious and had the slush tested. To everyone’s surprise, the blue slush was packed with silver grains. The riches of the Comstock Lode eventually turned out to be mostly silver, not gold.
Adolph Sutro started introducing himself to bankers and investors, telling about his plans for cleaning excess water and gas out of the mine shafts of the Comstock Lode.
His idea was to drive a four mile tunnel through Mt. Davidson to drain the water and gas that was hindering mining efforts, and, with tracks, to allow ore carts to roll downhill to a smelting plant at the end – that his company would own.
His company would receive a fee for each gallon of water drained and for each ton of ore removed from the many different mines that catacombed the silver rich mountain.
Adolph Sutro incorporated the Sutro Tunnel Co. and raised $3 million from investors – but needed more. A London bank came through with enough backing to allowed him to move forward.
While drilling the tunnel, Adolph Sutro led the way for many months – wielding the drill and axe at the very front of the dig – inspiring his workers behind him.
Adolph Sutro became known as the “King of the Comstock.”
When Adolph Sutro and his tunnel workers completed, four mile tunnel, it drained as much as four million gallons of water from the mines every day. This earned the Sutro Tunnel Co. an average of $10,000 a day!
Eventually, Adolph Sutro recognized that the gold and silver output of the mines was beginning to slow.
He sold his shares of the Sutro Tunnel Co. at its peak price and retired to San Francisco.
There Adolph Sutro became one of San Francisco’s greatest philanthropists.
