How Frequently Does the Fog Horn Blow?

This former foghorn building served as quarters for the 3rd Assistant Keeper.

When the cannon proved ineffectual after four years, it was replaced by a fog bell. And In 1874, a steam siren fog signal was installed here. During heavy fog, the horn will blow a 5-second blast every 35 seconds.
In 1910, the fog horn building was converted to the keeper's residence after his home, atop the hill, was destroyed in the 1906 earthquake. At his new wind whipped residence, the 3rd Assistant Keeper, Alexander Martin, had a small yard outside. He fashioned a harness and tether so the kids could play safely. The story goes that one day his wife stepped outside and found her small daughter dangling over the cliff's side, swinging on her tether, and that was the end of it. Tradition has it that the house was never used by the family again, and it became known as the Bachelor's House.
