was provided and the light was first exhibited in December 1856. The protracted construction made this the last of the original eight lights to be completed, and in fact some lights in the next set were lit first. The light was situated in a sandy area towards the tip of the northern spit; the intent was for the light to serve both as a marker for the entrance and as a warning for the spit. It was immediately discovered that the low-lying site was vulnerable to the waves, and by 1867 the Lighthouse Board was already making plans to relocate the light to a new site on the south side of the entrance. In the meantime a log breakwater was placed around the light. Fog was a major problem, and a steam fog whistle was installed in 1874. The move was delayed for some decades, and in interim the light experienced numerous injuries from the elements. It was damaged by earthquakes in 1877 and 1882, subsequently leading to substantial bracing and reinforcement. High water in 1885 caused such severe damage that the house was deemed unfit for occupancy, and a temporary shelter was built to house the keeper until a replacement light could be built. The appropriation for the Table Bluff Light finally came through in 1891, and in October of the following year the lens of the Humboldt Harbor Light was moved to the new lighthouse. The lighthouse was officially closed on 31 October 1892 and the buildings were used by the
