mounted by a veranda, approached by a broad, handsome stairway. Both stores and offices found tenants at higher rates than tenements of similar dimensions on shore would, and returned a larger and steadier income, 'as my friend told me, than the ship would have earned if afloat."

The Niantic became part of the quickly changing scene of the San Francisco waterfront, and as the city expanded, the Niantic, like many of her neighbor vessels, found herself part of the shoreline as "waterlots are filled up with sand hills which the steam excavators remove," as noted in the Matthews papers. "This has left many of the old ships, which were a year ago beached as store-houses, in a curious position; for the filled up space that surrounds them has been built upon for some distance, and new streets run between them and the sea . . . "The Niantic was more than three blocks from the sea, and was literally "high and dry" as one resident recalled her. The entire waterfront, the business section of the city and the seat of government in San Francisco were destroyed on May 2, 1851, when fire swept the hills of San Francisco clean. Gone was the Niantic, all but her bottom burned. But that bottom made good foundations for futher building. And the buildings upon the site carried on the tradition of the Niantic; the Niantic Hotel stood on the site from 1851 to 1872, the Niantic Block from 1872 to 1906, and the Niantic Building from 1907 to 1977. Construction activities through the years encountered the remains of the Niantic, causing public comment, especially when portions of her stored merchandise, notably champagne, were uncovered. The Niantic surfaced from her earthfill grave in the heart of San Francisco's financial district in April 1978. Time and financial restriction prevented the preservation of the ship herself. Due to the concerted efforts of the developer of the project, J . Patrick Mahoney, and the San Francisco Maritime Museum, in conjunction with the National Park Service, the artifacts and the stern of the ship were saved along with an eight-foot cross section of the hull. Plans are to preserve these remnants and exhibit the hull section with the artifacts found inside it as they were uncovered, a fitting memorial and reminder of the Niantic, a modern relic of San Francisco's Gold Rush days. In her career and her transition from ship to shoreline, the Niantic was a witness and a participant in creating a new California. .ti 46

Unlike the ordinary stereo camera which produces paired images within a compact body, the two cameras employed for a photogrammetric survey might be several feet apart.
