"One of the older buildings of the yard was a large three-story structure with granite walls, which had become obsolete, and unsuitable for modern shop purposes. This building was entirely reconstructed by removing the second- and third-floor structures and reducing the height by one story, as shown in figure J-7. The excess granite was reused in constructing a large addition one one side."[1,p.85]
