A request was received asking for the location of the Tanner dry dock. Here is a snippet view from the Cayuga Genweb 1875 map that shows where it was located.
The following map is from 1904
Compare the above to Google and you will see changes and the re-appearance of James St, but don't be fooled by the map, the street signs are labled W Dock Street at both ends (not James). You will also see slight changes to Rochester St as well.
