SALT WATER FIRE SERVICE
Fresh water was at a limited supply in Brooklyn before 1917 and the arrival of Croton Water from Westchester and later Catskill water via tunnel from Manhattan. Fires however were not uncommon, and at the Brooklyn Navy Yard a separate system of Salt Water mains were installed expressly for fire-fighting.
The cover shares a design with several other remaining manhole covers at the yard, and based on the typeface used (with delicate serifs) seems to date to the late 1890's through the First World War.

This item was found on 3rd St. near Warrington. This is the only example of this particular type I have seen.
