Pollepel Island, 1950

Resting in the Hudson River, on Pollepel Island, is a crumbling hulk of intricate concrete and brickwork that was once Bannerman's Arsenal. In 1900, Francis Bannerman VI bought the island to store ammunition for his prosperous military surplus business; more specifically, when he bought 90% of the US army surplus after the Spanish-American War ended and needed a place outside of New York City to store it all. The arsenal (sometimes referred to as "Bannerman's Castle") was constructed from 1901 to 1908, and was modeled similar to the architecture of an old Scottish castle. A storm in 1950 sunk the ferryboat that served the island, Pollepel, and the arsenal was left more or less abandoned since then.

near Milwaukee, 1923

At a time in history when the Milwaukee River was a commercial corridor, fireboats were an important part of fighting urban fires. Originally named the August F. Janssen, #23 was built in Sturgeon Bay in 1896 and entered service with the Milwaukee Fire Department in 1897. Named for MFD’s Engine Company 23, which operated the vessel, the 1,000-foot-long boat served Milwaukee well, using her 4,500-gallon-per-minute water pump to extinguish fires at buildings, grain elevators, and commercial vessels along the waterfront. Historical records show that #23’s machinery and pumps were sold for junk in 1922. On July 27, 1923, she was scuttled—deliberately sunk—in Lake Michigan, a few miles from Milwaukee.
