How does Bailey Fountain elucidate its Dome fountain?
The 1873 dome fountain by Calvert Vaux replaced the 1867 fountain with a two-tiered, double-domed structure of cast iron and molded sections of Beton Coignet. Gaslights in the 37.2 foot (11.4 m) diameter dome were visible through one of 24 colored glass windows for evening illumination. Additional gaslights mounted in the guardrail illuminated the surface of the pool.  The Brooklyn Mayor criticized the water use of the fountain which could pump 60,000 gallons an hour, and by the 1890s the fountain leaked and was frequently dry. A boy drowned in the fountain in June 1895.
