15 март 1797 г. - Dr Joseph Browne and William Weston Propose a Way to Get Cleaner Water in New York
Описание:
They wanted to use water from the Bronx River and to use slow filtration through sand but the proposal was not approved and was later bastardized by Aaron Burr to make money and incidentally assist in the spread of cholera in New York in 1832.Добавлено на ленту времени:
