Abstract

The article focuses on the invention of a dredging machine called the "Hippopotamus," created by Arthur Donaldson in 1773 for deepening harbors and water passages. The machine, which operated using a horse and three workers, was capable of moving sixty to eighty tons of mud and gravel daily. The American Philosophical Society (APS) documented Donaldson's invention, encouraging its presentation to the Pennsylvania Assembly for funding, which ultimately awarded him a monetary reward for his ingenuity. The article also highlights the recent conservation efforts made on the original drawing of the machine. [Extracted from the article]
