Morris Canal In 1831, Douglass submitted his resignation to the academy and it was accepted, as his outside projects were becoming more of a distraction. First and foremost was as a consulting engineer for the
Morris Canal, in particular as the designer of the Montville
inclined plane. As the Newark
Eagle reported, the 1830 test of the device was a major success: The machinery was set in motion under the direction of Major Douglass, the enterprising Engineer. The boat, with two hundred persons on board, rose majestically out of the water; in one minute it was upon the summit, which it passed apparently with all the ease that a ship would cross a wave of the sea. As the forward wheels of the car commenced their descent, the boat seemed gently to bow to the spectators and the town below, then glided quickly down the wooden way. In six minutes and thirty seconds it descended from the summit and re-entered the canal, thus passing a plane one thousand and forty feet long, with a descent of seventy feet, in six and one half minutes. These inclined planes became an internationally renowned tourist attraction. The
Elbląg Canal, one of
Seven Wonders of Poland, used the Morris Canal's technology as inspiration for its inclined planes; for that reason, the inclined planes on that canal strongly resemble those on the Morris canal.
Green-Wood Cemetery One of the Douglass's most significant lasting legacies is
Green-Wood Cemetery in New York. It established a style of peaceful, natural setting known as a
rural cemetery that was copied several times by Douglass himself as well as his admirers.
President of Kenyon College Douglass was the third president of
Kenyon College, serving from 1841 to 1845. He wrote two monographs concerning the reasons for his departure.
Other post-military projects Other noteworthy projects that Douglass led or was a major contributor in included surveying the
Brooklyn and Jamaica Railroad route, the design of a major water delivery system for New York City, and the design of two garden cemeteries based on his design of Green-Wood:
Albany Rural Cemetery in
Menands, New York (1845–1846), and
Mount Hermon Cemetery (1848), located on the outskirts of
Quebec City. Douglass was also originally awarded the design of the
High Bridge of the
Croton Aqueduct system, but was later fired.
Final years In October 1848, Douglass was appointed Professor of Mathematics at
Hobart College, then known as Geneva College. In October 1849, he died of a stroke. ==See also==
