Here stood the Round House used by the Orange Mills Company in the 1800s. It was used to store the saltpeter and sulfur before it was distributed from mill to mill. The charcoal was also stored here. The Round House was located across the street from the main building on the mill property and is connected to the underground water passage. This water passage was used to move the products from mill to mill.

Here stood the charge house used by the Orange Mills Company. The Charge House was powered from the water flowing through all three ponds. It used this power to run the machines and belts used to carry, compress and crush the saltpeter and sulfur.

Here stood the Press Building, 1851-1901. The wheel cakes were taken to the press building where it was compressed to insure the ingredients did not separate while being transported or processed. The Two inch wheel cake was placed on a copper plate, two feet square and then wrapped in canvas. Acting like a cider press, the press made the wheel cake into a slate-like slab, one inch thick.

1916 -- Mrs. Annie Delano Hitch donated land to the City for a "Driving Park"; later known as Delano-Hitch Recreation Park.  The City of Newburgh Lions Club signed its charter to become formal service club on December 18, 1923. Anne Delano Hitch was the first woman to be a member of Lions International in 1924. We owe Delano-Hitch Park to her insight and philanthropy. We also owe Algonquin Park in the township to Lion member Frederic Delano Hitch. (Source:

The "Driving Park was known as Recreation Park. Thnere was ample room for roadsters to drive their car around and then picnic in the fields.  In 1911 the area was the site of the first "lighter than air craft" landing by aviationist Lincoln Beachey.  In 1931 a swimming pool was constructed. (And restored in 2000.)  (Source:  Kevin Barrett. 2000. Images of America: Newburgh. Charleston, SC: Arcadia Press.)

Frederic Delano Hitch was born in 1833 in Fairhaven, Massachusetts.  In 1860 he went to China and entered the service of Russell and Company, leading merchants and bankers.  In 1877 he married Annie Lyman Delano (1849-1926), whose parents were Warren and Catherine Delano of "Algonac," New York.  He remained in China until 1884 when he retired.  He took up residence in "Algonac," Newburgh, New York.  He and his wife were aunt and uncle of President Franklin D. Roosevelt.  They were actively involved in various phases of social work in the area.  He died in 1911.  (


Three ponds, a stream, small woods, lawns.


Baseball fields; picnic areas and a children's playground.  Around the ponds they have a real problem with way too many Canada geese.  They have a sign saying not to feed the ducks, but when we were there, people were feeding the geese.
