They cleared their lands, and earned hard cash by selling potash or "blacksalts" that they made as they burned the hardwood trees to build their farms.
The land was too rocky, the summers were too short and the winters were too cold to sustain extensive agriculture which existed only a few miles away in the St. Lawrence Valley.
What Reynoldston did have was extensive mixed forests with both hardwood and softwood, the Deer River for water power to drive saws in a lumber mill and excellent conditions for logging in the winter.
Reynoldston reached it peak from 1908 to 1918 when the Brooklyn Cooperage Company contracted the Reynolds Brothers to provide hardwood logs for making staves and barrel tops in St. Regis Falls.
The families of Reynoldston represented a cross-section of the population of Northern New York State and included French–Canadians, Irish, Scottish, from New England backgrounds.
Some to the family names were -the Allen Bordeaux, Joseph Bombard, Alfred French, Jondro, Duso, William LaHares, Nelson Duso, Joseph Meno' and Philias and Henry Moquin, Oliver Trushaw- and had very large families of 10 or more children and as such probably made up a majority of the community early in the 20th century.
Living among them at various times throughout the community's history, however, were a significant number of English, Irish, or Scottish people, - often settlers from New England – William Collins, John Cox, Henry Clark, Danford Whitcomb, Arthur Berry, Joseph Campbells, James McGovern, Patterson, Samuel Trims, and Orson L. Reynolds.
By 1925, the Reynolds Brothers had cut most of the trees on their land holding, they started the process of closing the mill and shutting down their operations.
Members of a few of the larger families, the Bordeaux's and Campbell's remained in Reynoldston to farm, make maple syrup and work as guides and the State of New York.
