Address includes "Croton-on-Hudson, N. Y."

Writes (verbatim — the only time Brinton wrote about the Croton property in his own voice):

"Recreation time has been, during the last year or so, largely devoted to getting into reasonable shape one hundred acres or so of Westchester County hills at Croton-on-Hudson, having one of the best views of the Hudson River and the Highlands. During 1920 my wife and I climbed Mt. Mitchell, N. C., and did some horse-backing in the Big Horn Mountains of Wyoming. We motored across eastern Oregon and hunted up a mine in California near the Mexican border."

This passage dates Brinton's acquisition of the property that would become Brinton Brook Sanctuary to circa 1920-1921 — within roughly a year of his April 17, 1920 marriage to Laura MacDonald Moses. The "one hundred acres or so" corresponds to the 112 acres Laura Brinton later donated to the National Audubon Society in 1957 as a memorial after Willard's death.
