The cracker style house built in 1910 that Laura (Riding) Jackson and Schuyler B. Jackson bought in 1940 in Wabasso, Florida, where the pair worked on their new dictionary in which words would have only one meaning. Their work supported by selling citrus from their 11-acres of groves surrounding the house to northern markets. Schuyler died in 1968 and Laura took until her death in 1991 to complete their shared literary effort, which was published in 1997 under the title, Rational Meaning: A New Foundation for the Definition of Words and Supplementary Essays. The house was moved in 1994 a mile east to an island in the Indian River Lagoon where it now sits on the grounds of the Environmental Learning Center.
