mr. isham sold the property in 1934 to robert c. roebling (great-grandson of john augustus roebling). the roebling family (robert, dorothy, and five children) established a farm for black angus cattle while living on their schooner, the "black douglas", which provided all of the power needed by the farm until it was sold in 1941 to the united states fish and wildlife service. the cattle farm was very successful for the next twenty years, until it came to an end in 1954 due to post-wwii economic pressures. many of the buildings from the farm are still standing and in use by skio, most notably the seven-sided barn with its compass rose mosaic at the center.
