One of the first fish hatcheries in the county to make use of fertilized eggs was located on the Robinson property at the turn of the 20th century. Benjamin Lincoln, resident of the Mill House and manager of Lincoln Mills, engaged James Robinson, father of William and grandfather of Raymond, to construct and operate a hatchery at the large spring brook which flows into the Dennys River. Their fertilized eggs, brought by rail from the East Orland Federal Hatchery, were hatched in hand hewn log troughs to which spring water flowed through lead pipes. The young salmon, raised in Robinson's hatchery, were released near the mouth of Venture Brook. The building that housed the hatchery was later used as an icehouse by the Robinson family.
