Lake, particularly near Naples, have for many years been utilized 

 for the production of grapes. Hop growing, which was of some 

 prominence during the latter half of the last century, is no

 Bristol Center. Cabbage is largely raised, and, according to the 

 census of 1918, Ontario County leads in its production.
