Narrative:

After approximately a forty five minute flight; I began to setup for a two mile landing approach at my departure airport. At about 1;700 ft the engine stuttered then stopped. I began emergency landing procedures; setup best glide attitude; picked best emergency landing field; tried to start the engine three times and declared an emergency--although my altitude was too low for unicom to hear me; so I idented the transponder (not enough time to squawk emergency code). A local pilot heard my mayday and relayed it to the airport.I completed a normal off airport landing in a cornfield. No injuries! No apparent damage to the aircraft. Contacted tower via phone and informed them of the situation. Tower was most helpful and offered assistance. I advised no further assistance was needed. An inspection discovered a blockage existed in the fuel vent line this is not an item on the preflight check list. I would strongly suggest that a cover used on this vent hose and blowing into hose as part of preflight.
