Reports of Activity 

Reports go all the way back to the 1980's when Melville Moss was being taken care of by a nurse. Since Melville was unable to get to the 2nd floor sleeping quarters they setup a bed in the alcove of the master staircase. The nurse had a cot in the hallway going to the kitchen. One night before Melville passed away the nurse heard some sounds. Thinking that Melville may have passed she went to check. The nurse reported that Melville was fine however she did see a little girl on the landing of the master staircase. The nurse quickly returned to bed.

The apparition of a man has been seen coming down the master staircase to the main floor. The man is believed to be P.B. Moss.

Reports of a cool breeze going up and over people have been reported throughout the Mansion.
