Thumping sounds gone

The thumping sound that was so regular in the Library and later was loud and irregular in the kitchen has not been heard since July 15th in the Kitchen and for a good bit longer than that in the Library. Its the kind of noise that can drive you nuts because you want to know what is causing it. The sound had been quiet at other times for short periods of time only to begin again. So it will be interesting to find out if this period of silence will continue or not and whether or not the sound will begin again in some other room of the house.
