When we were working on the floors, we found a can lid that was nailed over the hole. It had 5 cents on the lid. No pipes or anything, so after some thought we think it was where the old fashioned washer was drained. This room is right off the kitchen, divided by a island with my stove. We like that it is really open and yet still with some modern stuff. We think the kitchen had some TLC in the 50's. But you can tell that at one time there was a wood stove. The brick chimney is still here. We have had so many mysteries about our old cottage farm house. Most of them have been salved in remodeling.
