For those of you not too familiar with New England, this is a building that was used to boil down maple sap to make maple syrup and maple sugar. It is an evaporator house, and you can see the area on the left for the storage of logs to burn under a large metal box holding the sap in the main part of the building. There is a "double roof" system that allows the steam to flow out of the building through the upper roof openings. Buckets used to be hung on the "tapped" trees to catch the running sap, and then the buckets were collected. Today modern sap,or sugar, houses are built at the bottom of a hill below where the sugar maple trees stand. Plastic tubes are put in the trees and a net work of tubes run thru the woods and gravity feed down to the sap house.
