carnage , thats a pretty impressive wall. Must took long time to construct. My house was built in 1862. Orignial homestead , with at the time was 113 acres. It's one of the biggest houses around here. The north wall is 60' long and 7' high , 18" thick. Just looking at that wall , makes my back hurt. Some of the rocks are huge. They all sit on a footer 24" wide X 12" deep of rocks , all round and the size of grapefruit. I would hate to figure the weight of the entire foundation.
Mine needs retuck pointed from about 3' down in some spots. The basement itself is pretty dry.
