The defendant" in this case was the former owner of certain land subject to a mortgage. The mortgage was foreclosed with his knowledge. He remained in occupation of the land, and, without any contract or consent on the part of the owner, put up a house and part of a barn upon it. The female *484plaintiff then bought the land, and now seeks to enjoin the defendant from removing the structures.
When the buildings were attached to the realty, they became part of it, and the defendant does not bring himself within the rules that authorize a severance, even as against the owners at that time.
