Beveled cuts in ceiling lath - what used to be there?
A tour of a house museum yielded a bit of a mystery that I'm hoping someone here can help figure out.
In the basement ceiling of this house, there is a beveled cut in the ceiling lath. The cut portion projects about 2 feet out from the wall and runs the length of the room (maybe 8-9 feet). No lath appears to be missing - it appears to have been cut and left in place. Why would anyone go to the trouble of making a bevel cut in each lath? What could once have been installed in that area that would necessitate beveling the ceiling lath like that?
The house was built in 1810 and the beveled lath was in a small room directly off the kitchen, possibly once used as a scullery. The room on the first floor directly above the beveled lath was probably used as a pantry. The room containing the beveled lath has had its floor replaced, so I can't tell you anything about ghosting. There might have been a sink underneath at some point, as I did see what appeared to be holes for water supply and drain pipe below it. The restorers on site felt that the space between the wall and the bevel cut was too shallow to have ever accommodated a dumbwaiter.
