Another thing about clay – aside from being a sort of dirt that’s good for putting dead people in the ground – is that clay really can help with the smell.
If you’re burying a decomposing body, a place that helps reduce odors is a really good idea. They put clay in natural deodorant – why wouldn’t you put your smelly decaying dead guest in a clay pit? It’s a great way to reduce body odor.
