Here's a little history for you, something you won't find in the history books. Anyoen who has been there, knows that the cemetary is actual made up of several different cemetaries, on the same property, only divided. I don't know how much land is there among all the cemetaries, but it looks to be several hundrd acres.
Here's the historical part. The cemetary was ALL farm land, owned by Charles Tayes Russell. C.T. Russell's name sake and uncle, and then it was own by Jospeh Russell, C.T.'s father, and left to C.T. when Jospeh died. Some of the land was partitioned for the Watch Tower plot. Across the way from this plot of land NOW sits a huge Masonic temple. What was originally there was the old farm house, where a Br. Bonet lives, he was the caretaker.
The Cemetary was not owned by the Society, it was owned by a group of Bible Students, including C.T. Russell, Board of directors, etc. I haven't figured out how the Society got a hold of this property and when they sold it.
The Bible Students are the unofficial caretakers of the bethel plot.
I remember a few years ago, 1994, the Society opened the pyramid to try and retrieve the belongings they put in there back in 1919, but the thing was emptied. They left the pyramid opened. A Bible Student friend of mine drove up to restored it and seal it. Apparently the Society had no problem with desecrating a cemetary plot!
