cedar, black locust, redwood and others have that quality. I read some info on it in the U.S. Dept. of Ag. Wood Handbook, but it didn't explain it or clarify.

Some trees contain oils that contain substances such as terpines which resist biological breakdown and can act as a preservative. Other woods my be very dense and resist penetration by water and thus retarding microbial activity and rot as well as carrying resistant oils. Woods that carry a heavy scent usualy indicate a higher natural oil content and a better chance of preservation.

Well, you already pointed out the first thing I was going to say: Autumn did get Schroedinger's Cat experiment wrong. And for a second thing: opening the box and viewing what happens does affect the outcome in a way, but based on his experiment, it's more accurate to say that opening the box and seeing what happened cements one outcome into being. Schroedinger theorized that, until someone opened the box and saw if the cat activated the poison mechanism or not, then both outcomes were happening simultaneously, and the whole thing was in a sort of 'flux'. And while a rock would be affected by vibrations caused by the tree falling, that's not the same as saying that it would really make a 'sound'. It's only when it's interpreted in a certain way that it's actually a sound. In a small way, it's like the 'global superpositioning' theory...suppose you're the only one who hears a ball bouncing behind you. That ball, according to the theory, could actually be bouncing in a hundred different places at once, but when you turn and actually view it, then it's cemented in that one certain place. If you don't come away from quantum physics a little bit crazy, then you didn't really understand it. :P

look up some of these words if you need more info, this is off the top of my head, but i think the spelling is right...
The dark heartwood in the center of tree trunks is full of tannins and other recalcitrant, antifungal organics. Living cells in the wood (parenchyma cells in the xylem rays) grow into the dead, hollow, conducting cells (vessel elements and tracheids), where they produce these compounds and then die. This process is called tylosis. (tylosis is also the name for a disease, based on the same latin meaning)
