Mark of the Beaver part Deux

While on a kayak trip recently I saw the following evidence of strategic chewing…

Hard to believe beavers have this level of intention in designing and building structures from wood. I recall an economics professor of mine at New York University who was a graduate of MIT. His school ring had an image of a beaver, the animal considered to be the “Engineer of the natural word”.l word” .

He also relayed a funny anecdote, which is that students wear the ring with the beaver facing them and then turn it around after graduation — the explanation?  That during the hard work of earning a degree there, the beaver “shits on you”, and once you have graduated, the beaver “shits on the world”, or something like that.
