It’s not hard to see where beaver teeth have been at work along the edge of a stream, lake or pond. Stumps of felled trees at times look as if they’ve been worked on with a giant pencil sharpener. The beaver is certainly one of the more interesting rodents in the world, besides being the second largest. It’s famous for its fine fur, well known for its broad tail, and at times considered a nuisance because of damage caused by its teeth.
