Beavers

A genuine, inhabited beaver lodge, somewhere near Ottawa.

Some bright spark claimed that I had turned my head at the one time that a beaver poked his head above the water. Hand up for chickadees.

It seems that a lot of beavers went to make top hats, some of them for people from first nations. It is not at all clear to me how you get from brown beaver fur to black top hat, but I do recall reading that beaver fur is the most waterproof fur known to man and is very good for making hats.
