I was walking along the river and heard the strangest noise. It was one of those noises which, when I found out what It was, sounded exactly as it should. A beaver was chewing at a branch on the bank of the river. First there were small rolling noises as the branch went through its hands, and then the 'gnaw gnaw gnaw', and then the turning noise and the cycles were repeated.
This went on fifteen minutes or so, then the beaver and I both heard noises in the water. We both saw another beaver approaching. The beaver-at-gnaw quickly went in her direction (though I can only guess which sex was which). They swam toward each other, then rubbed faces. The approaching beaver made small bawling noises like a young calf. They rubbed bodies and seemed to sniff each other, then they swam in different directions. This performance - the swimming away, the languid circling, the approaches - went on for twenty minutes. A couple of times the 'gnawing' beaver clambered over the over beaver's back, but this lasted just a few seconds. The beaver which approached rubbed noses once again, and made the bawling sounds one more time.
I never appreciated how large beavers are until one of them came up on the bank. The water was clear enough to see their feet and tail move underwater (I wonder if the portion out of the water might have the 1/10 proportion of an iceberg). The sun was setting and they became difficult to see. However they decided to part anyway. One began to go down river toward the harbour and one headed to the other shore. For me an experience of a lifetime.
