Still by the pond... I saw this muskrat busily gathering cattails. He would reach down into the water and grab a stalk, stick his head down and chew off the entire plant, then let it float on the water while he worked on another. When he had as many as he could handle, he gathered them all in his mouth and swam off toward a dense and large stand of dead cattails ringed with fresh ones. At one point he dove underwater and vanished. I could also see where he had been cutting the Flowering rush and leaving he stems to float on the water's surface.
