Alone or sometimes in pairs, the beaver sets to work with its powerful incisors, gnawing, cutting, and chipping away the wood near the base of the tree in a V-shaped pattern, often laboring for hours at a time, until the tree is left balancing precariously on a narrow point or wedge of wood, often no thicker than a pencil. With one more cut or a providential gust of wind, the connecting wood fibers rupture as the tree begins to fall. Sensing the vibrations through its teeth or hearing the wood crack, the beaver scampers out of harm’s way. Some people claim that beavers can predict which way a tree will fall, or that they cut the trees so that it falls in the direction of their choosing. This is not true, and a small number of beavers are so clueless on this account that, failing to get out of the way of the crashing lumber, they end up serving as their own executioners, crushed to death by the tree they have just felled.
