A chinook salmon, having returned up the Mokelumne River to spawn, leaps against the closed gates of the fish hatchery at East Bay Municipal Utility Districts’s Camanche Dam.“Civilization creates for me a thousand other worlds that have little to do with my senses, a thousand illusions among which to choose. It is one of the functions of much of contemporary education and politics to convince me that my choices are limited to these creations.

I have come to love this discipline, now known as natural history, which delves ever more deeply into the physiological and behavioral differences between my species and others.
