This is what “a beautiful, fresh, sunny morning” was like for Werner Herzog during the Sisyphean miseries that plagued the shooting of his Amazonian epic “Fitzcarraldo” (1982): one of two newly hatched chicks drowned in a saucer containing only a few millimeters of water. The other lost a leg and a piece of its stomach to a murderous rabbit. And Mr. Herzog realized, for the umpteenth time, that “a sense of desolation was tearing me up inside, like termites in a fallen tree trunk.”

These and other good times have been immortalized in “Conquest of the Useless,” Mr. Herzog’s journal about his best-known filmmaking nightmare. Already published in German as the evocatively titled “Eroberung des Nutzlosen” in 2004, this book, translated by Krishna Winston, seemingly recapitulates some of Les Blank’s film “Burden of Dreams,” the 1982 documentary that captured the “Fitzcarraldo” shoot in all of its magnificent, doomy glory. When he spoke to Mr. Blank, Mr. Herzog used the phrase “challenge of the impossible” to describe his heroic, arguably unhinged struggle to complete his film.

But “Burden of Dreams” never penetrated Mr. Herzog’s rogue thoughts, at least not in the way his own mesmerizingly bizarre account does. That’s understandable: Mr. Blank could concentrate on such external diversions as hauling a steamship over a hill in the Amazon rain forest, which was the pièce de résistance of Mr. Herzog’s “Fitzcarraldo” scenario.

The observations to be found in “Conquest of the Useless” are much more private and pitiless, as Mr. Herzog finds evidence of an indifferent universe wherever he turns. With the same bleak eloquence that he brings to narrating his nonfiction films (and what voice can match Mr. Herzog’s for mournfully contemplative beauty?) this book describes the exotica of the jungle. Obsessed with the bird, animal and insect worlds as a way of avoiding the human one, Mr. Herzog keeps a steady record of the perverse spectacles he encounters.
