Though it pains me to have to agree with Sagan about anything, he's right: the "canals" _were_ optical illusions of the sort generated by the mind's effort to make sense of ambiguous stimuli. Late 19th-C. astronomers who participated in the controversy were far from unanimous in detecting canals on the Martian surface. There's no reason, in other words, to think the "canals" once existed but later vanished. In the interest of full and shameless plug, my most recent book, Hidden Realms, Lost Continents, and Beings from Other Worlds, details the canal controversy in the chapter "The Not-So-Dying Race: Martians Envisioned and Encountered." Another discussion can be found in Thomas E. Bullard's recent The Myth and Mystery of UFOs (University Press of Kansas). Jerry Clark Listen to 'Strange Days...
