Evolution of the cochlea and the elongated cochlea allows for better sensitivity for higher frequencies. As in all lepidosaurs and archosaurs, the single-ossicle (columellar) middle ear transmits sound to the footplate of the columella, which sends a pressure wave through the inner ear. In snakes, the basilar papilla is roughly 1mm long and only responds to frequencies below about 1 kHz. In contrast, lizards tend to have two areas of hair cells, one responding below and the other above 1 kHz. The upper frequency limit in most lizards is roughly 5–8 kHz. The longest lizard papillae are about 2mm long and contain 2000 hair
Gold Is Where You Find It February 12, 1938 by Warner Bros. Pictures. A new gold strike in California ten years after the American Civil War triggers a bitter feud between farmers and miners using hydraulic mining methods that flood the farmlands.

During the early spring of 1937, producer Hal B. Wallis was looking for a project to film in Technicolor, as a dry run for "The Adventures
