This is the first entry in the “Catalog of Sensations,” a new category to which I’ll add photo, text, and sound entries that record a memorable sense experience.
A note about this entry: the sound of a pump-powered drinking fountain is filed in the subcategory “obsolete sound” for its rarity. The sound of a small machine that squeaks and clanks, and needs oil to function well, is rare in urban daily life (unless you ride a bicycle). It’s also rare for the entirety of a machine’s moving parts to be immediately visible: no plastic case to pry open, no hood to prop. In both its transparency and its susceptibility to weather, the pump reminds me of the bicycle.
