Q. Why do we call a backward place a "jerkwater" town?
A. Steam engines needed to refill their boilers from water
towers next to the tracks but some "towns" were so small
that they lacked a water tower. When trains stopped in
those places, the crew had to find a nearby stream or well
and, bucket-brigade style, "jerk" the water to the train.
Those little dots on the map are jerkwater towns.
