The Fountain of Progress-North has a spiral layout of a series of jets featuring a changing and exciting trajectory cycle. Starting with a flat projection, the streams gradually rise in an advancing sequence, with the crown of the jet stream increasing from 2 to 16 feet in height. As the distance of the trajectory decreases, the action finally brings the central jet to a vertical position. The full effect remains set for a short period of time, then the process begins again but in reverse, until the streams return to their original flat projection. After a time lapse, the cycle is repeated. Two pumps, driven by 40-horsepower motors, deliver over 4,600 gallons of water per minute to produce this most unusual effect.
