While Ralph and the linemen crews were building transmission lines, Nathan Jones opened the Electrical Development and Supply Company store in Larned. It sold all manner of electrical appliances, from irons to ranges to fans.
During the fall and winter of 1918, Nathan Jones tirelessly promoted this vision of providing electricity to small towns in the Pawnee and Arkansas valleys and connecting farms for irrigation by electric pump. He held dinners for local farmers where he promoted his plan.
After returning from military duty in the summer of 1919, Ralph Jarvis went to work as a lineman for the Pawnee Power and Water Company. The company was building transmission lines to several small towns around Larned.
