  3. 3. EAB/FJT/GA Gino Masini | 2016-04-28 | Page 3 “… You could make telephone calls from the car… there were two long sticks, like fishing rods, handled by Hilda. She would hook them over a pair of telephone wires, seeking a pair that were free... When they were found, Lars Magnus would crank the dynamo handle of the telephone, which produced a signal to an operator in the nearest exchange.” The Ericsson Chronicle connected cars, circa 1910
