one speed to another without jolt, jerk, or jar. The driver is not compelled to keep his eye on a water-gauge or the contents of a fuel tank, or to manipulate change-speed gears, sparking levers or the like. All he need trouble about is his steering gear and the position of his controller, with a very occasional glance at his voltmeter and ammeter. Above all the electromobile has no odour of its own, nor does it incur any danger of being run in by intelligent police constables for showing vapour and at the same time travelling above four miles an hour.
