The single gallon of oil in the tank wnllrun the machine under favorable conditions for a hundredmiles. The machine is suited to all weathers. When itis extremely hot the rider can cool himself in the breezecreated by the motion. When it is quite cold, he canswitch the exhaust air, which is hot, into the handle-barsand frame and warm himself. In dusty and muddyweather the large tires enable the machine to progressmore easily than any other form of vehicle. An attach-ment for the front wheel, in the shape of a pair of adjust-able runners, is designed for use in winter, when a sleigh-ride is desired. If bare ground is struck after a time therunners are switched up, and tlie journey continued onwheels. The frame is so low tliat the rider can place hisfeet on the ground in stopping or starting.
