.Automobile Sleigh Develops Speed of 35 Miles an Hour on Snow Roads
LESTER COBB, of Norway, Maine, has invented an automobile sleigh which will not mire in ruts or drifts of snow. It drives and operates like an automobile. A paddle arrangement gives it traction. The auto-sleigh is geared for rapid traction and 35 m.p.h, is a comfortable speed with it. It is declared that the deeper the snow the faster the speed of the sleigh.
