If used in the cities, it would not disfigure the streets as does an ordinary elevated road; in fact, its appearance would not differ greatly from the ordinary trolley poles and wires and would not shut out sunlight nor drop oil or clinkers on the street, as do elevated steam roads.

The danger from collisions would be minimized, and yet it would be possible to attain greater speed than on an ordinary surface road. As the inventor's theory is, that the great momentum would lessen the weight of the car as it flew through space, a system of tilting planes under the car is arranged for. These planes would be adjusted by the

San Fernando is the center of the great olive industry of California, though there are many large olive orchards in other sections of the state. There are the oldest olive trees in California, having been planted by the Spanish padres more than a century ago.

The olive industry has been, and is constantly increasing in California since its first introduction by the early Spanish mission fathers; and the olive culture can never be overdone in that state since the olive fornia, New Mexico and Arizona, with groves of the Mount or Olives in the profitable success.
