THE CONQUEST OF TIME AND SPACE 



drums actuated by electricity which raise and lower the 

 cars by means of cables. On the cars themselves, there- 

 fore, there is no power, but each car is equipped with 

 brakes powerful enough to stop and hold it notwith- 

 standing the steepness of the incline. 



There is nothing particularly novel in the principles 

 involved in this aerial road, but it is the first of its kind 

 to be built for passenger traffic. Similar less preten- 

 tious roads have been in use for freight transportation 

 for several years. But the success of this road means 

 the building of others on inaccessible mountain inclines 

 where the laying of ordinary roadbeds is out of the 

 question, and the operating of cog roads too expensive.
