The city of Cleveland, Ohio, has some very steep streets. Over a year ago a mechanical device was installed to overcome the difficulty. A traveling roadway or rolling road is the name given to this labor-saving invention.

The two photographis show such a roadway as is in use in Cleveland, on Factory street hill. The mode of operation is as follows: A wagon heavily laden with in
