Show Will Pullman Follow Suit? All the trains on the District railway will soon be provided with electric reading read-ing lamps, to be worked upon the "pen-py-in-the-slot" principle. Preparations are so far advanced that the wiring of the carriages is nearly completed. About 2,500 lamps will be required. They are very ingeniously constructed. A penny dropped into the box will set a small clock in motion for half an hour, during which, time the current will be switched on, and the lamp will throw its concentrated concen-trated rays direct upon the book or newspaper news-paper of the passenger who pays for it and nobody else. Should any mischievous mischiev-ous person tamper with the apparat us an electric warning will be sounded in the guard's van. Each lamp will be of 20 candle power, and there will be four in each compartment. The current is derived de-rived from a battery, which will supply four lamps. No date can be assigned for the commencement of this special system sys-tem of illumination, but it is probable that it will be inaugurated some ti this month. London Telegraph. |
