"NOTES ON ELECTRIC POWER SUPPLY FOR 

 TRAMWAYS AT PATERSON, NEW JERSEY." 



By Professor Fitzgerald. 



After a brief description of the situation of Paterson, the 

 President gave an account of the general arrangements of the 

 trolley car and overhead-wire system of electric tramways used 

 in the States as exhibited in the Pacerson installation. The total 

 length of tram lines worked by electricity is about thirty miles, 

 reckoned as single line. Nine engines with dynamos, capable 

 of developing about 150-horse power each, generate the current, 

 which keeps about forty cars running. The power is supplied 

 by an electric light company, who charge for it at the rate of 

 IIS per hundred car miles. Estimating the average power for 

 driving a car as 8-horse power, this is equivalent to a charge of 

 about i^d per Board of Trade unit. The reasons for the 

 diflference between this and the charge for electricity supplied 

 for light were pointed out. Professor Fitzgerald concluded by 

 acknowledging his obligations to Mr. Brock, the manager of the 

 Paterson Electric Light Supply Station, for information and 

 his kindness in showing and explaining the works.
