Where the Light can be Used 



Having been fullj^ perfected so as to produce Electric Light in 

 a perfectly practical manner, at a cost below that of any other 

 artificial light, and with the most complete safety, we are pre- 

 pared to make propositions for its introduction into localities 

 where considerable light is needed. The places where this light 

 can be used with the greatest economy, and where it is certain, 

 sooner or later, to supplant all other illuminating agents, are 

 FACTORIES, MILLS, SHOPS, DEPOTS, PARKS, DOCKS, 

 OPEN SPACES, CHURCHES, PUBLIC HALLS, THEATRES, 

 STORES, etc., and also in LIGHT-HOUSES; and as HEAD- 

 LIGHTS for STEAMERS, FERRY-BOATS and LOCOMO- 

 TIVES; also, for prejecting YIEWS, DIAGRAMS, etc., in 

 Lectures upon Scientific and other subjects. 



Electric Light is pure white, and therefore gives day colors to 

 all objects viewed by it. An equal amount of gas or oil light 

 produces nearly two hundred times as much heat and carbonic 

 acid gas, and costs from four to twenty times as much as the 

 Electric Light. There is no danger of fire or explosion in its 

 use. 



Parties desiring to use Electric Light for the above or similar 

 purposes, are invited to send us full particulars regarding the 

 buildings, rooms or places to be lighted, including dimensions, 

 character of walls and ceilings, amount of available power and 

 its location, amount of light now used, character of work being 

 done, length of time light will be needed continuously, etc. , etc- 



With these items before us, we will make a proposition to fur- 

 nish a COMPLETE OUTFIT FOR ELECTRIC LIGHT, put it 

 in perfect working order, and guarantee its success and perma- 

 nence. Opportunity will be given to test the apparatus thor- 

 oughly before concluding the purchase. 



The fullest investigation and the most exhaustive comparative 

 tests satisfy us that our apparatus is the BEST now before the 

 public, and that the BRUSH DYNAMO-ELECTRIC MACHINES 

 and BRUSH AUTOMATIC CARBON REGULATORS are, so 

 far, unequaled.
