THE BRUSH ELECTRIC LIGHT. 



The attention of manufacturers and others who have occasion 

 to use artificial light to any considerable extent, is called to the 

 great economy in cost, and the great increase in light, afforded 

 by the BEUSH ELECTEIC LIGHT APPARATUS. There are 

 many situations in which it alone, of all the various artificial 

 lights, can do the work of illumination satisfactorily not only 

 because it costs less, but because it furnishes a volume of light 

 obtainable in no other way. Such situations are Rolling Mills, 

 Iron Foundries, Moulding Shops, and all Factories where there 

 are large, high ceiling rooms, as well as Docks, Warehouses, 

 Depots, Open Spaces, etc. In such places Electric Light has 

 been used to very great advantage — very largely used abroad, 

 and now to an increasing extent in this country. There are 

 other Factories, Mills, Shops, large Stores, Hotel Offices, The- 

 atres, Public Halls, etc., in which gas or oil has been used, and 

 they have furnished a sufficient amount of light; but, when all 

 the cost is counted up and the result compared, not only with 

 the cost but with the other great advantages of Electric Light, it 

 is found that the latter has the decided advantage, and it is 

 slowly but surely occupying the field. There are still other 

 places in which, when the cost of the necessary power to drive 

 the machine, taken in connection with the fact that a compara- 

 tively small amount of light is needed, in a number of rooms, or 

 for a very short time each day, are considered, it will be found 

 that Electric Light possesses no advantage in point of cost over 

 other lights, yet still retains its value as a pure white light, giv- 

 ing no heat and free from danger of explosion. 



So far as the Brush apparatus is concerned, it may be stated 

 with confidence that the experimental stage has been passed. It 

 has taken its place among the practical lights of the day, and is
