 Brush Electric Light Co.: 



Gentlemen — I have just returned from the Deer Creek Mine, 

 near Smartsville, which is now lighted at night by three lanterns 

 of 3,000 candle power each, supplied from a Brush Electric Ma- 

 chine furnished by you. The light thus produced enables the 

 company to work the mine at night practically as well as by day. 

 The machine requires but little attention and the expense is 

 small. Should the apparatus continue to work as well as at 

 present, the company will be entirely satisfied. 

 Tours truly, 



GEO. P. THURSTON, Secretary.
