M. H. McCARTHY.
American Luxfer Prism Co.,
|Chicago, September 2, 1897.|
I enclose you gas bills of 1896, and the
corresponding ones for 1897, covering the period which the Prisms
have been in my store. They speak more with force than I can. I
am confident that I shall not find it necessary to use gas or
artificial light during the day at any time the coming season.
Heretofore, I have had two to four gas jets burning all day in
the back of my store, and now we will use none.
