American Luxfer Prism Co.,
|Chicago, August 17, 1897.|
The Rookery, City.
In regard to the Prisms which you installed in
our flat in the Manhattan building, at Deming and Hampden courts, I
would say that the results are remarkable. We have a dining room which
was quite dark, and where we were obliged to use gas more or less of the
time, but since your Prisms have been installed we have not had to use
our gas either at breakfast or dinner, or during the day, and when the
sunlight strikes the Prisms in the afternoon, our dining room is filled
with sunshine in every part, where there has never been a ray before.
There are times during the day when this dining room is the brightest,
sunniest room we have in our flat, although we have other rooms in which
the windows open on much larger courts, and on the open street.
Yours very truly,
