series of inventions out of which this

company is continually experimenting.
I'VE net only make the white tubes
for the DAYLIGHT, but we are taking up
the problem of lighting rooms and
public buildings by a continuous light
tube, a yellow tube in this case, which
gives a peculiar yellowish, pinkisn |
brilliancy, very soft and pleasant as

many general purposes would serve !
better than the daylight window,
which is designed especially to be of
use in the industries.
I'VE are installing these daylight |
windows in dye works, textile mills,
oil refineries, lithographing plants, in
color works of every kind, throughout
he country. We have a number of
them in use in New York City-in the
New York Post-Ofice, in the New
York Central in Madison Square Gar
