The large resonator on the floor was built by
the late Forest Cheney, inventor of the Cheney
phonograph, for concert purposes. It is now
used for acoustic analysis in connection with
the manometric apparatus. It is also the finest
radio loud speaker horn I have ever heard.
The small work bench is power equipped, hav-
ing a combination drill press, portable power
drill, brace, and power sawing table. This outfit
is used for making small wooden patterns or
other light woodwork which may come up as
incidental to scale drafting or tonal investiga-
tions.
Above the work bench is a cross-sectional
model made by Steinway & Sons of their style
B grand piano. The model is faithfully built to
scale and every detail is exactly reproduced.
Even the bars of the iron plate are set in exactly
(but made of wood), with every dimension
faithfully followed. The great value of this
model lies in its at once revealing to the eye
the relations of all parts in grand piano con-
struction, something for which one daily thanks
the makers. Steinway & Sons very generously
placed this model at my disposal some time ago,

construction which is being pushed forward as
rapidly as possible, the need for an inside view
of construction became imperative as a check
against errors.
