| ETC.. in the exact center of the organ are the
pipes which are so arranged that no por-
tions Of woodwork or interior of the organ
are visible. The two central towers mask
ing in the keyboards are composed Of seven
16-foot pipes drawn from the double open
diapason on the great The tints
Of these large metal pipes are deep chocolate
relieved by broad skyblue bands wOr ked ont
with silver-gilt arabesques. The pipes be-
tween the two main towers are from the
same stop and graduated in length to q
graceful curve. Their upper halt is in cafe
au lait with gilt patterns. and the lower
portion is in pale blue with silver-gilt pat
terms. In the next two panels the colors are
Just reversed, and the next two towers, one
on either side, are smaller, but in the same
design and colors. The next two panels are
formed of the big, square wooden pipes OF
the pedal open diapason, painted chocolate
brown, and their mouths heavily gilt with
gold and silver bands. The two corner tow
ers are formed of pipes taken from the pedal
Violoncello and alike in color to the other
towers. The sides are formed of smaller
wooden pipes handsomely decorated;
AN ARTISTIC EFFECT.
1t is dificu to analyze so exquisite an
effect as the case taken as whole produces.
There is nothing glaring or obStreperous in
of the pipes. The eye is rested by the quiet
tone of the whole design, and although it
must be seen to be appreciated it cannot fail
to'please the most exacting eve. By follow
ing SO broad a plan the entire end of the
hall is apparently and also literally occu-
pied.
The interior of the organ appeals to the
mechanician. It is as highly finished as the
average piano, remarkable thing so far as
organs go. 1t is evident that Roosevelt &
Co. have felt that the organ was to be a
criterion of their manufacture.
In general terms the wind chests of the
great and choir organs are upon the same
level, feet above the floor. Beneath these
are the two regulating bellows. The swell
organ is inclosed in massive swell-box 20
feet above the floor, and is directly above
the center of the two other wind chests. All
of the organs are hedged in by swell shades,
giving unlimited opportunity to the player
to produce crescendo and decrescendo
effects. The astonishing roominess of the
interior of the organ is worthy of note. In
most organs tuners are forced to become ex.
pert acrobats in order to reach refractory
pipes or actions; but in the Carnegie organ
every portion OF it is easily accessible. The
entire stop action can be adjusted in COM
binations at will, and in it are embodied
acter.
THE LUNGS OF THE ORGAN.
Underneath the organ floor are two huge
bellows operated by adjustable Ross water
motors. The air is conveyed upward to
supplemental reservoirs beneath the wind
chests. The weights upon the latter
are so adjusted that the Pedal organ
is upon what is technically known as
5-inch wind. the Great upon
4inch, and the Swell upon 3<-inch.
The explanation of this method lies in
filing chemists glass tube with water,
and the amount of displacement in inches
is the basis of the above measurement This
unequal wind power is very desirable in
noVation, as much freer voicing OF the pipes
is thereby permitted, resulting in a corre-
spending betterment of tone. Nearly all
organs of the present day are upon a three
inch wind.
Reverting to the mechanism, every pipe
in the organ has its own valve, and is there
fore independent. Should trifing disar-
rangement take place, the closing of one
stop will allow Of use of the particular
organ in which the accident happened,
thing not possible under the usual methods
of organ making. The entire interior action
is pneumatic and noiseless, as we'll as re-
markably prompt in response to demand.
Many useful appliances are included in the
general interior details.
THE INVITING KEYP1 ARDS.
The three claviers are of the most exquis-
ite finish, and are resplendent in ivory and
ebony. The recessed ends are special
feature, allowing the closer placing of the
keyboards and the easier transference
OF the hands Of the organist from one key |
board to another.
It is also possible to obtain view of the |
pedal combinations without craning ones |
neck to the danger point. The action of the |
keys is wonderfully easy owing to the |
pneumatic attachments. The stop-knobs |
and mechanical accessories are in high |
state of finish and the pedal claVier is a
handsome piece of work. The keyboards |
invite the touch of the musical enthusiast. |
Timing has just been commenced by Mr.. |
Davis and his assistants and will be finished |
next week. It Is early to speak of the tone
of the instrument as it is not in shape to ex-
pertinent with, but from the liquid melodi-
business of isolated stops it is safe to assume
that the ensemble of the organ will be found |
quite up to the hopes of Messrs. Carnegie, |
Scott and Mellor, and the assurances of the
organ builders.
