e name of "Chimes"
these resonant gongs are now finding place in many Church and Concert
organs. Tubular bells are also used in a similar capacity by all the
leading organ-builders,

The greatest development in this direction is found in the Hope-Jones
Unit Orchestra. In these instruments fully one-third of the speaking
stops rely on percussion for production of their tones. Even small
instruments of this type have all got the following percussion stops:
Chimes, Chrysoglott, Glockenspiel, Electric Bells (with resonators),
Xylophone, and carefully-tuned Sleigh Bells--in addition to single
percussive instruments, such as Snare-drum, Bass-drum, Kettle-drum,
Tambourine, Castanets, Triangle, Cymbals, and Chinese Gong.

As all these tone producers are enclosed in a thick Swell box, an
artist is able to employ them with as much refinement of effect as is
heard when they are heard in a Symphony Orchestra.

Mr. Hope-Jones informs the writer that he has just invented an electric
action which strikes a blow accurately proportioned to the force
employed in depressing the key, thus obtaining expression from the
fingers as in the pianoforte. He will apply this to the percussion
stops in organs he may build in the future.

When skilfully employed many of these percussion stops blend so
perfectly with the flue and reed pipes that they become an important
integral part of the instrument--not merely a collection of fancy stops
for occasional use.

THE DIAPHONE.

The invention of the Diaphone by Hope-Jones in 1894 will some day be
regarded as the most important step in advance hitherto achieved in the
art of organ building. The existence of patents at present prevents
general adoption of the invention and limits it to the instruments made
by one particular builder. In addition to this the Diaphone takes so
many forms and covers so large a field that time must necessarily pass
before its full possibilities are realized.

Enough was, however, done by Hope-Jones in connection with the organs
he built in England a dozen or eighteen years ago to leave the
experimental stage and prove the invention to be of the greatest
practical importance to the future of organ building. The author's
opinion that before long every new large organ will be built upon the
Diaphone as a foundation, is shared by all who have had opportunity to
judge. By no other means known to-day can anything approaching such
grand and dignified Diapason tone b
