DICTIONARY OF ORGAN STOPS.<br />
pervading tone which is so characteristic <strong>of</strong> the Diapasons <strong>of</strong> Father<br />
Smith, yet in far greater volume.<br />
Leathered<br />
Diapason<br />
(Diapason<br />
Phonon)<br />
showing<br />
leathered<br />
lip.<br />
Yet another attribute <strong>of</strong> Diapasons so treated, which renders<br />
them especially valuable in small buildings, is their facile<br />
speech, entirely free from that " spit " which is so <strong>of</strong>ten<br />
objectionably prominent in Diapasons <strong>of</strong> the old style at close<br />
quarters. In such buildings they also impart quite a "cathedral"<br />
roll to the tone. It would be possible to employ a very thick<br />
metal lip with a burnished instead <strong>of</strong> bevelled edge, but in<br />
actual practice it is found more satisfactory and convenient to<br />
cover a burnished lip <strong>of</strong> fair thickness with a strip <strong>of</strong> leather.<br />
The leather is passed round the lip, a short distance up the<br />
pipe on each side, being rendered adhesive by liquid fish glue<br />
or " Seccotine." Provided the metal be roughened with a file,<br />
the leather may be attached with ordinary glue, but as the<br />
latter is apt to crack with age, this method is best avoided.<br />
It is, perhaps, well to note that the s<strong>of</strong>tness <strong>of</strong> the leather<br />
affects the tone in no appreciable manner ; it is the thickness<br />
<strong>of</strong> the lip which is the important factor. Hohlflutes, and other<br />
open wooden Flutes, are sometimes made with thick lips<br />
covered with very thin leather or cartridge paper to impart<br />
smoothness and finish. Mr. Ernest Skinner, an eminent<br />
American <strong>organ</strong> builder, likens the discovery <strong>of</strong> the leathered<br />
lip to the invention by Barker <strong>of</strong> the Pneumatic Lever,<br />
predicting that it will revolutionize <strong>organ</strong> tone as surely and<br />
completely as did the latter <strong>organ</strong> mechanism. An estimate<br />
which is by no means so exaggerated as might be supposed.<br />
The leathered Diapason, indeed, is now attaining a zenith <strong>of</strong><br />
popularity both in England and America. A prominent<br />
German builder also, who on the author's recommendation<br />
made trial <strong>of</strong> it, was so struck with the refined quality <strong>of</strong> tone<br />
that he forthwith signified his intention <strong>of</strong> adopting the<br />
process. A few isolated and unsuccessful experimental<br />
attempts at improving the tone <strong>of</strong> the pipes by coating their<br />
lip with paper, parchment, felt, and kindred substances, have<br />
been recorded, but undoubtedly the credit <strong>of</strong> having been<br />
the first to perceive the value and inner significance <strong>of</strong> the<br />
process must be accorded to Mr. Robert Hope-Jones. It was<br />
only at the cost <strong>of</strong> considerable thought and labour that he<br />
was able to develop his crude and embryonic scientific theory into a<br />
process which bids fair to transform modern <strong>organ</strong> building. The names<br />
<strong>of</strong> Cavaille'-Coll and George Willis, and <strong>of</strong> Hope-Jones, will be handed<br />
down to posterity as the authors <strong>of</strong> the most valuable improvements in the
