When point A on the reed tuning wires is rigidly supported and held by force in its normal position, reeds can be made to stand in tune almost as well as flue pipes.
Figure 34 represents the Hope-Jones method of supporting the tuning wire at point A. It consists of having a brass tube T inserted in the block moulds before the block is cast. This tube T therefore becoming an integral part of the block itself. The inside bore of tube T is of such diameter that the tuning wire fits snugly therein.
In Figure 35 another method used by him for accomplishing the same purpose is shown. In this case a lug L is cast upon the block, forming, indeed, a portion of said block. The lower end of lug L is formed into a V, which partly embraces a tuning wire and supports it in such manner as to prevent improper movement of said tuning wire at point A.
When this method of construction is employed, the reeds are very much easier to tune, and, when once tuned, will stand infinitely better than reeds made in the ordinary way.

PROGRESS OF THE REVOLUTION IN OUR OWN COUNTRY.
In the study of the art of organ-building one cannot fail to be struck by the fact that almost all the great steps in advance have been due to Englishmen: the compound horizontal bellows, the concussion bellows, the swell box, the pneumatic lever, the tubular-pneumatic action, the electro-pneumatic action, the Universal air chest, the leathered lip, the clothed flue, the diaphone, smooth reed tone, imitative string tone, the vowel cavity, tone reflectors, cement swell boxes, the sound trap joint, suitable bass, the unit organ, movable console, radiating and concave pedal board, combination pedals, combination pistons and keys, the rotary blower--and many other items--were the inventions and work of Englishmen.
Speaking in general terms, this country lagged very far behind not only England, but also behind France, and even Germany, in the art of organ-building until comparatively a few years ago.
It has recently advanced with extraordinary rapidity, and if it be not yet in the position of leader, it is certainly now well abreast of other nations.
