Rh produced.) "It was to some of the bass pipes of the organ he built for the Church of Attercliffe, near Sheffield, in the year 1827, that Booth first applied his little invention. The lower notes of the wood open diapason of the GG manual were placed on a small separate sound-board, and to the pull-down of each pallet he attached a small circular bellows underneath. From the great organ soundboard groove a conveyance conducts wind into this bellows, which, opening downward, draws the pallet with it. These small bellows Mr. Booth used to call 'puff:-valves.'"

Since Booth's experiments in this direction many European builders,among them Cavailld-Coll, of Paris, have contributed to the application of pneumatics, with the most remarkable results. American builders have not been behindhand either in adapting and improving upon the inventions of their contemporaries abroad, and their work is to be found illustrated the magnificent instruments erected in various cities throughout the States. Jardine & Sons are admitted a leadership by the fourscore and odd organbuilders who constitute the business in the United States and the British Dominion. The founder of this eminent house, George Jardine, was born in Dartforth, England, November 1, 1801.
