From American Art Journal (Oct. 5, 1878): "The grand organ now standing in the Fair of the American Institute, erected by Messrs. George Jardine & Son, of this city, is a source of great attraction. It is performed upon daily by several of our first-class organists, and the compositions of the great masters are, from the capabilities and mechanical improvements in this instrument, rendered with most charming effects; in fact, it comprises all the advantages of the best concerted bands of wind and even string instruments, as all modern improvements are herein carried out."
"Among the various improvements of which Mr. Jardine was absolutely the very first to introduce and invent, are the combination and reversible pedals, his own invented pneumatic and vacuum pallets or valves, now generally used by the English organ builders, and accredited to him in "Hompkins & Rimbault's work on the Organ;" also, vertical swell blinds or "shades," which render a single set more effective, both as in crescendo and sforzando, than the double blinds as usually contrived. Mr. Jardine was also the very first to introduce, many years ago, the projecting or overhanging keys, now universally copied, without the least acknowledgment of that fact; also, the grand improvement of reversed bellows ribs, which entirely remedied the unsteady variableness of the wind caused by careless blowing. He was also the very first to introduce the vox angelica, the clariana, flute harmonique, Viol di Gamba, the French vox humana and French tremolo."
