"Barker's connection with Cavaillé was not of long duration, and we next find him in the Daublaine & Callinet organ-building company. At this time the company was rebuilding the magnificent organ at St. Sulpice, the acknowledged masterpiece of Cliquot, the French 'Father Schmidt.' * * *
"During the time this restoration of the organ was in hand, Louis Callinet experienced acute financial difficulties, and, failing to induce Daublaine, his partner, to advance him a relatively small sum, * * * Callinet became so bitterly incensed that one day, going to the organ on some trifling pretext, he entirely wrecked it with axe and handsaw.
"This act of vengeance or criminal folly involved Daublaine in the same financial ruin as himself, and through this tragic occurrence the firm in which Barker was beginning to be securely established came to an end. Callinet, being absolutely penniless, was not prosecuted, but ended his days in the employ of Cavaillé as voicer and tuner.
"Nor was this the only disaster which occurred during the time Barker was with Daublaine & Callinet. In 1844 (December 16th), it was Barker's ill-fortune to kick over a lighted candle while trying to remove a cipher in the organ his firm had recently erected in St. Eustache, which occasioned the total destruction of the organ. * *
"The outlook seemed unpromising for Barker when the firm of Daublaine & Callinet came to an end. The good will of that concern was, however, purchased by M. Ducroquet (a capitalist), who entrusted him with its management.
"J. B. Stoltz, Daublaine & Callinet's foreman, a very able man and a splendid workman, feeling aggrieved at Barker's promotion, seceded and set up for himself, his place in the new firm being filled by M. Verschneider, in whom Barker found efficient support in matters of technical knowledge and skill.
"During the time Barker was with M. Ducroquet the present organ at St. Eustache was built, to replace that so unfortunately destroyed by fire; also an organ which was exhibited at the great exhibition of London in 1851. * *
*"In the Paris exhibition of 1855 Barker was admitted as an exhibitor, independently of M. Ducroquet (who was in bad health and on the eve of retiring from business), obtaining a first-class medal and nomination as Chevalier of the Legion of Honor.
