The penny post was found to be a great and decided success. No sooner, however, was that success apparent, and it was known that the speculation was becoming lucrative to its originator, than the Duke of York, by virtue of the settlement made to him, complained of it as an infraction of his monopoly. Nor were there wanting other reasons, inducing the Government to believe that the penny post ought not to be under separate management. The Protestants loudly denounced the whole concern as a contrivance of the Popish party. The great Dr. Oates hinted that the Jesuits were at the bottom of the scheme, and that if the bags were examined, they would be found full of treason.[19] The city porters, too, complained that their interests were attacked, and for long they tore down the placards which announced the innovation to the public. Undoubtedly, however, the authorities were most moved by the _success_ of the undertaking, and thereupon appealed to the Court of King's Bench, which decided that the new post-office, with all its profits and advantages, should become part and parcel of the royal establishment. Docwray was even cast in slight damages and costs. Thus commenced the _London District Post_, which existed as a separate establishment to the _General Post_ from this time until so late as 1854. It was at first thought that the amalgamation of the two offices would be followed by a fusion of the two systems; but this fusion, so much desired, and one we would have thought so indispensable, was not accomplished (from a number of considerations to be adduced hereafter), although the object was attempted more than once. About a year after the new establishment had been wrested from him, Mr. Docwray was appointed, under the Duke of York, to the office of Controller of the District-Post. This was doubtless meant as some sort of compensation for the losses he had sustained.[20]
