From this period the clerks, who had been the only ones entrusted with the high responsibility of sorting and despatching letters, gradually became a restricted and exclusive class, while the lesser officials, who formerly had been scarcely allowed to touch the correspondence, were now trained to those superior duties, but without a corresponding increase of remuneration. It is worthy, however, of bearing in mind that the despatching of mails was still deemed of such a responsibility and importance that mere letter-sorters were not yet allowed to perform such duties, clerks only on a salary rising to £400 a year being thought worthy of that honour, although a few years later, when such duties became several times heavier and correspondingly more responsible, the inferior class of letter-sorters were compelled to take them up. It was the continuance of this anomaly for some length of time, indeed, which constituted one of the main elements of discontent, and came to be regarded as a distinct grievance among the letter-sorting staff especially. As the growth of the Post-Office business necessitated a larger staff to cope with it, so a new class of men were being slowly introduced. The penny post was a reform so much appreciated by the public by this time that it had become even now, in 1854, the most flourishing business in the world. And Rowland Hill was not slow to take every advantage of his discovery that the Post-Office contained greater possibilities than to remain a cheap public convenience. The founder of the penny post was now Permanent Secretary, and a greater power in the land than the Postmaster-General, not a little of a bureaucrat, and one who had trained himself to regard his postal domain as a sort of family preserve. He saw no harm in introducing cheap labour; he discovered a new way of cutting down expenses by relegating the work which had been paid for at a salary of from £200 to £400 a year to this new class of minor officials, mostly salaried at less than a fourth that amount. There was one new element introduced with the new-comers, however, which probably was never taken into account at the time; and that was, that they were drawn from a better educated, and a more enlightened body of men than those hitherto engaged on inferior duties. The educational tests for admission into the Post-Office had previously been very meagre, and almost nil where special influence had been used. The old system of patronage and nomination was maintained as long as it was convenient, and as long as it worked satisfactorily, and for some considerable time longer. But at length, owing to the expansion of postal business, even patronage could not of itself keep up an adequate supply of qualified recruits. And it was impossible to go begging to lords or distinguished commoners for poor relations, or cast-off dependants, as that might be putting a premium on dishonesty, and cheapening still further good recommendations which
