In the 1830s at least 12.5% of all British mail was conveyed under the personal frank of peers, dignitaries and members of parliament, while censorship and political espionage were conducted by postal officials. Fundamentally, the postal system was mismanaged, wasteful, expensive and slow. It had become inadequate for the needs of an expanding commercial and industrial nation. There is a well-known story, probably apocryphal, about how Hill gained an interest in reforming the postal system; he apparently noticed a young woman too poor to claim a letter sent to her by her fiancé. At that time, letters were normally paid for by the recipient, not the sender. The recipient could simply refuse delivery. Frauds were commonplace: for example, coded information could appear on the cover of the letter; the recipient would examine the cover to gain the information, and then refuse delivery to avoid payment. Each individual letter had to be logged. In addition, postal rates were complex, depending on the distance and the number of sheets in the letter.
