There has not hitherto been published any detailed account of the first establishment, in this country, of the Post Office as a public institution; nor does it appear that anything has been made known of the men who were instrumental in building up this useful fabric, in the years of its infancy, beyond the barren mention of their names. In some cases, moreover, in such bald notices as have been given of the early posts, important names are wholly omitted, and in others the names of men are associated with events in which they had little concern. What is disclosed in the following pages is an attempt not only to give a fairly full and true account of the first forty years' existence of the Inland Posts in Britain, but to tell something of the men to whom the credit is due of contriving and bringing into working shape this great machine of public convenience and utility. The facts here narrated are collected from the Public Records, original documents, and other authentic sources. In the extracts which have been made from original papers, modern orthography, as being more convenient for the reader, has been generally employed; but in a few cases the tone and flavour of the antique have been retained in the original spelling.
