In this article, taken from The Ludgate Magazine (London, 1899), we have a veritable feast for collectors of TPOs. It is certainly unusual to see the operations of travelling post offices in the nineteenth century.
The postal system of the country may be taken as part and parcel of the railway, for the G.P.O. would indeed be a shortlived institution should it ever strive for indepenence.
In the year ending March 1894, we were informed that the number of letters, postcards, book-packets, circulars, samples, newspapers and parcels sent through the Post Office was 2,796,500,000 and that the bulk of this was transmitted by rail.
